CHANGELOG.md

@@ -5,6 +5,556 @@ All notable changes to **Pipecat** will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [Unreleased]
+
+### Added
+
+- Introduced pipeline frame observers. Observers can view all the frames that go
+  through the pipeline without the need to inject processors in the
+  pipeline. This can be useful, for example, to implement frame loggers or
+  debuggers among other things.
+
+- Added `30-observer.py` to show how to add an Observer to a pipeline for
+  debugging.
+
+- Added `OpenRouter` for OpenRouter integration with an OpenAI-compatible
+  interface. Added foundational example `14m-function-calling-openrouter.py`.
+
+- Added a new `WebsocketService` based class for TTS services, containing
+  base functions and retry logic.
+
+- Added `DeepSeekLLMService` for DeepSeek integration with an OpenAI-compatible
+  interface. Added foundational example `14l-function-calling-deepseek.py`.
+
+- Added `FunctionCallResultProperties` dataclass to provide a structured way to
+  control function call behavior, including:
+
+  - `run_llm`: Controls whether to trigger LLM completion
+  - `on_context_updated`: Optional callback triggered after context update
+
+- Added a new foundational example `07e-interruptible-playht-http.py` for easy
+  testing of `PlayHTHttpTTSService`.
+
+- Added support for Google TTS Journey voices in `GoogleTTSService`.
+
+- Added `29-livekit-audio-chat.py`, as a new foundational examples for
+  `LiveKitTransportLayer`.
+
+- Added `enable_prejoin_ui`, `max_participants` and `start_video_off` params
+  to `DailyRoomProperties`.
+
+- Added `session_timeout` to `FastAPIWebsocketTransport` and
+  `WebsocketServerTransport` for configuring session timeouts (in
+  seconds). Triggers `on_session_timeout` for custom timeout handling.
+  See [examples/websocket-server/bot.py](https://github.com/pipecat-ai/pipecat/blob/main/examples/websocket-server/bot.py).
+
+- Added the new modalities option and helper function to set Gemini output
+  modalities.
+
+- Added `examples/foundational/26d-gemini-multimodal-live-text.py` which is
+  using Gemini as TEXT modality and using another TTS provider for TTS process.
+
+### Changed
+
+- Updated the `17-detect-user-idle.py` to show how to use the `retry_count`.
+
+- Enhanced `UserIdleProcessor` with retry counting functionality. Callbacks now
+  support an optional `retry_count` parameter to implement escalating responses
+  to user inactivity.
+
+- Modified `UserIdleProcessor` to start monitoring only after first
+  conversation activity (`UserStartedSpeakingFrame` or
+  `BotStartedSpeakingFrame`) instead of immediately.
+
+- Modified `OpenAIAssistantContextAggregator` to support controlled completions
+  and to emit context update callbacks via `FunctionCallResultProperties`.
+
+- Added `aws_session_token` to the `PollyTTSService`.
+
+- Changed the default model for `PlayHTHttpTTSService` to `Play3.0-mini-http`.
+
+- `api_key`, `aws_access_key_id` and `region` are no longer required parameters
+  for the PollyTTSService (AWSTTSService)
+
+- Added `session_timeout` example in `examples/websocket-server/bot.py` to
+  handle session timeout event.
+
+- Changed `InputParams` in
+  `src/pipecat/services/gemini_multimodal_live/gemini.py` to support different
+  modalities.
+
+- Changed `DeepgramSTTService` to send `finalize` event whenever VAD detects
+  `UserStoppedSpeakingFrame`. This helps in faster transcriptions and clearing
+  the `Deepgram` audio buffer.
+
+### Fixed
+
+- Fixed `UserIdleProcessor` not properly propagating `EndFrame`s through the
+  pipeline.
+
+- Fixed an issue where websocket based TTS services could incorrectly terminate
+  their connection due to a retry counter not resetting.
+
+- Fixed a `PipelineTask` issue that would cause a dangling task after stopping
+  the pipeline with an `EndFrame`.
+
+- Fixed an import issue for `PlayHTHttpTTSService`.
+
+- Fixed an issue where languages couldn't be used with the `PlayHTHttpTTSService`.
+
+- Fixed an issue where `OpenAIRealtimeBetaLLMService` audio chunks were hitting
+  an error when truncating audio content.
+
+- Fixed an issue where setting the voice and model for `RimeHttpTTSService`
+  wasn't working.
+
+- Fixed an issue where `IdleFrameProcessor` and `UserIdleProcessor` were getting
+  initialized before the start of the pipeline.
+
+## [0.0.52] - 2024-12-24
+
+### Added
+
+- Constructor arguments for GoogleLLMService to directly set tools and tool_config.
+
+- Smart turn detection example (`22d-natural-conversation-gemini-audio.py`) that
+  leverages Gemini 2.0 capabilities ().
+  (see https://x.com/kwindla/status/1870974144831275410)
+
+- Added `DailyTransport.send_dtmf()` to send dial-out DTMF tones.
+
+- Added `DailyTransport.sip_call_transfer()` to forward SIP and PSTN calls to
+  another address or number. For example, transfer a SIP call to a different
+  SIP address or transfer a PSTN phone number to a different PSTN phone number.
+
+- Added `DailyTransport.sip_refer()` to transfer incoming SIP/PSTN calls from
+  outside Daily to another SIP/PSTN address.
+
+- Added an `auto_mode` input parameter to `ElevenLabsTTSService`. `auto_mode`
+  is set to `True` by default. Enabling this setting disables the chunk
+  schedule and all buffers, which reduces latency.
+
+- Added `KoalaFilter` which implement on device noise reduction using Koala
+  Noise Suppression.
+  (see https://picovoice.ai/platform/koala/)
+
+- Added `CerebrasLLMService` for Cerebras integration with an OpenAI-compatible
+  interface. Added foundational example `14k-function-calling-cerebras.py`.
+
+- Pipecat now supports Python 3.13. We had a dependency on the `audioop` package
+  which was deprecated and now removed on Python 3.13. We are now using
+  `audioop-lts` (https://github.com/AbstractUmbra/audioop) to provide the same
+  functionality.
+
+- Added timestamped conversation transcript support:
+
+  - New `TranscriptProcessor` factory provides access to user and assistant
+    transcript processors.
+  - `UserTranscriptProcessor` processes user speech with timestamps from
+    transcription.
+  - `AssistantTranscriptProcessor` processes assistant responses with LLM
+    context timestamps.
+  - Messages emitted with ISO 8601 timestamps indicating when they were spoken.
+  - Supports all LLM formats (OpenAI, Anthropic, Google) via standard message
+    format.
+  - New examples: `28a-transcription-processor-openai.py`,
+    `28b-transcription-processor-anthropic.py`, and
+    `28c-transcription-processor-gemini.py`.
+
+- Add support for more languages to ElevenLabs (Arabic, Croatian, Filipino,
+  Tamil) and PlayHT (Afrikans, Albanian, Amharic, Arabic, Bengali, Croatian,
+  Galician, Hebrew, Mandarin, Serbian, Tagalog, Urdu, Xhosa).
+
+### Changed
+
+- `PlayHTTTSService` uses the new v4 websocket API, which also fixes an issue
+  where text inputted to the TTS didn't return audio.
+
+- The default model for `ElevenLabsTTSService` is now `eleven_flash_v2_5`.
+
+- `OpenAIRealtimeBetaLLMService` now takes a `model` parameter in the
+  constructor.
+
+- Updated the default model for the `OpenAIRealtimeBetaLLMService`.
+
+- Room expiration (`exp`) in `DailyRoomProperties` is now optional (`None`) by
+  default instead of automatically setting a 5-minute expiration time. You must
+  explicitly set expiration time if desired.
+
+### Deprecated
+
+- `AWSTTSService` is now deprecated, use `PollyTTSService` instead.
+
+### Fixed
+
+- Fixed token counting in `GoogleLLMService`. Tokens were summed incorrectly
+  (double-counted in many cases).
+
+- Fixed an issue that could cause the bot to stop talking if there was a user
+  interruption before getting any audio from the TTS service.
+
+- Fixed an issue that would cause `ParallelPipeline` to handle `EndFrame`
+  incorrectly causing the main pipeline to not terminate or terminate too early.
+
+- Fixed an audio stuttering issue in `FastPitchTTSService`.
+
+- Fixed a `BaseOutputTransport` issue that was causing non-audio frames being
+  processed before the previous audio frames were played. This will allow, for
+  example, sending a frame `A` after a `TTSSpeakFrame` and the frame `A` will
+  only be pushed downstream after the audio generated from `TTSSpeakFrame` has
+  been spoken.
+
+- Fixed a `DeepgramSTTService` issue that was causing language to be passed as
+  an object instead of a string resulting in the connection to fail.
+
+## [0.0.51] - 2024-12-16
+
+### Fixed
+
+- Fixed an issue in websocket-based TTS services that was causing infinite
+  reconnections (Cartesia, ElevenLabs, PlayHT and LMNT).
+
+## [0.0.50] - 2024-12-11
+
+### Added
+
+- Added `GeminiMultimodalLiveLLMService`. This is an integration for Google's
+  Gemini Multimodal Live API, supporting:
+
+  - Real-time audio and video input processing
+  - Streaming text responses with TTS
+  - Audio transcription for both user and bot speech
+  - Function calling
+  - System instructions and context management
+  - Dynamic parameter updates (temperature, top_p, etc.)
+
+- Added `AudioTranscriber` utility class for handling audio transcription with
+  Gemini models.
+
+- Added new context classes for Gemini:
+
+  - `GeminiMultimodalLiveContext`
+  - `GeminiMultimodalLiveUserContextAggregator`
+  - `GeminiMultimodalLiveAssistantContextAggregator`
+  - `GeminiMultimodalLiveContextAggregatorPair`
+
+- Added new foundational examples for `GeminiMultimodalLiveLLMService`:
+
+  - `26-gemini-multimodal-live.py`
+  - `26a-gemini-multimodal-live-transcription.py`
+  - `26b-gemini-multimodal-live-video.py`
+  - `26c-gemini-multimodal-live-video.py`
+
+- Added `SimliVideoService`. This is an integration for Simli AI avatars.
+  (see https://www.simli.com)
+
+- Added NVIDIA Riva's `FastPitchTTSService` and `ParakeetSTTService`.
+  (see https://www.nvidia.com/en-us/ai-data-science/products/riva/)
+
+- Added `IdentityFilter`. This is the simplest frame filter that lets through
+  all incoming frames.
+
+- New `STTMuteStrategy` called `FUNCTION_CALL` which mutes the STT service
+  during LLM function calls.
+
+- `DeepgramSTTService` now exposes two event handlers `on_speech_started` and
+  `on_utterance_end` that could be used to implement interruptions. See new
+  example `examples/foundational/07c-interruptible-deepgram-vad.py`.
+
+- Added `GroqLLMService`, `GrokLLMService`, and `NimLLMService` for Groq, Grok,
+  and NVIDIA NIM API integration, with an OpenAI-compatible interface.
+
+- New examples demonstrating function calling with Groq, Grok, Azure OpenAI,
+  Fireworks, and NVIDIA NIM: `14f-function-calling-groq.py`,
+  `14g-function-calling-grok.py`, `14h-function-calling-azure.py`,
+  `14i-function-calling-fireworks.py`, and `14j-function-calling-nvidia.py`.
+
+- In order to obtain the audio stored by the `AudioBufferProcessor` you can now
+  also register an `on_audio_data` event handler. The `on_audio_data` handler
+  will be called every time `buffer_size` (a new constructor argument) is
+  reached. If `buffer_size` is 0 (default) you need to manually get the audio as
+  before using `AudioBufferProcessor.merge_audio_buffers()`.
+
+```
+@audiobuffer.event_handler("on_audio_data")
+async def on_audio_data(processor, audio, sample_rate, num_channels):
+    await save_audio(audio, sample_rate, num_channels)
+```
+
+- Added a new RTVI message called `disconnect-bot`, which when handled pushes
+  an `EndFrame` to trigger the pipeline to stop.
+
+### Changed
+
+- `STTMuteFilter` now supports multiple simultaneous muting strategies.
+
+- `XTTSService` language now defaults to `Language.EN`.
+
+- `SoundfileMixer` doesn't resample input files anymore to avoid startup
+  delays. The sample rate of the provided sound files now need to match the
+  sample rate of the output transport.
+
+- Input frames (audio, image and transport messages) are now system frames. This
+  means they are processed immediately by all processors instead of being queued
+  internally.
+
+- Expanded the transcriptions.language module to support a superset of
+  languages.
+
+- Updated STT and TTS services with language options that match the supported
+  languages for each service.
+
+- Updated the `AzureLLMService` to use the `OpenAILLMService`. Updated the
+  `api_version` to `2024-09-01-preview`.
+
+- Updated the `FireworksLLMService` to use the `OpenAILLMService`. Updated the
+  default model to `accounts/fireworks/models/firefunction-v2`.
+
+- Updated the `simple-chatbot` example to include a Javascript and React client
+  example, using RTVI JS and React.
+
+### Removed
+
+- Removed `AppFrame`. This was used as a special user custom frame, but there's
+  actually no use case for that.
+
+### Fixed
+
+- Fixed a `ParallelPipeline` issue that would cause system frames to be queued.
+
+- Fixed `FastAPIWebsocketTransport` so it can work with binary data (e.g. using
+  the protobuf serializer).
+
+- Fixed an issue in `CartesiaTTSService` that could cause previous audio to be
+  received after an interruption.
+
+- Fixed Cartesia, ElevenLabs, LMNT and PlayHT TTS websocket
+  reconnection. Before, if an error occurred no reconnection was happening.
+
+- Fixed a `BaseOutputTransport` issue that was causing audio to be discarded
+  after an `EndFrame` was received.
+
+- Fixed an issue in `WebsocketServerTransport` and `FastAPIWebsocketTransport`
+  that would cause a busy loop when using audio mixer.
+
+- Fixed a `DailyTransport` and `LiveKitTransport` issue where connections were
+  being closed in the input transport prematurely. This was causing frames
+  queued inside the pipeline being discarded.
+
+- Fixed an issue in `DailyTransport` that would cause some internal callbacks to
+  not be executed.
+
+- Fixed an issue where other frames were being processed while a `CancelFrame`
+  was being pushed down the pipeline.
+
+- `AudioBufferProcessor` now handles interruptions properly.
+
+- Fixed a `WebsocketServerTransport` issue that would prevent interruptions with
+  `TwilioSerializer` from working.
+
+- `DailyTransport.capture_participant_video` now allows capturing user's screen
+  share by simply passing `video_source="screenVideo"`.
+
+- Fixed Google Gemini message handling to properly convert appended messages to
+  Gemini's required format.
+
+- Fixed an issue with `FireworksLLMService` where chat completions were failing
+  by removing the `stream_options` from the chat completion options.
+
+## [0.0.49] - 2024-11-17
+
+### Added
+
+- Added RTVI `on_bot_started` event which is useful in a single turn
+  interaction.
+
+- Added `DailyTransport` events `dialin-connected`, `dialin-stopped`,
+  `dialin-error` and `dialin-warning`. Needs daily-python >= 0.13.0.
+
+- Added `RimeHttpTTSService` and the `07q-interruptible-rime.py` foundational
+  example.
+
+- Added `STTMuteFilter`, a general-purpose processor that combines STT
+  muting and interruption control. When active, it prevents both transcription
+  and interruptions during bot speech. The processor supports multiple
+  strategies: `FIRST_SPEECH` (mute only during bot's first
+  speech), `ALWAYS` (mute during all bot speech), or `CUSTOM` (using provided
+  callback).
+
+- Added `STTMuteFrame`, a control frame that enables/disables speech
+  transcription in STT services.
+
+## [0.0.48] - 2024-11-10 "Antonio release"
+
+### Added
+
+- There's now an input queue in each frame processor. When you call
+  `FrameProcessor.push_frame()` this will internally call
+  `FrameProcessor.queue_frame()` on the next processor (upstream or downstream)
+  and the frame will be internally queued (except system frames). Then, the
+  queued frames will get processed. With this input queue it is also possible
+  for FrameProcessors to block processing more frames by calling
+  `FrameProcessor.pause_processing_frames()`. The way to resume processing
+  frames is by calling `FrameProcessor.resume_processing_frames()`.
+
+- Added audio filter `NoisereduceFilter`.
+
+- Introduce input transport audio filters (`BaseAudioFilter`). Audio filters can
+  be used to remove background noises before audio is sent to VAD.
+
+- Introduce output transport audio mixers (`BaseAudioMixer`). Output transport
+  audio mixers can be used, for example, to add background sounds or any other
+  audio mixing functionality before the output audio is actually written to the
+  transport.
+
+- Added `GatedOpenAILLMContextAggregator`. This aggregator keeps the last
+  received OpenAI LLM context frame and it doesn't let it through until the
+  notifier is notified.
+
+- Added `WakeNotifierFilter`. This processor expects a list of frame types and
+  will execute a given callback predicate when a frame of any of those type is
+  being processed. If the callback returns true the notifier will be notified.
+
+- Added `NullFilter`. A null filter doesn't push any frames upstream or
+  downstream. This is usually used to disable one of the pipelines in
+  `ParallelPipeline`.
+
+- Added `EventNotifier`. This can be used as a very simple synchronization
+  feature between processors.
+
+- Added `TavusVideoService`. This is an integration for Tavus digital twins.
+  (see https://www.tavus.io/)
+
+- Added `DailyTransport.update_subscriptions()`. This allows you to have fine
+  grained control of what media subscriptions you want for each participant in a
+  room.
+
+- Added audio filter `KrispFilter`.
+
+### Changed
+
+- The following `DailyTransport` functions are now `async` which means they need
+  to be awaited: `start_dialout`, `stop_dialout`, `start_recording`,
+  `stop_recording`, `capture_participant_transcription` and
+  `capture_participant_video`.
+
+- Changed default output sample rate to 24000. This changes all TTS service to
+  output to 24000 and also the default output transport sample rate. This
+  improves audio quality at the cost of some extra bandwidth.
+
+- `AzureTTSService` now uses Azure websockets instead of HTTP requests.
+
+- The previous `AzureTTSService` HTTP implementation is now
+  `AzureHttpTTSService`.
+
+### Fixed
+
+- Websocket transports (FastAPI and Websocket) now synchronize with time before
+  sending data. This allows for interruptions to just work out of the box.
+
+- Improved bot speaking detection for all TTS services by using actual bot
+  audio.
+
+- Fixed an issue that was generating constant bot started/stopped speaking
+  frames for HTTP TTS services.
+
+- Fixed an issue that was causing stuttering with AWS TTS service.
+
+- Fixed an issue with PlayHTTTSService, where the TTFB metrics were reporting
+  very small time values.
+
+- Fixed an issue where AzureTTSService wasn't initializing the specified
+  language.
+
+### Other
+
+- Add `23-bot-background-sound.py` foundational example.
+
+- Added a new foundational example `22-natural-conversation.py`. This example
+  shows how to achieve a more natural conversation detecting when the user ends
+  statement.
+
+## [0.0.47] - 2024-10-22
+
+### Added
+
+- Added `AssemblyAISTTService` and corresponding foundational examples
+  `07o-interruptible-assemblyai.py` and `13d-assemblyai-transcription.py`.
+
+- Added a foundational example for Gladia transcription:
+  `13c-gladia-transcription.py`
+
+### Changed
+
+- Updated `GladiaSTTService` to use the V2 API.
+
+- Changed `DailyTransport` transcription model to `nova-2-general`.
+
+### Fixed
+
+- Fixed an issue that would cause an import error when importing
+  `SileroVADAnalyzer` from the old package `pipecat.vad.silero`.
+
+- Fixed `enable_usage_metrics` to control LLM/TTS usage metrics separately
+  from `enable_metrics`.
+
+## [0.0.46] - 2024-10-19
+
+### Added
+
+- Added `audio_passthrough` parameter to `STTService`. If enabled it allows
+  audio frames to be pushed downstream in case other processors need them.
+
+- Added input parameter options for `PlayHTTTSService` and
+  `PlayHTHttpTTSService`.
+
+### Changed
+
+- Changed `DeepgramSTTService` model to `nova-2-general`.
+
+- Moved `SileroVAD` audio processor to `processors.audio.vad`.
+
+- Module `utils.audio` is now `audio.utils`. A new `resample_audio` function has
+  been added.
+
+- `PlayHTTTSService` now uses PlayHT websockets instead of HTTP requests.
+
+- The previous `PlayHTTTSService` HTTP implementation is now
+  `PlayHTHttpTTSService`.
+
+- `PlayHTTTSService` and `PlayHTHttpTTSService` now use a `voice_engine` of
+  `PlayHT3.0-mini`, which allows for multi-lingual support.
+
+- Renamed `OpenAILLMServiceRealtimeBeta` to `OpenAIRealtimeBetaLLMService` to
+  match other services.
+
+### Deprecated
+
+- `LLMUserResponseAggregator` and `LLMAssistantResponseAggregator` are
+  mostly deprecated, use `OpenAILLMContext` instead.
+
+- The `vad` package is now deprecated and `audio.vad` should be used
+  instead. The `avd` package will get removed in a future release.
+
+### Fixed
+
+- Fixed an issue that would cause an error if no VAD analyzer was passed to
+  `LiveKitTransport` params.
+
+- Fixed `SileroVAD` processor to support interruptions properly.
+
+### Other
+
+- Added `examples/foundational/07-interruptible-vad.py`. This is the same as
+  `07-interruptible.py` but using the `SileroVAD` processor instead of passing
+  the `VADAnalyzer` in the transport.
+
+## [0.0.45] - 2024-10-16
+

+
+## Getting started
 
 You can get started with Pipecat running on your local machine, then move your agent processes to the cloud when you’re ready. You can also add a 📞 telephone number, 🖼️ image output, 📺 video input, use different LLMs, and more.
 
 ```shell
-# install the module
+# Install the module
 pip install pipecat-ai
 
-# set up an .env file with API keys
+# Set up your environment
 cp dot-env.template .env
 ```
 
-By default, in order to minimize dependencies, only the basic framework functionality is available. Some third-party AI services require additional dependencies that you can install with:
+To keep things lightweight, only the core framework is included by default. If you need support for third-party AI services, you can add the necessary dependencies with:
 
 ```shell
 pip install "pipecat-ai[option,...]"
 ```
 
-Your project may or may not need these, so they're made available as optional requirements. Here is a list:
+Available options include:
 
-- **AI services**: `anthropic`, `aws`, `azure`, `deepgram`, `gladia`, `google`, `fal`, `lmnt`, `moondream`, `openai`, `openpipe`, `playht`, `silero`, `whisper`, `xtts`
-- **Transports**: `local`, `websocket`, `daily`

+# Pipecat Documentation
+
+This directory contains the source files for auto-generating Pipecat's server API reference documentation.
+
+## Setup
+
+1. Install documentation dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+2. Make the build scripts executable:
+
+```bash
+chmod +x build-docs.sh rtd-test.py
+```
+
+## Building Documentation
+
+From this directory, you can build the documentation in several ways:
+
+### Local Build
+
+```bash
+# Using the build script (automatically opens docs when done)
+./build-docs.sh
+
+# Or directly with sphinx-build
+sphinx-build -b html . _build/html -W --keep-going
+```
+
+### ReadTheDocs Test Build
+
+To test the documentation build process exactly as it would run on ReadTheDocs:
+
+```bash
+./rtd-test.py
+```
+
+This script:
+
+- Creates a fresh virtual environment
+- Installs all dependencies as specified in requirements files
+- Handles conflicting dependencies (like grpcio versions for Riva and PlayHT)
+- Builds the documentation in an isolated environment
+- Provides detailed logging of the build process
+
+Use this script to verify your documentation will build correctly on ReadTheDocs before pushing changes.
+
+## Viewing Documentation
+
+The built documentation will be available at `_build/html/index.html`. To open:
+
+```bash
+# On MacOS
+open _build/html/index.html
+
+# On Linux
+xdg-open _build/html/index.html
+
+# On Windows
+start _build/html/index.html
+```
+
+## Directory Structure
+
+```

+├── api/            # Auto-generated API documentation
+├── _build/         # Built documentation
+├── _static/        # Static files (images, css, etc.)

+├── requirements-playht.txt  # PlayHT-specific dependencies
+├── build-docs.sh   # Local build script
+└── rtd-test.py     # ReadTheDocs test build script
+```
+
+## Notes
+
+- Documentation is auto-generated from Python docstrings
+- Service modules are automatically detected and included
+- The build process matches our ReadTheDocs configuration
+- Warnings are treated as errors (-W flag) to maintain consistency
+- The --keep-going flag ensures all errors are reported
+- Dependencies are split into multiple requirements files to handle version conflicts
+
+## Troubleshooting
+
+If you encounter missing service modules:
+
+1. Verify the service is installed with its extras: `pip install pipecat-ai[service-name]`
+2. Check the build logs for import errors
+3. Ensure the service module is properly initialized in the package
+4. Run `./rtd-test.py` to test in an isolated environment matching ReadTheDocs
+
+For dependency conflicts:
+
+1. Check the requirements files for version specifications
+2. Use `rtd-test.py` to verify dependency resolution
+3. Consider adding service-specific requirements files if needed

+# Understanding Different Frame Types in the Pipecat System
+
+In the Pipecat system, frames are used to represent different types of data and control signals that flow through the pipeline. Understanding these frame types is crucial for working with the system effectively. This tutorial will cover the main categories of frames and their specific uses.
+
+## 1. Base Frame Classes
+
+### Frame
+The `Frame` class is the base class for all frames. It includes:
+- `id`: A unique identifier
+- `name`: A descriptive name
+- `pts`: Presentation timestamp (optional)
+
+### DataFrame
+`DataFrame` is a subclass of `Frame` and serves as a base for most data-carrying frames.
+
+## 2. Audio Frames
+
+### AudioRawFrame
+Represents a chunk of audio with properties:
+- `audio`: Raw audio data
+- `sample_rate`: Audio sample rate
+- `num_channels`: Number of audio channels
+
+Subclasses include:
+- `InputAudioRawFrame`: For audio from input sources
+- `OutputAudioRawFrame`: For audio to be played by output devices
+- `TTSAudioRawFrame`: For audio generated by Text-to-Speech services
+
+## 3. Image Frames
+
+### ImageRawFrame
+Represents an image with properties:
+- `image`: Raw image data
+- `size`: Image dimensions
+- `format`: Image format (e.g., JPEG, PNG)
+
+Subclasses include:
+- `InputImageRawFrame`: For images from input sources
+- `OutputImageRawFrame`: For images to be displayed
+- `UserImageRawFrame`: For images associated with a specific user
+- `VisionImageRawFrame`: For images with associated text for description
+- `URLImageRawFrame`: For images with an associated URL
+
+### SpriteFrame
+Represents an animated sprite, containing a list of `ImageRawFrame` objects.
+
+## 4. Text and Transcription Frames
+
+### TextFrame
+Represents a chunk of text, used for various purposes in the pipeline.
+
+### TranscriptionFrame
+A specialized `TextFrame` for speech transcriptions, including:
+- `user_id`: ID of the speaking user
+- `timestamp`: When the transcription was generated
+- `language`: Detected language of the speech
+
+### InterimTranscriptionFrame
+Similar to `TranscriptionFrame`, but for interim (not final) transcriptions.
+
+## 5. LLM (Language Model) Frames
+
+### LLMMessagesFrame
+Contains a list of messages for an LLM service to process.
+
+### LLMMessagesAppendFrame and LLMMessagesUpdateFrame
+Used to modify the current context of LLM messages.
+
+### LLMSetToolsFrame
+Specifies tools (functions) available for the LLM to use.
+
+### LLMEnablePromptCachingFrame
+Controls prompt caching in certain LLMs.
+
+## 6. System and Control Frames
+
+### SystemFrame
+Base class for system-level frames.
+
+Important system frames include:
+- `StartFrame`: Initiates a pipeline
+- `CancelFrame`: Stops a pipeline immediately
+- `ErrorFrame`: Notifies of errors (with `FatalErrorFrame` for unrecoverable errors)
+- `EndTaskFrame` and `CancelTaskFrame`: Control pipeline tasks
+- `StartInterruptionFrame` and `StopInterruptionFrame`: Indicate user speech for interruptions
+
+### ControlFrame
+Base class for control-flow frames.
+
+Notable control frames:
+- `EndFrame`: Signals the end of a pipeline
+- `LLMFullResponseStartFrame` and `LLMFullResponseEndFrame`: Bracket LLM responses
+- `UserStartedSpeakingFrame` and `UserStoppedSpeakingFrame`: Indicate user speech activity
+- `BotStartedSpeakingFrame` and `BotStoppedSpeakingFrame`: Indicate bot speech activity
+- `TTSStartedFrame` and `TTSStoppedFrame`: Bracket Text-to-Speech responses
+
+## 7. Special Purpose Frames
+
+### MetricsFrame
+Contains performance metrics data.
+
+### FunctionCallInProgressFrame and FunctionCallResultFrame
+Used for handling LLM function (tool) calls.
+
+### ServiceUpdateSettingsFrame
+Base class for updating service settings, with specific subclasses for LLM, TTS, and STT services.
+
+## Conclusion
+
+Understanding these frame types is essential for working with the Pipecat system. Each frame type serves a specific purpose in the pipeline, whether it's carrying data (like audio or images), controlling the flow of the pipeline, or managing system-level operations. By using the appropriate frame types, you can effectively process and transmit various kinds of information through your pipeline.

-# Simple Chatbot
+# Chatbot with canonical-metrics
 
-<img src="image.png" width="420px">
+This project implements a chatbot using a pipeline architecture that integrates audio processing, transcription, and a language model for conversational interactions. The chatbot operates within a daily communication environment, utilizing various services for text-to-speech and language model responses.
 
-This app connects you to a chatbot powered by GPT-4, complete with animations generated by Stable Video Diffusion.
+## Features
 
-See a video of it in action: https://x.com/kwindla/status/1778628911817183509
+- **Audio Input and Output**: Captures microphone input and plays back audio responses.
+- **Voice Activity Detection**: Utilizes Silero VAD to manage audio input intelligently.
+- **Text-to-Speech**: Integrates ElevenLabs TTS service to convert text responses into audio.
+- **Language Model Interaction**: Uses OpenAI's GPT-4 model to generate responses based on user input.
+- **Transcription Services**: Captures and transcribes participant speech for analytics.
+- **Metrics Collection**: Sends audio data for analysis via Canonical Metrics Service.
+
+## Requirements
+
+- Python 3.10+
+- `python-dotenv`
+- Additional libraries from the `pipecat` package.
+
+## Setup
+
+1. Clone the repository.
+2. Install the required packages.
+3. Set up environment variables for API keys:
+   - `OPENAI_API_KEY`
+   - `ELEVENLABS_API_KEY`
+   - `CANONICAL_API_KEY`
+   - `CANONICAL_API_URL`
+4. Run the script.
+
+## Usage
+
+The chatbot introduces itself and engages in conversations, providing brief and creative responses. Designed for flexibility, it can support multiple languages with appropriate configuration.
+
+## Events
+
+- Participants joining or leaving the call are handled dynamically, adjusting the chatbot's behavior accordingly.
 
-And a quick video walkthrough of the code: https://www.loom.com/share/13df1967161f4d24ade054e7f8753416
 
 ℹ️ The first time, things might take extra time to get started since VAD (Voice Activity Detection) model needs to be downloaded.

+
+Barebones deployment example for [modal.com](https://www.modal.com)
+
+1. Install dependencies
+
+```bash
+python -m venv venv
+source venv/bin/active # or OS equivalent
+pip install -r requirements.txt
+```
+
+2. Setup .env
+
+```bash
+cp env.example .env
+```
+
+Alternatively, you can configure your Modal app to use [secrets](https://modal.com/docs/guide/secrets)
+
+3. Test the app locally
+
+```bash
+modal serve app.py
+```
+
+4. Deploy to production
+
+```bash
+modal deploy app.py
+```
+
+## Configuration options
+
+This app sets some sensible defaults for reducing cold starts, such as `minkeep_warm=1`, which will keep at least 1 warm instance ready for your bot function.
+
+It has been configured to only allow a concurrency of 1 (`max_inputs=1`) as each user will require their own running function.

+
+Your output will be converted to audio so don't include special characters in your answers.

+1. Transcribe exactly what the user said.
+2. Output the separator field '{marker}'.
+3. Respond to the user's input in a helpful, creative way using only simple text and punctuation.
