…ations SDK Rewrite the voice tracing guides for the packaged LangSmith integrations, so the snippets reflect what a customer installs and imports rather than a copied span-processor file. - Pipecat: langsmith[pipecat] + configure_pipecat(); AudioBufferProcessor + attach_audio_buffer for recording. - LiveKit: langsmith[livekit] + configure_livekit(). - OpenAI Realtime: langsmith[openai] + wrap_realtime() connection proxy. - Gemini Live: langsmith[google-adk] + LangSmithLivePlugin on Runner.run_live, replacing the hand-rolled RunTree/event_span quickstart. - Google ADK: keep the configure_google_adk batch guide; link to Gemini Live for the live voice model. Clarify that the within-trace turn span is a grouping run, not a thread-level LangSmith turn (a separate trace per turn), and reconcile the voice fundamentals guidance. Drop the manual OTLP env vars and download-the-processor steps.

Why
The voice tracing guides told customers to copy a span-processor
.pyfile from the voice-demo repo and wire OpenTelemetry exporter env vars by hand. These integrations are now packaged underlangsmith.integrations(langchain-ai/langsmith-sdk#3107), so the guides should show what a customer installs and imports.Each guide follows the same shape: install, set environment variables, set up tracing, record the conversation audio. The integrations self-configure their LangSmith export from
LANGSMITH_*, so the manualOTEL_EXPORTER_OTLP_*variables and the download-the-processor steps are gone.What changed
trace-with-pipecat):langsmith[pipecat]+configure_pipecat(); audio via Pipecat'sAudioBufferProcessor.trace-with-livekit):langsmith[livekit]+configure_livekit().trace-openai-realtime): onelangsmith[openai-realtime]install, then a section for each way to build the agent:wrap_realtime(full control).wrap_realtime_session(the SDK owns the turn/tool loop).Both import from
langsmith.integrations.openai_realtime.trace-gemini-live):langsmith[google-adk-live]+LangSmithLivePlugin(fromlangsmith.integrations.google_adk_live) onRunner.run_live.trace-with-google-adk): unchanged batch guide, plus a note linking to Gemini Live for the live model.All voice-demo links removed in favor of the packaged-SDK end state.
