Voysum · Audio transcription
Voysum demonstrated remarkable cloud processing speed in the 38.86s English speech benchmark, completing transcription in 3.85 seconds with 6 export options including TXT, SRT, VTT, and JSON. However, the transcript omitted the mid-section between 13s and 30s, yielding a 63.2% word accuracy; the free tier offers 120 minutes/month with zero export watermarks.
