SpeechFast, 100% local voice dictation for Mac
SpeechFast (MusCorp), 2026
Read the originalRead on October 25, 2026
- What it is
- The homepage of SpeechFast, a dictation app for Apple Silicon Macs made by MusCorp, a sole trader in France. It describes on-device transcription, the fn-key workflow, the three speech engines, the one-time price and the clean-up step.
- How much weight it carries
- The maker's own marketing page, so it is the authority on what the app claims, not an independent test. Its privacy statements are repeated in the maker's legal page, which is cited separately. The page does not give the speech engines' accuracy except in the maker's own test figures.
