Voice

community

Phone-call agents — Pi takes the call, transcribes, responds via TTS, hangs up. SIP/Twilio backed.

Voice is the experimental edge of openclawOS. Pi can answer phone calls — transcribe what the caller said, generate a response, speak it back, hang up.

Setup

  1. Twilio (or any SIP trunk) routes calls to your Gateway’s voice webhook.
  2. openclawOS handles call lifecycle: answer, stream audio to Whisper, stream Pi’s reply to TTS.
  3. Voice quality depends on your TTS choice (ElevenLabs, OpenAI TTS, local Coqui — all supported).

Status

Experimental. Latency is the hard problem (~800ms round-trip best case). Useful for after-hours triage, simple Q&A, FAQ-style flows.

Run Voice through your own Pi.

Install openclawOS, pair this channel, message your agent. The whole loop is under five minutes.
