Frequently asked questions

Which languages does UltiVoice support?
UltiVoice supports 50+ languages for both transcription and dubbing, including Vietnamese, English, Chinese, Japanese, Korean, Spanish, French and many more. See the full list in the documentation.
How good is the voice cloning quality?
Our TTS system uses F5-TTS and Whisper large-v3 to produce natural-sounding speech. Quality depends on the length and cleanliness of the sample audio — we recommend at least 30 seconds of clean audio.
Does UltiVoice work without an internet connection?
Yes. All AI models (Whisper, F5-TTS, translation) run entirely locally on your machine. No internet connection is required after installation and license activation. Your data never leaves your device.
Which video/audio formats are supported?
Input: MP4, MKV, AVI, MOV, WebM and other FFmpeg-compatible formats. Output: dubbed MP4 video + SRT/ASS subtitles. Supports YouTube URLs and popular video services.
How does licensing work? Can I use it on multiple machines?
The Pro license allows 1 machine (hardware-bound). The Studio license allows 3 machines. Licenses are validated via HWID and can be transferred through the account management portal.
Is macOS or Linux supported?
UltiVoice currently supports Windows 10/11 x64. macOS and Linux support is on the roadmap — follow the blog for updates.
