HeyGen Dubbing — translate video into over 100 languages

What HeyGen is

HeyGen is a platform for creating video with artificial intelligence, known above all for two things — generating AI avatars that speak a script you give them, and dubbing (translating) video into many languages. The point is for one filmed video to sound natural in another language, with no reshoot, no actors and no studio.

HeyGen's strength is exactly that realistic dubbing — the speech is not just translated, it is spoken in the voice of the original speaker, with lips that match the new language. That makes the translated video convincing, as if the person really were speaking that language.

In genkiki.com the HeyGen dubbing feature is available — for fast, natural localisation of a finished video into dozens of languages.

Versions and capabilities in generiram

In generiram, HeyGen runs in the Video → Video mode under the name “HeyGen Dubbing (translation)”. You supply a finished video and pick the target language, and the system performs a full dub.

VariantModeWhat it is for
HeyGen Dubbing (translation)Video → VideoFull dubbing — translates the speech, clones the speaker's voice and reshapes the lips to the new language

The dubbing is “full” in three simultaneous steps: it translates what is said into the language you chose, clones the voice of the speaker so the translation sounds like the same person, and reshapes the lips so their movement matches the new speech. Over 100 languages are supported, Bulgarian among them.

There are extra settings too, depending on what you need:

  • Audio only — translates and voices the speech but does not reshape the lips (when the new sound alone is enough).
  • Number of speakers — for videos with more than one person, so the individual voices are recognised and voiced correctly.
  • Dynamic length — lets the running time adapt to the translated speech.

Video up to about 8 minutes long is supported.

What it is good for

  • Localising video into many languages while the speaker keeps their natural look.
  • Translating marketing, training and presentation clips for an international audience.
  • Reaching new markets without reshooting and without hiring dubbing actors.
  • Translating podcasts, interviews and lessons in the speaker's original voice.

HeyGen Dubbing (translate)

videovideo
Aspect ratios: 1:1, 9:16, 16:9 Lengths: 5 sec, 10 sec Price: 101 credits

Strong at

  • It TRANSLATES video into over 175 languages and matches the lips to the new language
  • It clones the speaker’s voice — tone and manner carry over into the new language
  • It doesn’t glue sound onto a mouth: it predicts how a real native speaker moves the muscles for each word
  • Lip accuracy between 85% and 95% on the widely spoken European languages
  • It reads the text off the recording with over 97% accuracy when the sound is clean
  • One filmed video goes out to many markets without another shooting day

Weak at

  • Tonal languages (Chinese, Thai, Vietnamese) and Arabic show a visible lip lag
  • Humour, idioms and wordplay barely translate — a human has to go over them
  • Specialist terms (medicine, law, engineering) need a glossary or a manual fix
  • It wants clean sound, a face to camera and one speaker per scene

Don't use it for

  • Don’t run it on a recording with noise, overlapping voices or a heavy accent
  • Don’t use it on text full of wordplay without a human going over it
  • Don’t rely on it for legal or medical text without a check

Typical tasks

  • Launch your ad in another market
  • Translate a training video
  • A multilingual version of the same address
  • Dubbing a talking head
