// how it works
How it works
- Pick the job
Transcription, synthesis, voice changing, or editing — each tool here majors in one.
- Install and set up
Binaries, pip packages, or Docker; models download on first run for AI tools.
- Feed it audio or text
Drop in a recording or type what you want spoken.
- Export the result
WAV/MP3/OGG outputs drop straight into editors or apps.
// features

Questions, answered
Who maintains speechbrain?
It is an open-source project at speechbrain/speechbrain with 1,730 forks. Check the repo's contributors and recent commits to see how active maintenance is.
Is speechbrain free for commercial use?
Apache 2.0 licensed — commercial use allowed with attribution.
Can I use the voices commercially?
Check each license — many allow it, but voice-cloning has ethical and legal boundaries.
How accurate is the transcription?
Whisper-class models rival paid services on clear audio; noisy recordings need cleanup first.
Which languages are supported?
Dozens; English is strongest, major world languages are solid.
