-## [0.0.58] - 2025-02-26
+## Unreleased
 
 ### Added
 
-- Added track-specific audio event `on_track_audio_data` to
-  `AudioBufferProcessor` for accessing separate input and output audio tracks.
-
-- Pipecat version will now be logged on every application startup. This will
-  help us identify what version we are running in case of any issues.
-
-- Added a new `StopFrame` which can be used to stop a pipeline task while
-  keeping the frame processors running. The frame processors could then be used
-  in a different pipeline. The difference between a `StopFrame` and a
-  `StopTaskFrame` is that, as with `EndFrame` and `EndTaskFrame`, the
-  `StopFrame` is pushed from the task and the `StopTaskFrame` is pushed upstream
-  inside the pipeline by any processor.
-
-- Added a new `PipelineTask` parameter `observers` that replaces the previous
-  `PipelineParams.observers`.
-
-- Added a new `PipelineTask` parameter `check_dangling_tasks` to enable or
-  disable checking for frame processors' dangling tasks when the Pipeline
-  finishes running.
-
-- Added new `on_completion_timeout` event for LLM services (all OpenAI-based
-  services, Anthropic and Google). Note that this event will only get triggered
-  if LLM timeouts are setup and if the timeout was reached. It can be useful to
-  retrigger another completion and see if the timeout was just a blip.
-
-- Added new log observers `LLMLogObserver` and `TranscriptionLogObserver` that
-  can be useful for debugging your pipelines.
-
 - Added `room_url` property to `DailyTransport`.
 
 - Added `addons` argument to `DeepgramSTTService`.

 ### Changed
 
-- ⚠️ `PipelineTask` now requires keyword arguments (except for the first one for
-  the pipeline).
-
-- Updated `PlayHTHttpTTSService` to take a `voice_engine` and `protocol` input
-  in the constructor. The previous method of providing a `voice_engine` input
-  that contains the engine and protocol is deprecated by PlayHT.
-
-- The base `TTSService` class now strips leading newlines before sending text
-  to the TTS provider. This change is to solve issues where some TTS providers,
-  like Azure, would not output text due to newlines.
-
-- `GrokLLMSService` now uses `grok-2` as the default model.
-
-- `AnthropicLLMService` now uses `claude-3-7-sonnet-20250219` as the default
-  model.
-
-- `RimeHttpTTSService` needs an `aiohttp.ClientSession` to be passed to the
-  constructor as all the other HTTP-based services.
-
-- `RimeHttpTTSService` doesn't use a default voice anymore.
-
 - `DeepgramSTTService` now uses the new `nova-3` model by default. If you want
   to use the previous model you can pass `LiveOptions(model="nova-2-general")`.

-### Deprecated
-
-- `PipelineParams.observers` is now deprecated, you the new `PipelineTask`
-  parameter `observers`.
-
-### Removed
-
-- Remove `TransportParams.audio_out_is_live` since it was not being used at all.
-
 ### Fixed
 
-- Fixed a `GoogleLLMService` that was causing an exception when sending inline
-  audio in some cases.
-
-- Fixed an `AudioContextWordTTSService` issue that would cause an `EndFrame` to
-  disconnect from the TTS service before audio from all the contexts was
-  received. This affected services like Cartesia and Rime.
-
-- Fixed an issue that was not allowing to pass an `OpenAILLMContext` to create
-  `GoogleLLMService`'s context aggregators.
-
-- Fixed a `ElevenLabsTTSService`, `FishAudioTTSService`, `LMNTTTSService` and
-  `PlayHTTTSService` issue that was resulting in audio requested before an
-  interruption being played after an interruption.
-
-- Fixed `match_endofsentence` support for ellipses.
-
-- Fixed an issue that would cause undesired interruptions via
-  `EmulateUserStartedSpeakingFrame` when only interim transcriptions (i.e. no
-  final transcriptions) where received.
-
-- Fixed an issue where `EndTaskFrame` was not triggering
-  `on_client_disconnected` or closing the WebSocket in FastAPI.
-
-- Fixed an issue in `DeepgramSTTService` where the `sample_rate` passed to the
-  `LiveOptions` was not being used, causing the service to use the default
-  sample rate of pipeline.
-
-- Fixed a context aggregator issue that would not append the LLM text response
-  to the context if a function call happened in the same LLM turn.
-
-- Fixed an issue that was causing HTTP TTS services to push `TTSStoppedFrame`
-  more than once.
-
-- Fixed a `FishAudioTTSService` issue where `TTSStoppedFrame` was not being
-  pushed.

-"""Audio Recording Example with Pipecat.
-
-This example demonstrates how to record audio from a conversation between a user and an AI assistant,
-saving both merged and individual audio tracks. It showcases the AudioBufferProcessor's capabilities
-to handle both combined and separate audio streams.
-
-The example:
-    1. Sets up a basic conversation with an AI assistant
-    2. Records the entire conversation
-    3. Saves three separate WAV files:
-        - A merged recording of both participants
-        - Individual recording of user audio
-        - Individual recording of assistant audio
-
-Example usage (run from pipecat root directory):
-    $ pip install "pipecat-ai[daily,openai,cartesia,silero]"
-    $ pip install -r dev-requirements.txt
-    $ python examples/foundational/34-audio-recording.py
-
-Requirements:
-    - OpenAI API key (for GPT-4)
-    - Cartesia API key (for text-to-speech)
-    - Daily API key (for video/audio transport)
-
-    Environment variables (.env file):
-        OPENAI_API_KEY=your_openai_key
-        CARTESIA_API_KEY=your_cartesia_key
-        DAILY_API_KEY=your_daily_key
-
-The recordings will be saved in a 'recordings' directory with timestamps:
-    recordings/
-        merged_20240315_123456.wav  (Combined audio)
-        user_20240315_123456.wav    (User audio only)
-        bot_20240315_123456.wav     (Bot audio only)
-
-Note:
-    This example requires the AudioBufferProcessor with track-specific audio support,
-    which provides both 'on_audio_data' and 'on_track_audio_data' events for
-    handling merged and separate audio tracks respectively.

-### New! Using Gemini 2.0 Flash Lite with Daily
+### New! Using Gemini with Daily
 
-We have introduced support for Google's Gemini 2.0 Flash Lite model in this example. This lightweight model offers faster response times and reduced costs while maintaining good conversational capabilities.
+We have introduced a new example file that uses Gemini. You can find the code within bot_daily_gemini.py.
+If you want to spin up a Gemini-based bot for this demo, instead of an OpenAI-based bot, call the same properties above but on the `daily_gemini_start_bot` endpoint instead.
 
-**Quick Start**
-To use the Gemini-based bot instead of OpenAI:
+For example:
 
 ```shell
 curl -X POST "http://localhost:7860/daily_gemini_start_bot" \                                                                                                        py pipecat
@@ -119,27 +119,7 @@ curl -X POST "http://localhost:7860/daily_gemini_start_bot" \
      -d '{"detectVoicemail": true}'
 ```
 
-All request body parameters supported by /daily_start_bot (such as detectVoicemail, dialoutNumber, etc.) are also compatible with /daily_gemini_start_bot.
-
-This example uses context switching to help steer the bot in the right direction. As Flash Lite is a smaller model, breaking the prompt down into smaller piece helps to improve the bot's accuracy.
-
-For example, instead of giving one large prompt like:
-
-```python
-system_instruction="""You are a chatbot that needs to detect if you're talking to a voicemail system or human, then either leave a message or have a conversation. If it's voicemail, say "Hello, this is a message..." and hang up. If it's a human, introduce yourself and be helpful until they say goodbye."""
-```
-
-We break it into stages:
-
-First prompt focuses only on detection: "Determine if this is voicemail or human"
-After detection, we switch to a new context: either "Leave this specific voicemail message" or "Have a conversation with the human".
-
-**Implementation Details**
-The implementation is available in bot_daily_gemini.py and features:
-
-- Staged prompting approach: Breaking down complex tasks into smaller, more focused prompts to improve the lightweight model's performance
-- Dynamic context switching: The bot can change its behavior in real-time based on what it detects (voicemail vs. human caller)
-- Function-based architecture: Uses function calling to trigger context switches and call termination
+Any request body properties supported by `/daily_start_bot` (such as "detectVoicemail", "dialoutnumber", etc) can also be passed to `/daily_gemini_start_bot`. The only difference is that calling the Gemini endpoint will start a Gemini bot session.

+**Operating Procedure:**
 
-Then call the function switch_to_voicemail_response.
+**Phase 1: Initial Call Answer - Listen for Voicemail Greeting**
 
-If it sounds like a human (saying hello, asking questions, etc.), call the function switch_to_human_conversation.
+**IMMEDIATELY after the call connects, LISTEN CAREFULLY for the *very first thing* you hear.**
 
-DO NOT say anything until you've determined if this is a voicemail or human."""
+**Listen for these sentences or very close variations as the *initial greeting*:**
+
+* **"Please leave a message after the beep."**
+* **"No one is available to take your call."**
+* **"Record your message after the tone."**
+* **"You have reached voicemail for..."** (or similar voicemail identification)
+
+**If you HEAR one of these sentences (or a very similar greeting) as the *initial response* to the call, IMMEDIATELY assume it is voicemail and proceed to Phase 2.**
+
+**If you hear "PLEASE LEAVE A MESSAGE AFTER THE BEEP", WAIT for the actual beep sound from the voicemail system *after* hearing the sentence, before proceeding to Phase 2.**
+
+**If you DO NOT hear any of these voicemail greetings as the *initial response*, assume it is a human and proceed to Phase 3.**
+
+
+**Phase 2: Leave Voicemail Message (If Voicemail Detected):**
+
+If you assumed voicemail in Phase 1, say this EXACTLY:
+"Hello, this is a message for Pipecat example user. This is Chatbot. Please call back on 123-456-7891. Thank you."
+
+**Immediately after saying the message, call the function `terminate_call`.**
+**DO NOT SAY ANYTHING ELSE. SILENCE IS REQUIRED AFTER `terminate_call`.**
+
+
+**Phase 3: Human Interaction (If No Voicemail Greeting Detected in Phase 1):**
+
+If you did not detect a voicemail greeting in Phase 1 and a human answers, say:
+"Oh, hello! I'm a friendly chatbot. Is there anything I can help you with?"
+
+Keep your responses **short and helpful.**
+
+If the human is finished, say:
+"Okay, thank you! Have a great day!"
+
+**Then, immediately call the function `terminate_call`.**
+
+
+**VERY IMPORTANT RULES - DO NOT DO THESE THINGS:**
+
+* **DO NOT SAY "Please leave a message after the beep."**
+* **DO NOT SAY "No one is available to take your call."**
+* **DO NOT SAY "Record your message after the tone."**
+* **DO NOT SAY ANY voicemail greeting yourself.**
+* **Only check for voicemail greetings in Phase 1, *immediately after the call connects*.**
+* **After voicemail or human interaction, ALWAYS call `terminate_call` immediately.**
+* **Do not speak after calling `terminate_call`.**
+* Your speech will be audio, so use simple language without special characters.
