Meta has released Muse Voice Transcribe, taking the #1 spot for Final Transcript accuracy on AA-WER Streaming with 3.1% WER at 0.16s after end of speech
Muse Voice Transcribe is the first streaming Speech to Text model developed by Meta Superintelligence Labs. Meta states that the model was trained on more than 70 languages, with 25 extensively verified, and supports audio inputs exceeding one hour without required post-processing. It processes audio in 80ms chunks and is available through the Meta Model API, Meta AI for Mac and Muse Code.
Key takeaways
➤ Final Transcript: Muse Voice Transcribe achieves 3.1% WER at 0.16s after end of speech. It is more accurate and faster than Cartesia Ink-2 (semantic endpoints) at 3.4% and 0.43s, and more accurate but slower than Cartesia Ink-2 (external endpoints) at 4.0% and 0.07s. It is also more accurate, though slightly slower, than ElevenLabs Scribe v2 Realtime at 3.6% and 0.14s.
➤ First Partial Transcript: The model achieves 3.6% WER at 0.13s, just ahead of ElevenLabs Scribe v2 Realtime on accuracy and latency. It is more accurate and faster than Cartesia Ink-2 (semantic endpoints) at 4.9% and 0.17s, and more accurate but slower than Cartesia Ink-2 (external endpoints) at 4.0% and 0.07s.
➤ Price: Muse Voice Transcribe costs $0.18 per hour, or $3 per 1,000 minutes. This is below Cartesia Ink-2 at $4 and less than half the $6.50 charged for ElevenLabs Scribe v2 Realtime and Deepgram Flux.

On First Partial Transcript, Muse Voice Transcribe achieves a 3.6% WER at 0.13s after end of speech, just ahead of ElevenLabs Scribe v2 Realtime on accuracy and latency. Muse is more accurate than Cartesia Ink-2 with external endpoints at 4.0% WER and 0.07s, while trading some speed, and is both more accurate and faster than AssemblyAI Universal-3.5 Pro Realtime, whose Max Accuracy and Min Latency modes achieve 4.0% WER at 0.18s and 0.17s, respectively.
Muse Voice Transcribe is available for $0.18 per hour, equivalent to $3 per 1,000 minutes of audio, below Cartesia Ink-2 at $4 per 1,000 minutes and less than half the $6.50 charged for ElevenLabs Scribe v2 Realtime and Deepgram Flux.
