What is HeyGen?

HeyGen's strongest capability is video translation: upload a video and it dubs the speech into another language with lip movements resynchronised to the new audio, keeping the original speaker's presence. Alongside that it offers talking avatars generated from photos and script-driven presenter videos, with voice cloning for multilingual consistency. Marketing, training and content teams use it to make one recording serve ten markets. Because it clones real people's likeness and voice, it enforces consent verification - which reputable organisations should treat as a feature.

FAQ

Can I clone someone's voice without their permission?

No, and this is enforced through a verification step. Creating someone's likeness without consent violates the terms and, in many jurisdictions, the law - including publicity and biometric privacy rules.

How good is the lip sync really?

Among the best available. It holds up well for standard presenter footage, though extreme angles, rapid speech and heavy facial hair reduce quality.

Does translated video keep the original voice?

You can keep the speaker's cloned voice while changing the language, which usually preserves more credibility than substituting a generic voice actor.
