CHANGELOG.md

@@ -5,6 +5,156 @@ 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

+# 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
+```

-This app connects you to a chatbot powered by GPT-4, complete with animations generated by Stable Video Diffusion.
+This project implements an AI-powered chatbot designed to streamline the medical intake process for Tri-County Health Services. The chatbot, named Jessica, interacts with patients to collect essential information before their doctor's visit, enhancing efficiency and improving the patient experience.
 
-See a video of it in action: https://x.com/kwindla/status/1778628911817183509
+## Features
 
-And a quick video walkthrough of the code: https://www.loom.com/share/13df1967161f4d24ade054e7f8753416
+Identity Verification: Confirms patient identity by verifying their date of birth.
+Prescription Information: Collects details about current medications and dosages.
+Allergy Documentation: Records patient allergies.
+Medical Conditions: Gathers information about existing medical conditions.
+Reason for Visit: Asks patients about the purpose of their current doctor's visit.
+
+## Technical Stack
+
+Language: Python
+AI Model: OpenAI's GPT-4
+Text-to-Speech: Cartesia TTS Service
+Audio Processing: Silero VAD (Voice Activity Detection)
+Real-time Communication: Daily.co API
+
+## Key Components
+
+IntakeProcessor: Manages the conversation flow and information gathering process.
+DailyTransport: Handles real-time audio communication.
+CartesiaTTSService: Converts text responses to speech.
+OpenAILLMService: Processes natural language and generates appropriate responses.
+Pipeline: Orchestrates the flow of information between different components.
+
+How It Works
+
+The chatbot introduces itself and verifies the patient's identity.
+It systematically collects information about prescriptions, allergies, medical conditions, and the reason for the visit.
+The conversation is guided by a series of function calls that transition between different stages of the intake process.
+All collected information is logged for later use by medical professionals.
 
 ℹ️ The first time, things might take extra time to get started since VAD (Voice Activity Detection) model needs to be downloaded.
