Why professionals get Pro
VoiceStudio is free and open source. Pro is the closed-source build for professionals: more devices, new features first, and a licence you can show.
Screens from the project README, captured from the development build.
Everything here is in the free app.
No seats, no trial, nothing on this list behind a paywall.

Voice cloning
Drop in a short clip and it mirrors the voice. Three seconds is usually enough.

Voice design
Build a new voice from a sentence: gender, age, accent, pitch, emotion.

Video dubbing
Transcribe, translate, re-voice. Every speaker keeps their timing.

Studio
Write a script, pick a voice, and synthesize on your own machine.

Voice gallery
Ready-made designed voices, browsable by accent, age and style.

Local API
OpenAI-compatible audio on port 3900, every route documented.
Free and Pro, side by side.
Free is open source. Pro is a separate, closed-source build that adds more.

Why pay for free software?
Three reasons to start with.
A licence you can show
A document for the client or legal reviewer who asks, instead of a link to an open-source licence.
One seat, three machines
Up to 3 registered devices, 3 running at once. No account needed to run the app.
A full refund, no questions
Not for you? Say so within 7 days. See refunds.
