5b696bd4ae Fix self-referential dependency that breaks Poetry 2.x
Replace `pipecat-ai[local-smart-turn-v3]` in main dependencies with
the actual packages (transformers, onnxruntime) to eliminate the
circular dependency that causes Poetry to error with:
"Package 'pipecat-ai[local-smart-turn-v3]' is listed as a dependency of itself."

6. Use ⚠️ emoji prefix for breaking changes.
7. **Write changes in user-facing terms first.** Lead with what users of the framework will notice: new APIs, changed behavior, new parameters, fixed bugs they might have hit, etc. Implementation details (internal refactoring, how something is wired up under the hood) can be included as secondary context after the user-facing description, but should never be the *only* content of a changelog entry when there is a user-visible effect.
**Good** (user-facing first, implementation detail as context):
```
- Turn completion instructions now persist correctly across full context updates when using `system_instruction`. Previously they were injected as a context system message, which caused warning spam and didn't survive context updates.
```
**Bad** (implementation detail only, no user-facing framing):
```
- Fixed turn completion instructions being injected as a context system message instead of using `system_instruction`.

Document a Python module and its classes using Google-style docstrings following project conventions. The class name is provided as an argument.
## Instructions
1. Determine what to document based on the argument:
1. First, find the class in the codebase:
```
Search for "class ClassName" in src/pipecat/
```
**If a module path is provided** (e.g. `src/pipecat/audio/vad/vad_analyzer.py`):

#### 8b: Add to docs.json
Add the new page path to `DOCS_PATH/docs.json` in the correct navigation group. The path format is `server/services/{category}/{provider}` (without the `.mdx` extension).
Find the matching group in the navigation structure:
- **STT** → `"group": "Speech-to-Text"` under Services
- **TTS** → `"group": "Text-to-Speech"` under Services
- **LLM** → `"group": "LLM"` under Services

- **Video** → `"group": "Video"` under Services
- **Memory** → `"group": "Memory"` under Services
- **Vision** → `"group": "Vision"` under Services
- **Analytics** → `"group": "Analytics & Monitoring"` under Services
Insert the new entry **alphabetically** within the group's `pages` array. For example, adding a new STT service "foo":
```json
{
"group": "Speech-to-Text",
"pages": [
"server/services/stt/assemblyai",
"server/services/stt/aws",

#### 8c: Add to supported-services.mdx
Add a new row to the correct category table in `DOCS_PATH/server/services/supported-services.mdx`.
Use this format:
```
| [DisplayName](/server/services/{category}/{provider}) | `pip install "pipecat-ai[package]"` |
```
To determine the correct values:
- **DisplayName**: Use the service's human-readable name (e.g., "ElevenLabs", "AWS Polly", "Google Gemini")
- **package**: Look at the service's `pyproject.toml` extras or the import pattern in the source code. For example, if the service is in `src/pipecat/services/foo/`, the package is typically `foo`.
- If no pip dependencies are required, use `No dependencies required` instead.
Insert the new row **alphabetically** within the table. Match the column alignment of the existing rows.

prompt: |
You are updating documentation for the pipecat-ai/docs repository based on
changes merged in PR #${{ steps.pr.outputs.number }} of pipecat-ai/pipecat.
## Setup
1. Read the skill instructions at `.claude/skills/update-docs/SKILL.md`
2. Read the source-to-doc mapping at `.claude/skills/update-docs/SOURCE_DOC_MAPPING.md`
3. The docs repository is checked out at `./_docs/`
## Get the diff
Run `gh pr diff ${{ steps.pr.outputs.number }}` to see what changed in the PR.
Also run `gh pr diff ${{ steps.pr.outputs.number }} --name-only` to get the list of changed files.
Filter to source files matching the directories listed in SKILL.md Step 3.
If no relevant source files were changed, exit with "No documentation changes needed."
## Follow the skill instructions
Apply the SKILL.md workflow (Steps 3-9) with these adaptations for automation:
### Docs path
Use `./_docs/` — it's already checked out. Do not ask for a path.
### Branch management
- Branch name: `docs/pr-${{ steps.pr.outputs.number }}`
- Work inside `./_docs/` for all doc edits and git operations
- Check if the branch already exists on the remote:
```bash
cd _docs && git fetch origin docs/pr-${{ steps.pr.outputs.number }} 2>/dev/null
```
- If it exists: check it out (supports workflow re-runs)
- If not: create it from main
### Git config
Before committing in `_docs`, set:
```bash
git config user.name "github-actions[bot]"
git config user.email "github-actions[bot]@users.noreply.github.com"
```
### No interactive questions
Do not ask questions. If you encounter gaps (unmapped files, missing sections,
ambiguous changes), note them in the PR body under "## Gaps identified".
### Creating the docs PR
After committing all changes in `_docs`, push and create a PR:
```bash
cd _docs
git push -u origin docs/pr-${{ steps.pr.outputs.number }}
GH_TOKEN=$DOCS_SYNC_TOKEN gh pr create \
--repo pipecat-ai/docs \
--label auto-docs \
--title "docs: update for pipecat PR #${{ steps.pr.outputs.number }}" \
--body "$(cat <<'BODY'
Automated documentation update for [pipecat PR #${{ steps.pr.outputs.number }}](https://github.com/pipecat-ai/pipecat/pull/${{ steps.pr.outputs.number }}).
## Changes
<summarize each doc page updated and what changed>
## Gaps identified
<any unmapped files, missing doc pages, or missing sections — or "None">
BODY
)"
```
### Re-run handling
If `gh pr create` fails because a PR from that branch already exists,
push the updated commits and use `gh pr edit` to update the body instead.
### No-op
If after analyzing the diff you determine no documentation changes are needed
(e.g., only skip-listed files changed, or changes don't affect public API docs),
exit cleanly without creating a branch or PR. Output "No documentation changes needed."
## Important rules
- Only modify files inside `./_docs/` — never modify pipecat source code
- Follow the conservative editing rules from SKILL.md Step 6
- Read each doc page fully before editing (SKILL.md Guidelines)
- Use `GH_TOKEN=$DOCS_SYNC_TOKEN` for all `gh` commands targeting pipecat-ai/docs

- `@dataclass`: Frame types, context aggregator pairs, internal data containers

@@ -121,59 +109,56 @@ Once your PR is submitted, post in the `#community-integrations` Discord channel
#### Key requirements:
- **`_process_context(self, context: LLMContext)`** — The main method that processes an LLM context and generates a response. Each LLM service overrides `process_frame` to extract context from `LLMContextFrame` and calls `_process_context`.
- **`adapter_class`** — Class attribute pointing to a `BaseLLMAdapter` subclass. Defaults to `OpenAILLMAdapter`. Non-OpenAI services must implement their own adapter (see `src/pipecat/adapters/base_llm_adapter.py`) with methods:
- `get_llm_invocation_params(context)` — Extract provider-specific params from universal context
- `to_provider_tools_format(tools_schema)` — Convert standard tools to provider format
- `get_messages_for_logging(context)` — Format messages for logging
- Reference adapters: `src/pipecat/adapters/services/` (anthropic, gemini, bedrock, etc.)
- **Frame sequence:** Output must follow this frame sequence pattern:
- `LLMFullResponseStartFrame` — Signals the start of an LLM response
- `LLMTextFrame` — Contains LLM content, typically streamed as tokens
- `LLMFullResponseEndFrame` — Signals the end of an LLM response
- **Thought frames (reasoning models):** If the model supports extended thinking / chain-of-thought, emit thought frames alongside the response:
- `LLMThoughtStartFrame` — Signals the start of a thought
- `LLMThoughtTextFrame` — Contains thought content, streamed as tokens
- `LLMThoughtEndFrame` — Signals the end of a thought
- `LLMFullResponseStartFrame` - Signals the start of an LLM response
- `LLMTextFrame` - Contains LLM content, typically streamed as tokens
- `LLMFullResponseEndFrame` - Signals the end of an LLM response
- **Context aggregation** is handled by the framework via `LLMContext` + `LLMContextAggregatorPair`. The LLM service just processes context it receives — no need to implement aggregators.
- **Context aggregation:** Implement context aggregation to collect user and assistant content:
- Aggregators come in pairs with a `user()` instance and `assistant()` instance
- Context must adhere to the `LLMContext` universal format
- Aggregators should handle adding messages, function calls, and images to the context
### TTS (Text-to-Speech) Services

## Implementation Guidelines
### Naming Conventions
#### Package and Repository Naming
Use the `pipecat-{vendor}` naming convention for your PyPI package and repository:
- `pipecat-{vendor}` — for single-service integrations (e.g., `pipecat-deepdub`)
- `pipecat-{vendor}-{type}` — when a vendor offers multiple service types (e.g., `pipecat-upliftai-stt`, `pipecat-upliftai-tts`)
This convention makes community packages easily discoverable via PyPI search and clearly identifies them as part of the Pipecat ecosystem.
#### Class Naming
- **STT:** `VendorSTTService`
- **LLM:** `VendorLLMService`

### Service Settings
### Dynamic Settings Updates
Every AI service (STT, LLM, TTS, image generation, etc.) exposes a **Settings dataclass** that serves two roles:
1. **Store mode** — the service's `self._settings` holds the current value of every runtime-updatable field.
2. **Delta mode** — an update frame (e.g. `TTSUpdateSettingsFrame`) specifies only the fields that should change; unspecified fields remain `NOT_GIVEN`.
#### Defining your Settings class
Extend `STTSettings`, `TTSSettings`, `LLMSettings`, or `ImageGenSettings` (or, if your service directly subclasses `AIService`, `ServiceSettings`). The base classes already provide common fields (e.g. `model`, `voice`, `language`). You only need to add **service-specific knobs that should be runtime-updatable**:
STT, LLM, and TTS services support `ServiceUpdateSettingsFrame` for dynamic configuration changes. The base STTService has an `_update_settings()` method that handles settings, and the private `_settings` `Dict` is used to store settings and provide access to the subclass.
```python
from dataclasses import dataclass, field
async def set_language(self, language: Language):
"""Set the recognition language and reconnect.
from pipecat.services.settings import TTSSettings, NOT_GIVEN
@dataclass
class MyTTSSettings(TTSSettings):
"""Settings for MyTTS service.
Parameters:
speaking_rate: Speed multiplier (0.52.0).
Args:
language: The language to use for speech recognition.
"""
speaking_rate: float | None = field(default_factory=lambda: NOT_GIVEN)
```
**What goes in Settings vs. `__init__` params:**
| Belongs in Settings | Stays as `__init__` params |
| -------------------------------------------------------- | ----------------------------------------- |
| Model name, voice, language | API keys, auth tokens |
| Service-specific tuning knobs (rate, pitch, temperature) | Base URLs, endpoint overrides |
| Anything users may want to change mid-session | Audio encoding, sample format |
| | Connection parameters (timeouts, retries) |
The rule of thumb: if a caller might send an update frame to change it at runtime, it belongs in Settings. Everything else is init-only config stored as `self._xxx`.
#### Wiring settings into `__init__`
Accept an **optional** `settings` parameter. Build a `default_settings` object with all fields set to real values, then merge any caller overrides with `apply_update`.
Add a `Settings` **class attribute** that points to your settings dataclass. This lets callers access the settings class through the service itself (e.g. `MyTTSService.Settings(...)`) without a separate import:
```python
from typing import Optional
class MyTTSService(TTSService):
Settings = MyTTSSettings
_settings: Settings
def __init__(
self,
*,
api_key: str,
settings: Optional[Settings] = None,
**kwargs,
):
# 1. Defaults — every field has a real value (store mode).
default_settings = self.Settings(
model="my-model-v1",
voice="default-voice",
language="en",
speaking_rate=1.0,
)
# 2. Merge caller overrides (only given fields win).
if settings is not None:
default_settings.apply_update(settings)
# 3. Pass the fully-populated settings to the base class.
super().__init__(settings=default_settings, **kwargs)
# 4. Init-only config stored separately.
self._api_key = api_key
```
This pattern lets callers override only what they care about:
```python
# Uses all defaults
svc = MyTTSService(api_key="sk-xxx")
# Overrides just the voice — access Settings through the service class
svc = MyTTSService(
api_key="sk-xxx",
settings=MyTTSService.Settings(voice="custom-voice"),
)
```
#### Reacting to runtime changes
AI services support runtime configuration changes via `*UpdateSettingsFrame`s (e.g. `STTUpdateSettingsFrame`, `TTSUpdateSettingsFrame`, `LLMUpdateSettingsFrame`).
To react to runtime setting changes, override `_update_settings`. The base implementation applies the delta to `self._settings` and returns a `dict` mapping each changed field name to its **pre-update** value. Your override should call `super()` first, then act on the changed fields. A common implementation might look like:
```python
async def _update_settings(self, update: TTSSettings) -> dict[str, Any]:
"""Apply a settings update, reconfiguring the connection if needed."""
changed = await super()._update_settings(update)
if not changed:
return changed
logger.info(f"Switching STT language to: [{language}]")
self._settings["language"] = language
await self._disconnect()
await self._connect()
return changed
```
The dict keys work like a set for membership tests (`"language" in changed`) and truthiness (`if changed`). Use `changed.keys() - {"language"}` for set difference, or `changed["language"]` to inspect the previous value of a field.
Note that, in this example, the service requires a reconnect to apply the new language. Consider, for each setting, whether your service requires reconnection or can apply changes in-place.
If your service can't yet apply certain settings at runtime, call `self._warn_unhandled_updated_settings(changed)` with any unhandled field names so users get a clear log message:
```python
async def _update_settings(self, update: TTSSettings) -> dict[str, Any]:
changed = await super()._update_settings(update)
if not changed:
return changed
if "language" in changed:
await self._update_language()
else:
# TODO: this should be temporary - handle changes to other settings soon!
self._warn_unhandled_updated_settings(changed.keys() - {"language"})
return changed
```
Note that, in this example, Deepgram requires the websocket connection be disconnected and reconnected to reinitialize the service with the new value. Consider if your service requires reconnection.

# Pipecat Examples
This directory contains examples showing how to build voice and multimodal agents with Pipecat.
This directory contains examples to help you learn how to build with Pipecat.
## Setup
## Getting Started
1. Follow the [README](https://github.com/pipecat-ai/pipecat/blob/main/README.md#%EF%B8%8F-contributing-to-the-framework) steps to get your local environment configured.
New to Pipecat? Start here:
> **Run from root directory**: Make sure you are running the steps from the root directory.
- **[Quickstart](quickstart/)** - Get your first voice AI bot running in 5 minutes _(coming soon)_
- **[Client/Server Web](client-server-web/)** - Learn to build web applications with Pipecat's client SDKs _(coming soon)_
- **[Phone Bot with Twilio](phone-bot-twilio/)** - Connect your bot to a phone number _(coming soon)_
> **Using local audio?**: The `LocalAudioTransport` requires a system dependency for `portaudio`. Install the dependency to use the transport.
## Foundational Examples
2. Copy the [`env.example`](../env.example) file and add API keys for services you plan to use:
Single-file examples that introduce core Pipecat concepts one at a time. These examples:
```bash
cp env.example .env
# Edit .env with your API keys
```
- Build on each other progressively
- Focus on specific features or integrations
- Are used for testing with every Pipecat release
3. Run any example:
See the **[Foundational Examples README](foundational/)** for the complete list.
```bash
uv run python getting-started/01-say-one-thing.py
```
## More Advanced Examples
4. Open the web interface at http://localhost:7860/client/ and click "Connect"
Ready to explore complex use cases? Visit **[pipecat-examples](https://github.com/pipecat-ai/pipecat-examples)** for:
## Running examples with other transports
Most examples support running with other transports, like Twilio or Daily.
### Daily
You need to create a Daily account at https://dashboard.daily.co/u/signup. Once signed up, you can create your own room from the dashboard and set the environment variables `DAILY_ROOM_URL` and `DAILY_API_KEY`. Alternatively, you can let the example create a room for you (still needs `DAILY_API_KEY` environment variable). Then, start any example with `-t daily`:
```bash
uv run getting-started/06-voice-agent.py -t daily
```
### Twilio
It is also possible to run the example through a Twilio phone number. You will need to setup a few things:
1. Install and run [ngrok](https://ngrok.com/download).
```bash
ngrok http 7860
```
2. Configure your Twilio phone number. One way is to setup a TwiML app and set the request URL to the ngrok URL from step (1). Then, set your phone number to use the new TwiML app.
Then, run the example with:
```bash
uv run getting-started/06-voice-agent.py -t twilio -x NGROK_HOST_NAME
```
## Directory Structure
### [`getting-started/`](./getting-started/)
Progressive introduction to Pipecat, from minimal TTS to a full voice agent with function calling.
### [`voice/`](./voice/)
Full STT + LLM + TTS voice agent pipelines showcasing different speech service providers (Deepgram, ElevenLabs, Cartesia, etc.)
### [`function-calling/`](./function-calling/)
Function calling with different LLM providers (OpenAI, Anthropic, Google, etc.)
### [`transcription/`](./transcription/)
Speech-to-text examples with various STT providers.
### [`vision/`](./vision/)
Image description and vision capabilities with different multimodal LLMs.
### [`realtime/`](./realtime/)
Realtime and multimodal live APIs (OpenAI Realtime, Gemini Live, AWS Nova Sonic, Ultravox, Grok).
### [`persistent-context/`](./persistent-context/)
Maintaining conversation context across sessions with different providers.
### [`context-summarization/`](./context-summarization/)
Summarizing conversation context to manage token limits.
### [`update-settings/`](./update-settings/)
Changing service settings at runtime, organized by service type:
- **[`stt/`](./update-settings/stt/)** — Speech-to-text settings
- **[`tts/`](./update-settings/tts/)** — Text-to-speech settings
- **[`llm/`](./update-settings/llm/)** — LLM settings
### [`turn-management/`](./turn-management/)
Turn detection, interruption handling, and user input management.
### [`thinking-and-mcp/`](./thinking-and-mcp/)
LLM thinking/reasoning modes and MCP (Model Context Protocol) tool server integration.
### [`transports/`](./transports/)
Transport layer examples (WebRTC, Daily, LiveKit).
### [`video-avatar/`](./video-avatar/)
Video avatar integrations (Tavus, HeyGen, Simli, LemonSlice).
### [`video-processing/`](./video-processing/)
Video processing, mirroring, GStreamer, and custom video tracks.
### [`audio/`](./audio/)
Audio recording, background sounds, and sound effects.
### [`observability/`](./observability/)
Pipeline monitoring: observers, heartbeats, and Sentry metrics.
### [`rag/`](./rag/)
Retrieval-augmented generation, grounding, and long-term memory (Mem0, Gemini).
### [`features/`](./features/)
Miscellaneous features: wake phrases, live translation, service switching, voice switching, and more.
## Advanced Usage
### Customizing Network Settings
```bash
uv run python <example-name> --host 0.0.0.0 --port 8080
```
### Troubleshooting
- **No audio/video**: Check browser permissions for microphone and camera
- **Connection errors**: Verify API keys in `.env` file
- **Port conflicts**: Use `--port` to change the port

"""Example demonstrating manual context summarization via a function call.
This example shows how to trigger context summarization on demand rather than
automatically. The user can ask the bot to "summarize the conversation" and the
bot will call a function that pushes an LLMSummarizeContextFrame into the
pipeline, causing the LLM service to compress the conversation history.
Unlike example 54, automatic summarization is NOT enabled here. Summarization
only happens when the user explicitly requests it through the function call.
