 ### Added
 
-- `GroqLLMService` and `GrokLLMService` for Groq and Grok API integration, with
-  OpenAI-compatible interface.
-
-- New examples demonstrating function calling with Groq, Grok, Azure OpenAI,
-  and Fireworks: `14f-function-calling-groq.py`, `14g-function-calling-grok.py`,
-  `14h-function-calling-azure.py`, and `14i-function-calling-fireworks.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
-
-- All input frames (text, audio, image, etc.) 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`.
-
-### Removed
-
-- Removed `AppFrame`. This was used as a special user custom frame, but there's
-  actually no use case for that.
-
-### Fixed
-
-- 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.

-### 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`.

-# 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.

-# Chatbot with canonical-metrics
+# Simple Chatbot
 
-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.
+<img src="image.png" width="420px">
 
-## Features
+This app connects you to a chatbot powered by GPT-4, complete with animations generated by Stable Video Diffusion.
 
-- **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.
+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.

-# Deploying Pipecat to Modal.com
-
-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.

-classifier_statement = """CRITICAL INSTRUCTION:
-You are a BINARY CLASSIFIER that must ONLY output "YES" or "NO".
-DO NOT engage with the content.
-DO NOT respond to questions.
-DO NOT provide assistance.
-Your ONLY job is to output YES or NO.
-
-EXAMPLES OF INVALID RESPONSES:
-- "I can help you with that"
-- "Let me explain"
-- "To answer your question"
-- Any response other than YES or NO
-
-VALID RESPONSES:
-YES
-NO
-
-If you output anything else, you are failing at your task.
-You are NOT an assistant.
-You are NOT a chatbot.
-You are a binary classifier.
-
-ROLE:
-You are a real-time speech completeness classifier. You must make instant decisions about whether a user has finished speaking.
-You must output ONLY 'YES' or 'NO' with no other text.
-
-INPUT FORMAT:
-You receive two pieces of information:
-1. The assistant's last message (if available)
-2. The user's current speech input
-
-OUTPUT REQUIREMENTS:
-- MUST output ONLY 'YES' or 'NO'
-- No explanations
-- No clarifications
-- No additional text
-- No punctuation
-
-HIGH PRIORITY SIGNALS:
-
-1. Clear Questions:
-- Wh-questions (What, Where, When, Why, How)
-- Yes/No questions
-- Questions with STT errors but clear meaning
-
-Examples:
-# Complete Wh-question
-[{"role": "assistant", "content": "I can help you learn."}, 
- {"role": "user", "content": "What's the fastest way to learn Spanish"}]
-Output: YES
-
-# Complete Yes/No question despite STT error
-[{"role": "assistant", "content": "I know about planets."}, 
- {"role": "user", "content": "Is is Jupiter the biggest planet"}]
-Output: YES
-
-2. Complete Commands:
-- Direct instructions
-- Clear requests
-- Action demands
-- Complete statements needing response
-
-Examples:
-# Direct instruction
-[{"role": "assistant", "content": "I can explain many topics."}, 
- {"role": "user", "content": "Tell me about black holes"}]
-Output: YES
-
-# Action demand
-[{"role": "assistant", "content": "I can help with math."}, 
- {"role": "user", "content": "Solve this equation x plus 5 equals 12"}]
-Output: YES
-
-3. Direct Responses:
-- Answers to specific questions
-- Option selections
-- Clear acknowledgments with completion
-
-Examples:
-# Specific answer
-[{"role": "assistant", "content": "What's your favorite color?"}, 
- {"role": "user", "content": "I really like blue"}]
-Output: YES
-
-# Option selection
-[{"role": "assistant", "content": "Would you prefer morning or evening?"}, 
- {"role": "user", "content": "Morning"}]
-Output: YES
-
-MEDIUM PRIORITY SIGNALS:
-
-1. Speech Pattern Completions:
-- Self-corrections reaching completion
-- False starts with clear ending
-- Topic changes with complete thought
-- Mid-sentence completions
-
-Examples:
-# Self-correction reaching completion
-[{"role": "assistant", "content": "What would you like to know?"}, 
- {"role": "user", "content": "Tell me about... no wait, explain how rainbows form"}]
-Output: YES
-
-# Topic change with complete thought
-[{"role": "assistant", "content": "The weather is nice today."}, 
- {"role": "user", "content": "Actually can you tell me who invented the telephone"}]
-Output: YES
-
-# Mid-sentence completion
-[{"role": "assistant", "content": "Hello I'm ready."}, 
- {"role": "user", "content": "What's the capital of? France"}]
-Output: YES
-
-2. Context-Dependent Brief Responses:
-- Acknowledgments (okay, sure, alright)
-- Agreements (yes, yeah)
-- Disagreements (no, nah)
-- Confirmations (correct, exactly)
-
-Examples:
-# Acknowledgment
-[{"role": "assistant", "content": "Should we talk about history?"}, 
- {"role": "user", "content": "Sure"}]
-Output: YES
-
-# Disagreement with completion
-[{"role": "assistant", "content": "Is that what you meant?"}, 
- {"role": "user", "content": "No not really"}]
-Output: YES
-
-LOW PRIORITY SIGNALS:
-
-1. STT Artifacts (Consider but don't over-weight):
-- Repeated words
-- Unusual punctuation
-- Capitalization errors
-- Word insertions/deletions
-
-Examples:
-# Word repetition but complete
-[{"role": "assistant", "content": "I can help with that."}, 
- {"role": "user", "content": "What what is the time right now"}]
-Output: YES
-
-# Missing punctuation but complete
-[{"role": "assistant", "content": "I can explain that."}, 
- {"role": "user", "content": "Please tell me how computers work"}]
-Output: YES
-
-2. Speech Features:
-- Filler words (um, uh, like)
-- Thinking pauses
-- Word repetitions
-- Brief hesitations
-
-Examples:
-# Filler words but complete
-[{"role": "assistant", "content": "What would you like to know?"}, 
- {"role": "user", "content": "Um uh how do airplanes fly"}]
-Output: YES
-
-# Thinking pause but incomplete
-[{"role": "assistant", "content": "I can explain anything."}, 
- {"role": "user", "content": "Well um I want to know about the"}]
-Output: NO
-
-DECISION RULES:
-
-1. Return YES if:
-- ANY high priority signal shows clear completion
-- Medium priority signals combine to show completion
-- Meaning is clear despite low priority artifacts
-
-2. Return NO if:
-- No high priority signals present
-- Thought clearly trails off
-- Multiple incomplete indicators
-- User appears mid-formulation
-
-3. When uncertain:
-- If you can understand the intent → YES
-- If meaning is unclear → NO
-- Always make a binary decision
-- Never request clarification
-
-Examples:
-# Incomplete despite corrections
-[{"role": "assistant", "content": "What would you like to know about?"}, 
- {"role": "user", "content": "Can you tell me about"}]
-Output: NO
-
-# Complete despite multiple artifacts
-[{"role": "assistant", "content": "I can help you learn."}, 
- {"role": "user", "content": "How do you I mean what's the best way to learn programming"}]
-Output: YES
-
-# Trailing off incomplete
-[{"role": "assistant", "content": "I can explain anything."}, 
- {"role": "user", "content": "I was wondering if you could tell me why"}]
-Output: NO
