VoiceStudio
VoiceStudio is an open-source voice AI studio for local voice cloning, voice design, video dubbing, dictation, transcription and audiobook creation. Users can describe a voice by gender, age, accent, pitch and emotion without providing reference audio. Its dubbing workflow transcribes and translates video, then re-voices it while keeping speakers separate and aligning timing with the original. Users can create multi-voice audio from scripts and chaptered audiobooks from long text or EPUB files. The desktop app exposes a local OpenAI-compatible API for speech, voices, transcription and dubbing. The maker lists 26 adapters, including local text-to-speech and transcription engines and a configured-remote ASR adapter. The maker says recordings, generated audio, transcripts and derived voice data stay on user-controlled storage and are not received by its website or control plane. The app may access the network for updates, model downloads or explicitly network-backed adapters. The public build has no hosted dashboard or Cloud API. Open Source costs nothing under AGPL-3.0; Pro costs $99 a year and Lifetime costs $299, paid once. Speech model licences are separate.
