## [Unreleased]
### Changed
- Updated `daily-python` to 0.21.0.
- `SimliVideoService` now accepts `api_key` and `face_id` parameters directly,
with optional `params` for `max_session_length` and `max_idle_time`
configuration, aligning with other Pipecat service patterns.
- Updated the default model to `sonic-3` for `CartesiaTTSService` and
`CartesiaHttpTTSService`.
- `FunctionFilter` now has a `filter_system_frames` arg, which controls whether
or not SystemFrames are filtered.
- Upgraded `aws_sdk_bedrock_runtime` to v0.1.1 to resolve potential CPU issues
when running `AWSNovaSonicLLMService`.
### Deprecated
- `SimliVideoService` `simli_config` parameter is deprecated. Use `api_key` and
`face_id` parameters instead.
### Removed
- Removed the `aiohttp_session` arg from `SarvamTTSService` as it's no longer
used.
### Fixed
- Fixed an issue where `DailyTransport` would timeout prematurely on join and on
leave.
- Fixed an issue in the runner where starting a DailyTransport room via
`/start` didn't support using the `DAILY_SAMPLE_ROOM_URL` env var.
- Fixed an issue in `ServiceSwitcher` where the `STTService`s would result in
all STT services producing `TranscriptionFrame`s.
- Fixed an issue in `HumeTTSService` that was only using Octave 2, which does not support the `description` field. Now, if a description is provided, it switches to Octave 1.
## [0.0.91] - 2025-10-21
### Added
- It is now possible to start a bot from the `/start` endpoint when using the
runner Daily's transport. This follows the Pipecat Cloud format with
`createDailyRoom` and `body` fields in the POST request body.
- Added an ellipsis character (`…`) to the end of sentence detection in the
string utils.
- Expanded support for universal `LLMContext` to `AWSNovaSonicLLMService`.
As a reminder, the context-setup pattern when using `LLMContext` is:
```python
context = LLMContext(messages, tools)
context_aggregator = LLMContextAggregatorPair(context)
```
(Note that even though `AWSNovaSonicLLMService` now supports the universal
`LLMContext`, it is not meant to be swapped out for another LLM service at
runtime.)
Worth noting: whether or not you use the new context-setup pattern with
`AWSNovaSonicLLMService`, some types have changed under the hood:
```python
## BEFORE:
# Context aggregator type
context_aggregator: AWSNovaSonicContextAggregatorPair
# Context frame type
frame: OpenAILLMContextFrame
# Context type
context: AWSNovaSonicLLMContext
# or
context: OpenAILLMContext
## AFTER:
# Context aggregator type
context_aggregator: LLMContextAggregatorPair
# Context frame type
frame: LLMContextFrame
# Context type
context: LLMContext
```
- Added support for `bulbul:v3` model in `SarvamTTSService` and
`SarvamHttpTTSService`.
- Added `keyterms_prompt` parameter to `AssemblyAIConnectionParams`.
- Added `speech_model` parameter to `AssemblyAIConnectionParams` to access the
multilingual model.
- Added support for trickle ICE to the `SmallWebRTCTransport`.
- Added support for updating `OpenAITTSService` settings (`instructions` and
`speed`) at runtime via `TTSUpdateSettingsFrame`.
- Added `--whatsapp` flag to runner to better surface WhatsApp transport logs.
- Added `on_connected` and `on_disconnected` events to TTS and STT
websocket-based services.
- Added an `aggregate_sentences` arg in `ElevenLabsHttpTTSService`, where the
default value is True.
- Added a `room_properties` arg to the Daily runner's `configure()` method,
allowing `DailyRoomProperties` to be provided.
- The runner `--folder` argument now supports downloading files from
subdirectories.
### Changed
- `RunnerArguments` now include the `body` field, so there's no need to add it
to subclasses. Also, all `RunnerArguments` fields are now keyword-only.
- `CartesiaSTTService` now inherits from `WebsocketSTTService`.
- Package upgrades:
- `daily-python` upgraded to 0.20.0.
- `openai` upgraded to support up to 2.x.x.
- `openpipe` upgraded to support up to 5.x.x.
- `SpeechmaticsSTTService` updated dependencies for `speechmatics-rt>=0.5.0`.
### Deprecated
- The `send_transcription_frames` argument to `AWSNovaSonicLLMService` is
deprecated. Transcription frames are now always sent. They go upstream, to be
handled by the user context aggregator. See "Added" section for details.
- Types in `pipecat.services.aws.nova_sonic.context` have been deprecated due
to changes to support `LLMContext`. See "Changed" section for details.
### Fixed
- Fixed an issue where the `RTVIProcessor` was sending duplicate
`UserStartedSpeakingFrame` and `UserStoppedSpeakingFrame` messages.
- Fixed an issue in `AWSBedrockLLMService` where both `temperature` and `top_p`
were always sent together, causing conflicts with models like Claude Sonnet 4.5
that don't allow both parameters simultaneously. The service now only includes
inference parameters that are explicitly set, and `InputParams` defaults have
been changed to `None` to rely on AWS Bedrock's built-in model defaults.
- Fixed an issue in `RivaSegmentedSTTService` where a runtime error occurred due
to a mismatch in the `_handle_transcription` method's signature.
- Fixed multiple pipeline task cancellation issues. `asyncio.CancelledError` is
now handled properly in `PipelineTask` making it possible to cancel an asyncio
task that it's executing a `PipelineRunner` cleanly. Also,
`PipelineTask.cancel()` does not block anymore waiting for the `CancelFrame`
to reach the end of the pipeline (going back to the behavior in < 0.0.83).
- Fixed an issue in `ElevenLabsTTSService` and `ElevenLabsHttpTTSService` where
the Flash models would split words, resulting in a space being inserted
between words.
- Fixed an issue where audio filters' `stop()` would not be called when using
`CancelFrame`.
- Fixed an issue in `ElevenLabsHttpTTSService`, where
`apply_text_normalization` was incorrectly set as a query parameter. It's now
being added as a request parameter.
- Fixed an issue where `RimeHttpTTSService` and `PiperTTSService` could generate
incorrectly 16-bit aligned audio frames, potentially leading to internal
errors or static audio.
- Fixed an issue in `SpeechmaticsSTTService` where `AdditionalVocabEntry` items
needed to have `sounds_like` for the session to start.
### Other
- Added foundational example `47-sentry-metrics.py`, demonstrating how to use the
`SentryMetrics` processor.
- Added foundational example `14x-function-calling-openpipe.py`.
## [0.0.90] - 2025-10-10
### Added
- Added audio filter `KrispVivaFilter` using the Krisp VIVA SDK.
- Added `--folder` argument to the runner, allowing files saved in that folder
to be downloaded from `http://HOST:PORT/file/FILE`.
- Added `GeminiLiveVertexLLMService`, for accessing Gemini Live via Google
Vertex AI.
- Added some new configuration options to `GeminiLiveLLMService`:
- `thinking`
- `enable_affective_dialog`
- `proactivity`
Note that these new configuration options require using a newer model than
the default, like "gemini-2.5-flash-native-audio-preview-09-2025". The last
two require specifying `http_options=HttpOptions(api_version="v1alpha")`.
- Added `on_pipeline_error` event to `PipelineTask`. This event will get fired
when an `ErrorFrame` is pushed (use `FrameProcessor.push_error()`).
```python
@task.event_handler("on_pipeline_error")
async def on_pipeline_error(task: PipelineTask, frame: ErrorFrame):
...
```
- Added a `service_tier` `InputParam` to the `BaseOpenAILLMService`. This
parameter can influence the latency of the response. For example `"priority"`
will result in faster completions, but in exchange for a higher price.
### Changed
- Updated `GeminiLiveLLMService` to use the `google-genai` library rather than
use WebSockets directly.
### Deprecated
- `LivekitFrameSerializer` is now deprecated. Use `LiveKitTransport` instead.
- `pipecat.service.openai_realtime` is now deprecated, use
`pipecat.services.openai.realtime` instead or
`pipecat.services.azure.realtime` for Azure Realtime.
- `pipecat.service.aws_nova_sonic` is now deprecated, use
`pipecat.services.aws.nova_sonic` instead.
- `GeminiMultimodalLiveLLMService` is now deprecated, use
`GeminiLiveLLMService`.
### Fixed
- Fixed a `GoogleVertexLLMService` issue that would generate an error if no
token information was returned.
- `GeminiLiveLLMService` will now end gracefully (i.e. after the bot has
finished) upon receiving an `EndFrame`.
- `GeminiLiveLLMService` will try to seamlessly reconnect when it loses its
connection.
## [0.0.89] - 2025-10-07
### Fixed
- Reverted a change introduced in 0.0.88 that was causing pipelines to be frozen
when using interruption strategies and processors that block interruption
frames (e.g. `STTMuteFilter`).
## [0.0.88] - 2025-10-07
### Added
- Added support for Nano Banana models to `GoogleLLMService`. For example, you
can now use the `gemini-2.5-flash-image` model to generate images.
- Added `HumeTTSService` for text-to-speech synthesis using Hume AI's expressive
voice models. Provides high-quality, emotionally expressive speech synthesis
with support for various voice models. Includes example in
`examples/foundational/07ad-interruptible-hume.py`. Use with:
`uv pip install pipecat-ai[hume]`.
### Changed
- Updated default `GoogleLLMService` model to `gemini-2.5-flash`.
### Deprecated
- PlayHT is shutting down their API on December 31st, 2025. As a result,
`PlayHTTTSService` and `PlayHTHttpTTSService` are deprecated and will be
removed in a future version.
### Fixed
- Fixed an issue with `AWSNovaSonicLLMService` where the client wouldn't
connect due to a breaking change in the AWS dependency chain.
- `PermissionError` is now caught if NLTK's `punkt_tab` can't be downloaded.
- Added `HumeTTSService` for text-to-speech synthesis using Hume AI's
expressive voice models. Provides high-quality, emotionally expressive speech
synthesis with support for various voice models. Includes example in
`examples/foundational/07ad-interruptible-hume.py`.
- Added `hume` optional dependency group for Hume AI TTS integration.
### Fixed
- Fixed an issue that would cause wrong user/assistant context ordering when
using interruption strategies.
- Fixed RTVI incoming message handling, broken in 0.0.87.
