Addressee detection for voice agents: device-directed speech detection that runs before STT, so background speech, side conversations, and the agent's own TTS echo never trigger it. No wake word, model-agnostic, drop-in for LiveKit, Pipecat, ElevenLabs, Twilio, and OpenAI. The layer your VAD and turn detection are missing.
Why this job: says: tts; topics: voice-assistant, voice-ai
What it does
A voice agent's microphone hears every voice in the room: yours, a coworker's, the kids, a podcast playing on the laptop, the agent's own TTS bleeding back through the speakers. Most pipelines respond to any of it, paying STT for every transcribed second and triggering the LLM on speech that was never directed at the device.
