Audio filters like RNNoise, KrispViva, and AIC return empty bytes while
buffering audio to accumulate their required frame size. These empty
frames were flowing downstream, causing misleading "Empty audio frame
received for STT service" warnings.
Skip the frame in BaseInputTransport when audio is empty, preventing
unnecessary processing in VAD and downstream processors.
Fixes#3517
Before this change, settings updates were often not applied. For example, a `TTSUpdateSettingsFrame` queued while the bot was speaking would only have an effect at the end of the bot's reply, and any interruption before the end of the reply would "cancel" the update.
- Storage mode: for use in `self._settings`. All fields should be specified, i.e. should not be `NOT_GIVEN`.
- Delta mode: for use in `*UpdateSettingsFrame`.
In service of this, this commit:
- Adds a runtime check that all fields are specified in storage mode
- Updates all services to specify all fields in stored settings
- Updates all services to no longer check for `is_given` in stored settings (not necessary anymore)
- Updates relevant docstrings
- Renames `update` to `delta` in `*UpdateSettingsFrame`
- Updates community integrations guide
Commit 859cd7c9 refactored STT TTFB measurement to use the base class
start_ttfb_metrics/stop_ttfb_metrics, which are gated behind
can_generate_metrics(). Soniox and AWS Transcribe never overrode this
method (default returns False), so TTFB was silently never reported.
Split the single "changed" entry into separate "added", "changed", and "deprecated" entries for clarity. Add a note about the subtle behavior change in the deprecated set_model/set_voice/set_language methods.
Replace self-referential `pipecat-ai[local-smart-turn-v3]` extra in core
dependencies with the actual packages (`transformers`, `onnxruntime`).
Self-referential extras are not supported by Poetry and cause dependency
resolution failures. Since these are required by the default turn stop
strategy (LocalSmartTurnAnalyzerV3), they belong in core dependencies.
- Remove `local-smart-turn-v3` optional extra from pyproject.toml
- Remove try/except ModuleNotFoundError guard (now always installed)
- Remove `--extra local-smart-turn-v3` from CI workflows
Remove the deprecation warning and __post_init__ override. Also fix the
default value for remote_participants to use field(default_factory=dict)
instead of None.
Change the version specifier from `>=0.2.8` to
`~=0.2.8` for the `speechmatics-voice` package.
This ensures compatibility with future patch
versions while preventing potential breaking
changes from minor updates.
