+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
-
-- 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`
-
-### Fixed
-
-- 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
-
-- 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
-
-### Changed
-
-- Metrics messages have moved out from the transport's base output into RTVI.
-
-## [0.0.44] - 2024-10-15
-
-### Added
-
-- Added support for OpenAI Realtime API with the new
-  `OpenAILLMServiceRealtimeBeta` processor.
-  (see https://platform.openai.com/docs/guides/realtime/overview)
-
-- Added `RTVIBotTranscriptionProcessor` which will send the RTVI
-  `bot-transcription` protocol message. These are TTS text aggregated (into
-  sentences) messages.
-
-- Added new input params to the `MarkdownTextFilter` utility. You can set
-  `filter_code` to filter code from text and `filter_tables` to filter tables
-  from text.
-
-- Added `CanonicalMetricsService`. This processor uses the new
-  `AudioBufferProcessor` to capture conversation audio and later send it to
-  Canonical AI.
-  (see https://canonical.chat/)
-
-- Added `AudioBufferProcessor`. This processor can be used to buffer mixed user and
-  bot audio. This can later be saved into an audio file or processed by some
-  audio analyzer.
-
-- Added `on_first_participant_joined` event to `LiveKitTransport`.
-
-### Changed
-
-- LLM text responses are now logged properly as unicode characters.
-
-- `UserStartedSpeakingFrame`, `UserStoppedSpeakingFrame`,
-  `BotStartedSpeakingFrame`, `BotStoppedSpeakingFrame`, `BotSpeakingFrame` and
-  `UserImageRequestFrame` are now based from `SystemFrame`
-
-### Fixed
-
-- Merge `RTVIBotLLMProcessor`/`RTVIBotLLMTextProcessor` and
-  `RTVIBotTTSProcessor`/`RTVIBotTTSTextProcessor` to avoid out of order issues.
-
-- Fixed an issue in RTVI protocol that could cause a `bot-llm-stopped` or
-  `bot-tts-stopped` message to be sent before a `bot-llm-text` or `bot-tts-text`
-  message.
-
-- Fixed `DeepgramSTTService` constructor settings not being merged with default
-  ones.
-
-- Fixed an issue in Daily transport that would cause tasks to be hanging if
-  urgent transport messages were being sent from a transport event handler.
-
-- Fixed an issue in `BaseOutputTransport` that would cause `EndFrame` to be
-  pushed downed too early and call `FrameProcessor.cleanup()` before letting the
-  transport stop properly.
-
-## [0.0.43] - 2024-10-10
-
-### Added
-
-- Added a new util called `MarkdownTextFilter` which is a subclass of a new
-  base class called `BaseTextFilter`. This is a configurable utility which
-  is intended to filter text received by TTS services.
-
-- Added new `RTVIUserLLMTextProcessor`. This processor will send an RTVI
-  `user-llm-text` message with the user content's that was sent to the LLM.
-
-### Changed
-
-- `TransportMessageFrame` doesn't have an `urgent` field anymore, instead
-  there's now a `TransportMessageUrgentFrame` which is a `SystemFrame` and
-  therefore skip all internal queuing.
-
-- For TTS services, convert inputted languages to match each service's language
-  format
-
-### Fixed
-
-- Fixed an issue where changing a language with the Deepgram STT service
-  wouldn't apply the change. This was fixed by disconnecting and reconnecting
-  when the language changes.
-
-## [0.0.42] - 2024-10-02
-
-### Added
-
-- `SentryMetrics` has been added to report frame processor metrics to
-  Sentry. This is now possible because `FrameProcessorMetrics` can now be passed
-  to `FrameProcessor`.
-
-- Added Google TTS service and corresponding foundational example
-  `07n-interruptible-google.py`
-
-- Added AWS Polly TTS support and `07m-interruptible-aws.py` as an example.
-
-- Added InputParams to Azure TTS service.
-
-- Added `LivekitTransport` (audio-only for now).
-
-- RTVI 0.2.0 is now supported.
-
-- All `FrameProcessors` can now register event handlers.
-
-```
-tts = SomeTTSService(...)
-
-@tts.event_handler("on_connected"):
-async def on_connected(processor):
-  ...
-```
-
-- Added `AsyncGeneratorProcessor`. This processor can be used together with a
-  `FrameSerializer` as an async generator. It provides a `generator()` function
-  that returns an `AsyncGenerator` and that yields serialized frames.
-
-- Added `EndTaskFrame` and `CancelTaskFrame`. These are new frames that are
-  meant to be pushed upstream to tell the pipeline task to stop nicely or
-  immediately respectively.
-
-- Added configurable LLM parameters (e.g., temperature, top_p, max_tokens, seed)
-  for OpenAI, Anthropic, and Together AI services along with corresponding
-  setter functions.
-
-- Added `sample_rate` as a constructor parameter for TTS services.
-
-- Pipecat has a pipeline-based architecture. The pipeline consists of frame
-  processors linked to each other. The elements traveling across the pipeline
-  are called frames.
-
-  To have a deterministic behavior the frames traveling through the pipeline
-  should always be ordered, except system frames which are out-of-band
-  frames. To achieve that, each frame processor should only output frames from a
-  single task.
-
-  In this version all the frame processors have their own task to push
-  frames. That is, when `push_frame()` is called the given frame will be put
-  into an internal queue (with the exception of system frames) and a frame
-  processor task will push it out.
-
-- Added pipeline clocks. A pipeline clock is used by the output transport to
-  know when a frame needs to be presented. For that, all frames now have an
-  optional `pts` field (prensentation timestamp). There's currently just one
-  clock implementation `SystemClock` and the `pts` field is currently only used
-  for `TextFrame`s (audio and image frames will be next).
-
-- A clock can now be specified to `PipelineTask` (defaults to
-  `SystemClock`). This clock will be passed to each frame processor via the
-  `StartFrame`.
-
-- Added `CartesiaHttpTTSService`.
-
-- `DailyTransport` now supports setting the audio bitrate to improve audio
-  quality through the `DailyParams.audio_out_bitrate` parameter. The new
-  default is 96kbps.
-
-- `DailyTransport` now uses the number of audio output channels (1 or 2) to set
-  mono or stereo audio when needed.
-
-- Interruptions support has been added to `TwilioFrameSerializer` when using
-  `FastAPIWebsocketTransport`.
-
-- Added new `LmntTTSService` text-to-speech service.
-  (see https://www.lmnt.com/)
-
-- Added `TTSModelUpdateFrame`, `TTSLanguageUpdateFrame`, `STTModelUpdateFrame`,
-  and `STTLanguageUpdateFrame` frames to allow you to switch models, language
-  and voices in TTS and STT services.
-
-- Added new `transcriptions.Language` enum.
-
-### Changed
-
-- Context frames are now pushed downstream from assistant context aggregators.
-
-- Removed Silero VAD torch dependency.
-
-- Updated individual update settings frame classes into a single
-  `ServiceUpdateSettingsFrame` class.
-
-- We now distinguish between input and output audio and image frames. We
-  introduce `InputAudioRawFrame`, `OutputAudioRawFrame`, `InputImageRawFrame`
-  and `OutputImageRawFrame` (and other subclasses of those). The input frames
-  usually come from an input transport and are meant to be processed inside the
-  pipeline to generate new frames. However, the input frames will not be sent
-  through an output transport. The output frames can also be processed by any
-  frame processor in the pipeline and they are allowed to be sent by the output
-  transport.
-
-- `ParallelTask` has been renamed to `SyncParallelPipeline`. A
-  `SyncParallelPipeline` is a frame processor that contains a list of different
-  pipelines to be executed concurrently. The difference between a
-  `SyncParallelPipeline` and a `ParallelPipeline` is that, given an input frame,
-  the `SyncParallelPipeline` will wait for all the internal pipelines to
-  complete. This is achieved by making sure the last processor in each of the
-  pipelines is synchronous (e.g. an HTTP-based service that waits for the
-  response).
-
-- `StartFrame` is back a system frame to make sure it's processed immediately by
-  all processors. `EndFrame` stays a control frame since it needs to be ordered
-  allowing the frames in the pipeline to be processed.
-
-- Updated `MoondreamService` revision to `2024-08-26`.
-
-- `CartesiaTTSService` and `ElevenLabsTTSService` now add presentation
-  timestamps to their text output. This allows the output transport to push the
-  text frames downstream at almost the same time the words are spoken. We say
-  "almost" because currently the audio frames don't have presentation timestamp
-  but they should be played at roughly the same time.
-
-- `DailyTransport.on_joined` event now returns the full session data instead of
-  just the participant.
-
-- `CartesiaTTSService` is now a subclass of `TTSService`.
-
-- `DeepgramSTTService` is now a subclass of `STTService`.
-
-- `WhisperSTTService` is now a subclass of `SegmentedSTTService`. A
-  `SegmentedSTTService` is a `STTService` where the provided audio is given in a
-  big chunk (i.e. from when the user starts speaking until the user stops
-  speaking) instead of a continous stream.
-
-### Fixed
-
-- Fixed OpenAI multiple function calls.
-
-- Fixed a Cartesia TTS issue that would cause audio to be truncated in some
-  cases.
-
-- Fixed a `BaseOutputTransport` issue that would stop audio and video rendering
-  tasks (after receiving and `EndFrame`) before the internal queue was emptied,
-  causing the pipeline to finish prematurely.
-
-- `StartFrame` should be the first frame every processor receives to avoid
-  situations where things are not initialized (because initialization happens on
-  `StartFrame`) and other frames come in resulting in undesired behavior.
-
-### Performance
-
-- `obj_id()` and `obj_count()` now use `itertools.count` avoiding the need of
-  `threading.Lock`.
-
-### Other
-
-- Pipecat now uses Ruff as its formatter (https://github.com/astral-sh/ruff).
-
-## [0.0.41] - 2024-08-22
-
-### Added
-
-- Added `LivekitFrameSerializer` audio frame serializer.
-
-### Fixed
-
-- Fix `FastAPIWebsocketOutputTransport` variable name clash with subclass.
-
-- Fix an `AnthropicLLMService` issue with empty arguments in function calling.
-
-### Other
-
-- Fixed `studypal` example errors.
-
-## [0.0.40] - 2024-08-20
-
-### Added
-
-- VAD parameters can now be dynamicallt updated using the
-  `VADParamsUpdateFrame`.
-
-- `ErrorFrame` has now a `fatal` field to indicate the bot should exit if a
-  fatal error is pushed upstream (false by default). A new `FatalErrorFrame`
-  that sets this flag to true has been added.
-
-- `AnthropicLLMService` now supports function calling and initial support for
-  prompt caching.
-  (see https://www.anthropic.com/news/prompt-caching)
-
-- `ElevenLabsTTSService` can now specify ElevenLabs input parameters such as
-  `output_format`.
-
-- `TwilioFrameSerializer` can now specify Twilio's and Pipecat's desired sample
-  rates to use.
-
-- Added new `on_participant_updated` event to `DailyTransport`.
-
-- Added `DailyRESTHelper.delete_room_by_name()` and
-  `DailyRESTHelper.delete_room_by_url()`.
-
-- Added LLM and TTS usage metrics. Those are enabled when
-  `PipelineParams.enable_usage_metrics` is True.
-
-- `AudioRawFrame`s are now pushed downstream from the base output
-  transport. This allows capturing the exact words the bot says by adding an STT
-  service at the end of the pipeline.
-
-- Added new `GStreamerPipelineSource`. This processor can generate image or
-  audio frames from a GStreamer pipeline (e.g. reading an MP4 file, and RTP
-  stream or anything supported by GStreamer).
-
-- Added `TransportParams.audio_out_is_live`. This flag is False by default and
-  it is useful to indicate we should not synchronize audio with sporadic images.
-
-- Added new `BotStartedSpeakingFrame` and `BotStoppedSpeakingFrame` control
-  frames. These frames are pushed upstream and they should wrap
-  `BotSpeakingFrame`.
-
-- Transports now allow you to register event handlers without decorators.
-
-### Changed
-
-- Support RTVI message protocol 0.1. This includes new messages, support for
-  messages responses, support for actions, configuration, webhooks and a bunch
-  of new cool stuff.
-  (see https://docs.rtvi.ai/)
-
-- `SileroVAD` dependency is now imported via pip's `silero-vad` package.
-
-- `ElevenLabsTTSService` now uses `eleven_turbo_v2_5` model by default.
-
-- `BotSpeakingFrame` is now a control frame.
-
-- `StartFrame` is now a control frame similar to `EndFrame`.
-
-- `DeepgramTTSService` now is more customizable. You can adjust the encoding and
-  sample rate.
-
-### Fixed
-
-- `TTSStartFrame` and `TTSStopFrame` are now sent when TTS really starts and
-  stops. This allows for knowing when the bot starts and stops speaking even
-  with asynchronous services (like Cartesia).
-
-- Fixed `AzureSTTService` transcription frame timestamps.
-
-- Fixed an issue with `DailyRESTHelper.create_room()` expirations which would
-  cause this function to stop working after the initial expiration elapsed.
-
-- Improved `EndFrame` and `CancelFrame` handling. `EndFrame` should end things
-  gracefully while a `CancelFrame` should cancel all running tasks as soon as
-  possible.
-
-- Fixed an issue in `AIService` that would cause a yielded `None` value to be
-  processed.
-
-- RTVI's `bot-ready` message is now sent when the RTVI pipeline is ready and
-  a first participant joins.
-
-- Fixed a `BaseInputTransport` issue that was causing incoming system frames to
-  be queued instead of being pushed immediately.
-
-- Fixed a `BaseInputTransport` issue that was causing start/stop interruptions
-  incoming frames to not cancel tasks and be processed properly.
-
-### Other
-
-- Added `studypal` example (from to the Cartesia folks!).
-
-- Most examples now use Cartesia.
-
-- Added examples `foundational/19a-tools-anthropic.py`,
-  `foundational/19b-tools-video-anthropic.py` and
-  `foundational/19a-tools-togetherai.py`.
-
-- Added examples `foundational/18-gstreamer-filesrc.py` and
-  `foundational/18a-gstreamer-videotestsrc.py` that show how to use
-  `GStreamerPipelineSource`
-
-- Remove `requests` library usage.
-
-- Cleanup examples and use `DailyRESTHelper`.
-
-## [0.0.39] - 2024-07-23
-
-### Fixed
-
-- Fixed a regression introduced in 0.0.38 that would cause Daily transcription
-  to stop the Pipeline.
-
-## [0.0.38] - 2024-07-23
-
-### Added
-
-- Added `force_reload`, `skip_validation` and `trust_repo` to `SileroVAD` and
-  `SileroVADAnalyzer`. This allows caching and various GitHub repo validations.
-
-- Added `send_initial_empty_metrics` flag to `PipelineParams` to request for
-  initial empty metrics (zero values). True by default.
-
-### Fixed
-
-- Fixed initial metrics format. It was using the wrong keys name/time instead of
-  processor/value.
-
-- STT services should be using ISO 8601 time format for transcription frames.
-
-- Fixed an issue that would cause Daily transport to show a stop transcription
-  error when actually none occurred.
-
-## [0.0.37] - 2024-07-22
-
-### Added
-
-- Added `RTVIProcessor` which implements the RTVI-AI standard.
-  See https://github.com/rtvi-ai
-
-- Added `BotInterruptionFrame` which allows interrupting the bot while talking.
-
-- Added `LLMMessagesAppendFrame` which allows appending messages to the current
-  LLM context.
-
-- Added `LLMMessagesUpdateFrame` which allows changing the LLM context for the
-  one provided in this new frame.
-
-- Added `LLMModelUpdateFrame` which allows updating the LLM model.
-
-- Added `TTSSpeakFrame` which causes the bot say some text. This text will not
-  be part of the LLM context.
-
-- Added `TTSVoiceUpdateFrame` which allows updating the TTS voice.
-
-### Removed
-
-- We remove the `LLMResponseStartFrame` and `LLMResponseEndFrame` frames. These
-  were added in the past to properly handle interruptions for the
-  `LLMAssistantContextAggregator`. But the `LLMContextAggregator` is now based
-  on `LLMResponseAggregator` which handles interruptions properly by just
-  processing the `StartInterruptionFrame`, so there's no need for these extra
-  frames any more.
-
-### Fixed
-
-- Fixed an issue with `StatelessTextTransformer` where it was pushing a string
-  instead of a `TextFrame`.
-
-- `TTSService` end of sentence detection has been improved. It now works with
-  acronyms, numbers, hours and others.
-
-- Fixed an issue in `TTSService` that would not properly flush the current
-  aggregated sentence if an `LLMFullResponseEndFrame` was found.
-
-### Performance
-
-- `CartesiaTTSService` now uses websockets which improves speed. It also
-  leverages the new Cartesia contexts which maintains generated audio prosody
-  when multiple inputs are sent, therefore improving audio quality a lot.
-
-## [0.0.36] - 2024-07-02
-
-### Added
-
-- Added `GladiaSTTService`.
-  See https://docs.gladia.io/chapters/speech-to-text-api/pages/live-speech-recognition
-
-- Added `XTTSService`. This is a local Text-To-Speech service.
-  See https://github.com/coqui-ai/TTS
-
-- Added `UserIdleProcessor`. This processor can be used to wait for any
-  interaction with the user. If the user doesn't say anything within a given
-  timeout a provided callback is called.
-
-- Added `IdleFrameProcessor`. This processor can be used to wait for frames
-  within a given timeout. If no frame is received within the timeout a provided
-  callback is called.
-
-- Added new frame `BotSpeakingFrame`. This frame will be continuously pushed
-  upstream while the bot is talking.
-
-- It is now possible to specify a Silero VAD version when using `SileroVADAnalyzer`
-  or `SileroVAD`.
-
-- Added `AysncFrameProcessor` and `AsyncAIService`. Some services like
-  `DeepgramSTTService` need to process things asynchronously. For example, audio
-  is sent to Deepgram but transcriptions are not returned immediately. In these
-  cases we still require all frames (except system frames) to be pushed
-  downstream from a single task. That's what `AsyncFrameProcessor` is for. It
-  creates a task and all frames should be pushed from that task. So, whenever a
-  new Deepgram transcription is ready that transcription will also be pushed
-  from this internal task.
-
-- The `MetricsFrame` now includes processing metrics if metrics are enabled. The
-  processing metrics indicate the time a processor needs to generate all its
-  output. Note that not all processors generate these kind of metrics.
-
-### Changed
-
-- `WhisperSTTService` model can now also be a string.
-
-- Added missing \* keyword separators in services.
-
-### Fixed
-
-- `WebsocketServerTransport` doesn't try to send frames anymore if serializers
-  returns `None`.
-
-- Fixed an issue where exceptions that occurred inside frame processors were
-  being swallowed and not displayed.
-
-- Fixed an issue in `FastAPIWebsocketTransport` where it would still try to send
-  data to the websocket after being closed.
-
-### Other
-
-- Added Fly.io deployment example in `examples/deployment/flyio-example`.
-
-- Added new `17-detect-user-idle.py` example that shows how to use the new
-  `UserIdleProcessor`.
-

-
-### Changed
-
-- `FastAPIWebsocketParams` now require a serializer.

-  8000 sample rate.
-

-### Fixed
-
-- Fixed an issue with asynchronous STT services (Deepgram and Azure) that could
-  interruptions to ignore transcriptions.
-
-- Fixed an issue introduced in 0.0.33 that would cause the LLM to generate
-  shorter output.
-
-## [0.0.33] - 2024-06-25
-
-### Changed
-
-- Upgraded to Cartesia's new Python library 1.0.0. `CartesiaTTSService` now
-  expects a voice ID instead of a voice name (you can get the voice ID from
-  Cartesia's playground). You can also specify the audio `sample_rate` and
-  `encoding` instead of the previous `output_format`.
-
-### Fixed
-
-- Fixed an issue with asynchronous STT services (Deepgram and Azure) that could
-  cause static audio issues and interruptions to not work properly when dealing
-  with multiple LLMs sentences.
-
-- Fixed an issue that could mix new LLM responses with previous ones when
-  handling interruptions.
-
-- Fixed a Daily transport blocking situation that occurred while reading audio
-  frames after a participant left the room. Needs daily-python >= 0.10.1.

-# Simple Chatbot
-
-<img src="image.png" width="420px">
-
-This app connects you to a chatbot powered by GPT-4, complete with animations generated by Stable Video Diffusion.
-
-See a video of it in action: https://x.com/kwindla/status/1778628911817183509
-
-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.
-
-## Get started
-
-```python
-python3 -m venv venv
-source venv/bin/activate
-pip install -r requirements.txt
-
-cp env.example .env # and add your credentials
-
-```
-
-## Run the server
-
-```bash
-python server.py
-```
-
-Then, visit `http://localhost:7860/` in your browser to start a chatbot session.
-
-## Build and test the Docker image
-
-```
-docker build -t chatbot .
-docker run --env-file .env -p 7860:7860 chatbot
-```

-# Fly.io deployment example
-
-This project modifies the `bot_runner.py` server to launch a new machine for each user session. This is a recommended approach for production vs. running shell processess as your deployment will quickly run out of system resources under load.
-
-For this example, we are using Daily as a WebRTC transport and provisioning a new room and token for each session. You can use another transport, such as WebSockets, by modifying the `bot.py` and `bot_runner.py` files accordingly.
-
-## Setting up your fly.io deployment
-
-### Create your fly.toml file
-
-You can copy the `example-fly.toml` as a reference. Be sure to change the app name to something unique.
-
-### Create your .env file
-
-Copy the base `env.example` to `.env` and enter the necessary API keys.
-
-`FLY_APP_NAME` should match that in the `fly.toml` file.
-
-### Launch a new fly.io project
-
-`fly launch` or `fly launch --org your-org-name`
-
-### Set the necessary app secrets from your .env
-
-Note: you can do this manually via the fly.io dashboard under the "secrets" sub-section of your deployment (e.g. "https://fly.io/apps/fly-app-name/secrets") or run the following terminal command:
-
-`cat .env | tr '\n' ' ' | xargs flyctl secrets set`
-
-### Deploy your machine
-
-`fly deploy`
-
-## Connecting to your bot
-
-Send a post request to your running fly.io instance:
-
-`curl --location --request POST 'https://YOUR_FLY_APP_NAME/'`
-
-This request will wait until the machine enters into a `starting` state, before returning the a room URL and token to join.
