AI Voiceover Studio
26 neural voices — offline on Mac
Turn any script into broadcast-quality narration without leaving your Mac. 26 voices, emotion transfer, voice cloning, SSML control — all running locally with zero internet dependency.
What's included
26 Neural Voices
Male, female, and neutral tones across American, British, Australian, and multilingual accents. Each voice is a full neural network running on your Mac's GPU.
Emotion Transfer
Adjust warmth, authority, and energy per sentence without changing the voice. Make narration feel conversational, authoritative, or empathetic — by adjusting a slider.
Voice Cloning
Provide a short recording of any voice. Vosuba creates a local voice model that synthesizes new speech in that voice. Your samples never leave your machine.
SSML Control
Fine-tune pronunciation, pauses, emphasis, and speaking rate with SSML tags. Essential for technical content, product names, and multilingual scripts.
Multi-Format Export
Export to WAV (broadcast-quality) or MP3 (web-ready). Or burn the voiceover directly into your video alongside styled subtitles — all in one export pass.
Subtitle + Voiceover
Generate subtitles and voiceover from the same project. Vosuba auto-syncs the narration with your caption timeline for a polished, accessible final video.
Use cases
YouTube Narration
Create channel intros, explainer voiceovers, or full narration tracks without hiring voice talent. Generate unlimited takes with different styles.
E-Learning & Courses
Produce consistent, clear narration for online courses, LMS modules, and training videos. Update scripts without re-recording.
Podcast Intros
Generate professional-sounding show intros, sponsorship reads, or segment transitions. Export as MP3 and drop into your podcast editor.
Internal Communications
Create narrated announcements, onboarding videos, and compliance training — using an offline tool that keeps sensitive content private.
Frequently asked questions
Does the AI voiceover require internet?
No. Vosuba's voiceover engine runs 100% offline on your Mac using on-device neural network inference. No audio is sent to any server — ever. This makes it suitable for confidential scripts, internal training materials, and pre-release content.
How many voices are included?
Vosuba Pro includes 26 neural voices spanning male, female, and neutral tones across multiple accents (American, British, Australian, and more). Each voice supports emotion transfer — you can adjust warmth, authority, and energy without changing the voice itself.
Can I clone my own voice?
Yes. Vosuba Pro includes voice cloning that works entirely on your Mac. Provide a short sample recording, and the system creates a custom voice model for text-to-speech generation. Your voice data never leaves your machine.
What audio formats can I export?
Vosuba exports voiceover audio in WAV (uncompressed, broadcast-quality) and MP3 (compressed, web-ready). You can also burn the voiceover directly into your video alongside styled subtitles.
