Voice Agent observability with LangSmith
Google ADK voice agents using Gemini Live can be traced with LangSmith for production observability
“To take that agent to production safely, you need visibility into what your agent is doing and the ability to test its behavior in a number of different scenarios that it might encounter with real end users.”
A Google I/O session demonstrated integrating LangSmith observability tracing into a voice agent built with Google ADK and the Gemini Live speech-to-speech model. The demo highlights that Gemini Live's native audio pipeline (no text transcription step) delivers lower latency and more natural voice, but requires external tooling like LangSmith to gain visibility before shipping to production. This is a practical engineering workflow signal showing Google ADK and LangChain tooling converging around voice agent observability.
