Meta prices Muse Voice Transcribe at $0.18 an hour, with real-time diarization for 20+ speakers: a steal for enterprises?

Meta’s Muse Voice Transcribe streams transcription, endpoint detection, and speaker diarization for up to 20 participants at $0.18 per audio hour, handling hour-long clips and seamless multilingual code-switching. Trained on 70+ languages (25 fully validated), it processes 80 ms audio chunks with adaptive delay and reinforcement-learning rewards to balance word-error-rate and latency, exposing diarization as a first-class mode with turn-level timestamps and session-wide speaker labels.
