AI voice cloning — your voice, any language
DubSync clones your voice with AI and speaks it fluently in 30+ languages. Your tone, your cadence, your personality — preserved across every dubbed version.
How voice cloning works
Analyze the original voice
DubSync's AI listens to the source audio, isolating vocal characteristics like pitch, timbre, speaking pace, and emotional tone from background noise and music.
Build a voice profile
The system creates a neural voice model that captures what makes the speaker's voice unique. This profile drives all downstream translations.
Synthesize in target languages
Using the voice profile, the AI generates speech in each selected language. The cloned voice preserves the speaker's identity while achieving native-level pronunciation.
Refine timing and emotion
The output is automatically adjusted so speech duration matches the original video. Emotional inflections like excitement, emphasis, and pauses are carried over.
Key capabilities
High-fidelity cloning
Our model captures over 40 vocal parameters per speaker, producing output that listeners consistently rate as indistinguishable from the original voice.
Adjustable fidelity
Choose between Standard and Ultra voice cloning. Standard is fast and suitable for most content. Ultra delivers maximum accuracy for professional productions.
Ethical safeguards
Voice cloning is restricted to content you own or have rights to. All cloned output is watermarked with an inaudible digital signature for traceability.
