Meta has launched Muse Voice Transcribe, a real-time speech-to-text model priced at $0.18 per hour of audio that combines transcription, speaker diarization for 20+ speakers, and endpoint detection in a single model. The system supports over 70 languages, with 25 extensively validated for release, and handles multilingual code-switching without separate post-processing. While competitors like Speechmatics support higher speaker counts (up to 100), Meta's combination of low latency, high-capacity diarization, and aggressive pricing targets enterprise developers building meeting systems, call analytics, and ambient AI applications.
