Resonant 1 Realtime

by Reson8

Resonant 1 Realtime streams live transcription from 16 kHz audio over a WebSocket, with interim results, speaker labels and custom vocabulary. With semantic turn detection it runs on Reson8 Turns, which signals the end of a speaker's turn for voice agents. Opper lists it temporarily for verification and will retire it when Rumble 2 is live.
