DailyCallbacks gained a required on_dtmf_event field in PR #4047.
PR #4079 fixed this for TavusTransportClient but
LemonSliceTransportClient.setup() was not updated, causing a pydantic
ValidationError at pipeline setup time.
Only trigger handle_error for ErrorFrames originating from the active
service, not any managed service. This prevents edge cases where errors
from a non-active service could incorrectly trigger failover.
Expose a public method for retrieving all stored memories outside the
pipeline, avoiding the need for callers to reimplement client branching,
OR filter construction, and asyncio.to_thread wrapping. Simplify the
example get_initial_greeting() to use it.
Move blocking Mem0 API calls off the event loop using asyncio.to_thread().
Store messages as a fire-and-forget background task via create_task() since
the result is not needed. Insert memory messages at the configured position
in the context instead of always appending.
Closes#1741
Deepgram SDK 6.x surfaces connection errors from send_media() instead
of silently swallowing them. This causes error floods when the WebSocket
disconnects since every queued audio frame hits the dead connection.
Wrap send_media() in try/except: on failure, log one warning and set
self._connection = None so subsequent frames skip until the existing
_connection_handler reconnects.
When an InterruptionFrame arrives, the Python-side audio task is
cancelled but frames already submitted to rtc.AudioSource continue
playing from its internal buffer. This causes the bot to keep speaking
for several seconds after being interrupted.
Fix by overriding process_frame in LiveKitOutputTransport to call
audio_source.clear_queue() on InterruptionFrame, immediately flushing
the buffered audio.
ErrorFrames propagating upstream from downstream processors (e.g. TTS) would
enter the ServiceSwitcher via process_frame, traverse the active service sub-pipeline,
and reach push_frame where they incorrectly triggered failover. Now only errors whose
processor is one of the managed services trigger handle_error. Also fix the log in
handle_error to attribute errors to the actual source processor rather than the
current active_service.
Closes#4139
When Gemini Live was configured with local VAD (server-side VAD disabled),
the service was listening for the wrong frame types and not sending
ActivityStart/ActivityEnd events to the server. Now it listens for
VADUserStartedSpeakingFrame/VADUserStoppedSpeakingFrame and sends the
appropriate activity signals when local VAD is in use.
Also removes the unnecessary local SileroVADAnalyzer from server-side VAD
examples and adds a new 26a example demonstrating local VAD configuration.
Set GRPC_VERBOSITY=ERROR by default so users do not see noisy fork
handler and abseil warnings from the gRPC C library. Users can still
override by setting GRPC_VERBOSITY themselves.
nvidia-riva-client 2.25.1 ships with gencode compiled against protobuf
6.31.1, which requires a runtime >= 6.31.1. Update protobuf from 5.29.6
to >=6.31.1,<7 and grpcio-tools from 1.67.1 to 1.78.0 to match.
Regenerate frames_pb2.py with the new compiler.
Both GrokLLMService and XAIHttpTTSService use the same xAI API (api.x.ai),
so move Grok source files into the xai module. Leave deprecation shims in
the old grok/ paths for backward compatibility.
- Rename XAITTSService → XAIHttpTTSService and XAITTSSettings → XAIHttpTTSSettings
- Add language_to_xai_language() with explicit LANGUAGE_MAP using resolve_language()
- Remove deprecated InputParams, params, voice, language init params
- Remove XAI_DEFAULT_SAMPLE_RATE and XAI_PCM_CODEC constants; add encoding param
- Set sample_rate=None default (picked up from PipelineParams or user)
- Use Language.EN enum instead of string "en" for default language
- Add changelog/4031.added.md
- Add 07e-interruptible-xai.py foundational example
- Update 14g-function-calling-grok.py to use XAIHttpTTSService
- Register 07e in run-release-evals.py
Test that OpenAI Realtime, Grok Realtime, and Nova Sonic adapters
prefer init-provided system_instruction over context-provided, warn
on conflicts, and don't warn for developer messages.
Add system_instruction parameter to the Grok Realtime adapter's
get_llm_invocation_params() and call _resolve_system_instruction() to
prefer init-provided over context-provided system instructions and
warn on conflicts. Previously context-provided took precedence.
Update the Grok Realtime example to use settings.system_instruction
instead of session_properties.instructions.
