The enable_logging and enable_ssml_parsing URL params used truthy checks,
so False was treated the same as None (both skipped). Also, Python's
str(False) produces "False" but the API expects lowercase "false".
Additionally, add enable_logging support to ElevenLabsHttpTTSService
which was missing entirely.
When the STT p99 timeout fires without a transcript, the turn stop
strategy previously did nothing — falling through to the 5-second
user_turn_stop_timeout. Now, a _timeout_expired flag tracks when the
timeout has elapsed so that a late transcript triggers the turn stop
immediately instead of waiting for the fallback.
Previously settings updates were ignored with a TODO comment. Now when
model/language changes via STTUpdateSettingsFrame the service disconnects
and reconnects with the new query parameters.
Key changes:
- Implement _update_settings to disconnect/reconnect on changes
- Check `is not State.OPEN` in run_stt to catch CLOSING state
- Send `done` command before closing for clean session shutdown
- Capture websocket reference in _disconnect_websocket to prevent a
concurrent _connect from having its new connection nulled by a stale
finally block
The strategy schedules background tasks during setup. Fast-running
tests could observe state before those tasks had a chance to run;
yielding once via asyncio.sleep(0) ensures they do.
Enable callers to get a compact version of context messages suitable
for serialization, logging, and debugging tools. For standard
messages, known binary data (base64 images, audio) is fully elided.
For LLM-specific messages, long string values are recursively
truncated. Adapter get_messages_for_logging() methods now use this.
Example files can live under subdirectories (e.g. foundational/01.py),
so the recording path needs its parent directory created before the
audio file is written.
Replaces the per-frame asyncio.Event signaling with a monotonic
timestamp updated on each audio frame. The handler sleeps until the
next deadline (last_audio_time + timeout), recomputing on each wake-up
to account for audio arriving during sleep.
This avoids waking the handler on every audio frame (~50/s at 20ms
chunks), and guarantees detection latency is bounded by timeout rather
than 2 * timeout.
Also renames audio_starvation_timeout to audio_idle_timeout and
associated identifiers for consistency with existing pipecat naming
(user_idle_timeout, etc.).
These are TypedDicts (plain dicts at runtime), so no behavioral change
— just more descriptive type hints for readers. Use ToolParam instead
of FunctionToolParam for the Responses adapter to reflect that custom
non-function tools are supported. Use ChatCompletionToolParam instead
of Any for the completions adapter return type. Update tests to use
typed params in expected values.
During pipeline shutdown, proxy tasks must be cancelled before observer
resources are cleaned up. Previously, stop() was called inside
_cancel_tasks() and start() was called in _start_tasks(), which could
lead to proxy tasks still consuming frames after observer resources
were closed.
Now the lifecycle is explicit in _handle_start_frame: start() after all
observers are loaded, and stop() before cleanup() on shutdown.
Also fixes misleading variable name in TaskObserver.cleanup() where
iterating self._proxies yields observer keys, not Proxy values.
Fixes#4195
Move event.clear() from finally block to success path in
IdleFrameProcessor and UserIdleProcessor._idle_task_handler().
The finally block unconditionally cleared signals set during
async timeout callbacks, causing false-positive idle detection.
Closes#3402
