BanghuaZ · x · 2026-07-12
OpenMOSS has released MOSS-Transcribe-Diarize, an open-source 0.9B model under the Apache 2.0 license.
This model combines transcription, diarization, and timestamping into a single pass, with its core advantage being suitability for long audio inputs.
The provided real-world test case involves:
- Processing 174 hours of Apollo 11 mission audio into searchable content
- A total cost of just $9.46
- Using original NASA recordings preserved by the Internet Archive
- Processing a total of 103 audio segments
- Completion via a single Hugging Face Job in 3.8 hours, at a speed of roughly 47x realtime
- Generating 45,355 timestamped speaker segments
The author notes that users can now search these mission recordings by "who said what and when."
