## [Unreleased]
### Added
- Added new languages to AsyncAI in `AsyncAITTSService` and
`AsyncAIHttpTTSService`. New `languages`: `pt`, `nl`, `ar`, `ru`, `ro`, `ja`,
`he`, `hy`, `tr`, `hi`, `zh`.
- Updated the default AsyncAI TTS model to `asyncflow_multilingual_v1.0` for
improved accuracy and broader language coverage.
- Added new Gradium services, `GradiumSTTService` and `GradiumTTSService`, for
speech-to-text and text-to-speech functionality using Gradium's API.
### Changed
- Updated `CartesiaSTTService` to return the full transcription `result` in the
`TranscriptionFrame` and `InterimTranscriptionFrame`. This provides access to
word timestamp data.
- If an unexpected exception is caught, or if `FrameProcessor.push_error()` is
called with an exception, the file name and line number where the exception
occured are now logged.
- Improved interruption handling to prevent bots from repeating themselves.
LLM services that return multiple sentences in a single response (e.g.,
`GoogleLLMService`) are now split into individual sentences before being sent
to TTS. This ensures interruptions occur at sentence boundaries, preventing
the bot from repeating content after being interrupted during long responses.
- Text Aggregation Improvements:
- **Breaking Change**: `BaseTextAggregator.aggregate()` now returns
`AsyncIterator[Aggregation]` instead of `Optional[Aggregation]`. This
enables the aggregator to return multiple results based on the provided
text.
- Refactored text aggregators to use inheritance: `SkipTagsAggregator` and
`PatternPairAggregator` now inherit from `SimpleTextAggregator`, reusing
the base class's sentence detection logic.
- Updated `AICFilter` to use Quail STT as the default model
(`AICModelType.QUAIL_STT`). Quail STT is optimized for human-to-machine
interaction (e.g., voice agents, speech-to-text) and operates at a native
sample rate of 16 kHz with fixed enhancement parameters.
- Updated Deepgram logging to include Deepgram request IDs for improved debugging.
- Updated Smart Turn model weights to v3.1.
- Smart Turn analyzer now uses the full context of the turn rather than just the
audio since VAD last triggered.
### Deprecated
- Package `pipecat.sync` is deprecated, use `pipecat.utils.sync` instead.
- The `noise_gate_enable` parameter in `AICFilter` is deprecated and no longer
has any effect. Noise gating is now handled automatically by the AIC VAD
system. Use `AICFilter.create_vad_analyzer()` for VAD functionality instead.
- NVIDIA Services name changes (all functionality is unchanged):
- `NimLLMService` is now deprecated, use `NvidiaLLMService` instead.
- `RivaSTTService` is now deprecated, use `NvidiaSTTService` instead.
- `RivaTTSService` is now deprecated, use `NvidiaTTSService` instead.
- Use `uv pip install pipecat-ai[nvidia]` instead of
`uv pip install pipecat-ai[riva]`
### Fixed
- Fixed an issue in `ElevenLabsTTSService` where character usage metrics were
only reported on the first TTS generation per turn.
- Fixed an issue where `LLMTextFrame.skip_tts` was being overwritten by LLM
services.
- Fixed sentence aggregation to correctly handle ambiguous punctuation in
streaming text, such as currency ("$29.95") and abbreviations ("Mr. Smith").
- Fixed bug in `PatternPairAggregator` where pattern handlers could be called
multiple times for `KEEP` or `AGGREGATE` patterns.
- Fixed an issue in `SarvamTTSService` where the last sentence was not being
spoken. Now, audio is flushed when the TTS services receives the
`LLMFullResponseEndFrame` or `EndFrame`.
- Fixed an issue in `AWSTranscribeSTTService` where the `region` arg was
always set to `us-east-1` when providing an AWS_REGION env var.
- Fixed an issue in `DeepgramTTSService` where a `TTSStoppedFrame` was
incorrectly pushed after a functional call. This caused an issue with the
voice-ui-kit's conversational panel rending of the LLM output after a
function call.
