The integrations capture full conversation audio, STT/TTS latency, interruptions, tool calls, voice activity detection events, and more in a single trace tree. Both 'sandwich' (STT → LLM → TTS) and speech-to-speech architectures are supported, giving teams the same review and debugging workflows available for text-based agents. Each integration requires only a few lines of Python to set up. ## Full article daily.dev links to this article rather than hosting it.
