Muse Voice Transcribe
Vintage: 2026-09. Primary evidence is Meta's official post Introducing Muse Voice Transcribe dated September 1, 2026, as hydrated in 2026-09-02-grok-com-ai-news-digest-2026-09-02-fable-5-1-astra-atlas-g20. Recap treated this as incremental / slightly outside the 24-hour window; the issuer date is inside that window.
Muse Voice Transcribe
One-line summary: Meta Superintelligence Labs' September 1, 2026 real-time audio perception model — streaming ASR, 20+ speaker diarization, endpointing; 70+ languages (25 extensively verified). Recap timing that put it outside the last-24h window is wrong.
What it is
Meta's first real-time audio perception model from Meta Superintelligence Labs. Official post (September 1, 2026): streaming ASR, diarization with 20+ speakers, endpointing; trained with 70+ languages of which 25 are extensively verified; ships via Meta Model API, Meta AI for Mac, and Muse Code.
Why it matters to this thread
Audio / voice models are in-scope under multimodality. The digest recap de-emphasized this as "more incremental or slightly outside the strictest 24-hour window." Issuer date is September 1, 2026 — in-window. File the timing correction; do not adopt the recap's de-emphasis as fact.

What this source does not establish
- Recap "incremental / outside 24h" is false on timing. Issuer date is September 1, 2026.
- Not a Gemini 3.5 Transcribe claim and not a rewrite of gemini-3-5-transcribe (DeepMind product-account color).
- Not muse-spark. From 2026-09-07-weekend-x-ai-meta-aira3-kaggle-gold-openai-wiki: Muse Spark 1.3 max is a coding/agentic model line. Different product.
- Not rumik-oss-1. From 2026-09-08-x-morning-buckmaster-alpoge-ai-fluid-proofs-openai-credit: Rumik OSS 1 is Indic TTS (open weights, CC-BY-NC). Adjacent audio only — not a Transcribe rewrite.
- No WER table, pricing, or parameter count in the hydrated digest.
- No ticker or 8-K.
Open questions
- How does Muse Voice Transcribe compare to gemini-3-5-transcribe on noisy IDs / filler-word removal / language coverage? This source does not say.
