CHANGELOG.md

@@ -9,641 +9,6 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ### Added
 
-- 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.
-
-- 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
-
-- Updated individual update settings frame classes into a single UpdateSettingsFrame
-  class for STT, LLM, and TTS.
-
-- 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 so we 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 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`.
-
-## [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`.
-
-## [0.0.35] - 2024-06-28
-
-### Changed
-
-- `FastAPIWebsocketParams` now require a serializer.
-
-- `TwilioFrameSerializer` now requires a `streamSid`.
-
-### Fixed
-
-- Silero VAD number of frames needs to be 512 for 16000 sample rate or 256 for
-  8000 sample rate.
-
-## [0.0.34] - 2024-06-25
-
-### 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.
-
-## [0.0.32] - 2024-06-22
-
-### Added
-
-- Allow specifying a `DeepgramSTTService` url which allows using on-prem
-  Deepgram.
-
-- Added new `FastAPIWebsocketTransport`. This is a new websocket transport that
-  can be integrated with FastAPI websockets.
-
-- Added new `TwilioFrameSerializer`. This is a new serializer that knows how to
-  serialize and deserialize audio frames from Twilio.
-
-- Added Daily transport event: `on_dialout_answered`. See
-  https://reference-python.daily.co/api_reference.html#daily.EventHandler
-
-- Added new `AzureSTTService`. This allows you to use Azure Speech-To-Text.
-
-### Performance
-
-- Convert `BaseOutputTransport` and `BaseOutputTransport` to fully use asyncio
-  and remove the use of threads.
-
-### Other
-
-- Added `twilio-chatbot`. This is an example that shows how to integrate Twilio
-  phone numbers with a Pipecat bot.
-
-- Updated `07f-interruptible-azure.py` to use `AzureLLMService`,
-  `AzureSTTService` and `AzureTTSService`.
-
-## [0.0.31] - 2024-06-13
-
-### Performance
-
-- Break long audio frames into 20ms chunks instead of 10ms.
-
-## [0.0.30] - 2024-06-13
-
-### Added
-
-- Added `report_only_initial_ttfb` to `PipelineParams`. This will make it so
-  only the initial TTFB metrics after the user stops talking are reported.
-
-- Added `OpenPipeLLMService`. This service will let you run OpenAI through
-  OpenPipe's SDK.
-
-- Allow specifying frame processors' name through a new `name` constructor
-  argument.
-
-- Added `DeepgramSTTService`. This service has an ongoing websocket
-  connection. To handle this, it subclasses `AIService` instead of
-  `STTService`. The output of this service will be pushed from the same task,
-  except system frames like `StartFrame`, `CancelFrame` or
-  `StartInterruptionFrame`.
-
-### Changed
-
-- `FrameSerializer.deserialize()` can now return `None` in case it is not
-  possible to desearialize the given data.
-
-- `daily_rest.DailyRoomProperties` now allows extra unknown parameters.
-
-### Fixed
-
-- Fixed an issue where `DailyRoomProperties.exp` always had the same old
-  timestamp unless set by the user.
-
-- Fixed a couple of issues with `WebsocketServerTransport`. It needed to use
-  `push_audio_frame()` and also VAD was not working properly.
-
-- Fixed an issue that would cause LLM aggregator to fail with small
-  `VADParams.stop_secs` values.
-
-- Fixed an issue where `BaseOutputTransport` would send longer audio frames
-  preventing interruptions.
-
-### Other
-
-- Added new `07h-interruptible-openpipe.py` example. This example shows how to
-  use OpenPipe to run OpenAI LLMs and get the logs stored in OpenPipe.
-
-- Added new `dialin-chatbot` example. This examples shows how to call the bot
-  using a phone number.
-
-## [0.0.29] - 2024-06-07
-
-### Added
-
-- Added a new `FunctionFilter`. This filter will let you filter frames based on
-  a given function, except system messages which should never be filtered.
-
-- Added `FrameProcessor.can_generate_metrics()` method to indicate if a
-  processor can generate metrics. In the future this might get an extra argument
-  to ask for a specific type of metric.
-
-- Added `BasePipeline`. All pipeline classes should be based on this class. All
-  subclasses should implement a `processors_with_metrics()` method that returns
-  a list of all `FrameProcessor`s in the pipeline that can generate metrics.
-
-- Added `enable_metrics` to `PipelineParams`.
-
-- Added `MetricsFrame`. The `MetricsFrame` will report different metrics in the
-  system. Right now, it can report TTFB (Time To First Byte) values for
-  different services, that is the time spent between the arrival of a `Frame` to
-  the processor/service until the first `DataFrame` is pushed downstream. If
-  metrics are enabled an intial `MetricsFrame` with all the services in the
-  pipeline will be sent.
-
-- Added TTFB metrics and debug logging for TTS services.
-
-### Changed
-
-- Moved `ParallelTask` to `pipecat.pipeline.parallel_task`.
-
-### Fixed
-
-- Fixed PlayHT TTS service to work properly async.
-
-## [0.0.28] - 2024-06-05
-
-### Fixed
-
-- Fixed an issue with `SileroVADAnalyzer` that would cause memory to keep
-  growing indefinitely.
-
-## [0.0.27] - 2024-06-05
-
-### Added
-
-- Added `DailyTransport.participants()` and `DailyTransport.participant_counts()`.
-
-## [0.0.26] - 2024-06-05
-
-### Added
-
-- Added `OpenAITTSService`.
-
-- Allow passing `output_format` and `model_id` to `CartesiaTTSService` to change
-  audio sample format and the model to use.
-
-- Added `DailyRESTHelper` which helps you create Daily rooms and tokens in an
-  easy way.
-
-- `PipelineTask` now has a `has_finished()` method to indicate if the task has
-  completed. If a task is never ran `has_finished()` will return False.
-
-- `PipelineRunner` now supports SIGTERM. If received, the runner will be
-  canceled.
-
-### Fixed
-
-- Fixed an issue where `BaseInputTransport` and `BaseOutputTransport` where
-  stopping push tasks before pushing `EndFrame` frames could cause the bots to
-  get stuck.
-
-- Fixed an error closing local audio transports.
-
-- Fixed an issue with Deepgram TTS that was introduced in the previous release.
-
-- Fixed `AnthropicLLMService` interruptions. If an interruption occurred, a
-  `user` message could be appended after the previous `user` message. Anthropic
-  does not allow that because it requires alternate `user` and `assistant`
-  messages.
-
-### Performance
-
-- The `BaseInputTransport` does not pull audio frames from sub-classes any
-  more. Instead, sub-classes now push audio frames into a queue in the base
-  class. Also, `DailyInputTransport` now pushes audio frames every 20ms instead
-  of 10ms.
-
-- Remove redundant camera input thread from `DailyInputTransport`. This should
-  improve performance a little bit when processing participant videos.
-
-- Load Cartesia voice on startup.
-
-## [0.0.25] - 2024-05-31
-
-### Added
-
-- Added WebsocketServerTransport. This will create a websocket server and will
-  read messages coming from a client. The messages are serialized/deserialized
-  with protobufs. See `examples/websocket-server` for a detailed example.
-
-- Added function calling (LLMService.register_function()). This will allow the
-  LLM to call functions you have registered when needed. For example, if you
-  register a function to get the weather in Los Angeles and ask the LLM about
-  the weather in Los Angeles, the LLM will call your function.
-  See https://platform.openai.com/docs/guides/function-calling
-
-- Added new `LangchainProcessor`.
-
 - Added Cartesia TTS support (https://cartesia.ai/)

-# 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/start_bot'`
-
-This request will wait until the machine enters into a `starting` state, before returning the a room URL and token to join.

-# Dialin example
-
-Example project that demonstrates how to add phone number dialin to your Pipecat bots. We include examples for both Daily (`bot_daily.py`) and Twilio (`bot_twilio.py`), depending on who you want to use as a phone vendor.
-
-- 🔁 Transport: Daily WebRTC
-- 💬 Speech-to-Text: Deepgram via Daily transport
-- 🤖 LLM: GPT4-o / OpenAI
-- 🔉 Text-to-Speech: ElevenLabs
-
-#### Should I use Daily or Twilio as a vendor?
-
-If you're starting from scratch, using Daily to provision phone numbers alongside Daily as a transport offers some convenience (such as automatic call forwarding.)
-
-If you already have Twilio numbers and workflows that you want to connect to your Pipecat bots, there is some additional configuration required (you'll need to create a `on_dialin_ready` and use the Twilio client to trigger the forward.)
-
-You can read more about this, as well as see respective walkthroughs in our docs.
-
-## Setup
-
-```shell
-# Install the requirements
-pip install -r requirements.txt
-
-# Setup your env
-mv env.example .env
-```
-
-## Using Daily numbers
-
-Run `bot_runner.py` to handle incoming HTTP requests:
-
-`python bot_runner.py --host localhost`
-
-Then target the following URL:
-
-`POST /daily_start_bot`
-
-For more configuration options, please consult Daily's API documentation.
-
-
-## Using Twilio numbers
-
-As above, but target the following URL:
-
-`POST /twilio_start_bot`
-
-For more configuration options, please consult Twilio's API documentation.
-
-## Deployment example
-
-A Dockerfile is included in this demo for convenience. Here is an example of how to build and deploy your bot to [fly.io](https://fly.io).
-
-*Please note: This demo spawns agents as subprocesses for convenience / demonstration purposes. You would likely not want to do this in production as it would limit concurrency to available system resources. For more information on how to deploy your bots using VMs, refer to the Pipecat documentation.*
-
-### Build the docker image
-
-`docker build -t tag:project .`
-
-### Launch the fly project
-
-`mv fly.example.toml fly.toml`
-
-`fly launch` (using the included fly.toml)
-
-### Setup your secrets on Fly
-
-Set the necessary secrets (found in `env.example`)
-
-`fly secrets set DAILY_API_KEY=... OPENAI_API_KEY=... ELEVENLABS_API_KEY=... ELEVENLABS_VOICE_ID=...`
-
-If you're using Twilio as a number vendor:
-
-`fly secrets set TWILIO_ACCOUNT_SID=... TWILIO_AUTH_TOKEN=...`
-
-### Deploy!
-
-`fly deploy`
-
-## Need to do something more advanced?
-
-This demo covers the basics of bot telephony. If you want to know more about working with PSTN / SIP, please ping us on [Discord](https://discord.gg/pipecat).
