Change the voice in a video with AI
Replace the voice in your video or edit what is said, and AI voices the new lines in the same voice. No translation and no reshoot: same language, music and background stay.
A new voice or new words, no reshoot.
One video, three versions
Play the video and switch versions: it continues from the same moment. The example is in Russian — listen to how the voice and the edited line change.
Original
As filmed: the author’s own voice.
New voice
Same words, spoken by a library voice, with lips matched by lip sync. Music and editing stay.
New words
The author’s voice, but the second line is different. Only that line was re-voiced, with the lips matched:
Teplitsa of Social Technologies, “How to shoot video on a phone”, CC BY. Re-voiced with Speeek.
What you can change
Upload the video, then change the voice and text in the editor.
A different voice
Male or female, standard or premium. Listen to each voice before choosing.
New words, same voice
Got a number wrong or the price changed? Edit the line and only that line is re-voiced.
Your own voice
Record a minute of your speech and a video voiced by a narrator will speak in your voice. Saved voices come with Pro.
When it helps
A reshoot means lights, camera and takes all over again. Re-voicing takes a few minutes.
Bad audio or you don’t like the voice
Recorded on a phone, noisy room or the voice sounds unsure: replace it with a clean narrator voice.
A price changed or a number is wrong
Ads, product reviews, tutorials: fix the line in the editor instead of filming again.
A course is out of date
The interface or a rule changed: update a few lines in the lesson and keep the rest as it was.
Need another language?
That is video translation: AI translates the speech into any of 43 languages and voices it in the speaker’s voice.
FAQ
Is it free?
The first minute of every video is free, no card needed. After you sign in it is voiced in the speaker’s voice; you pick another voice or edit the text in the editor, and re-voicing a line uses minutes as usual. The full video and downloads require a subscription: Start from $5 for 5 minutes, Pro from $15 for 10 minutes.
Which voices are there?
29 voices in English: 12 standard voices on every plan and 17 premium voices from Pro. You can listen to each one before choosing. On Pro you can also save your own voice from a recording.
Can I change just one line?
Yes. Edit the line in the editor and re-voice it: only that line is voiced again, in the same voice, and the rest of the video stays as it was.
Will the music and background stay?
Yes. AI separates speech from music and sounds, replaces only the speech and puts the video back together.
Will the lips match the new words?
Turn on lip sync (from Pro) and AI redraws the lips to match the new speech, as in the example above. Without lip sync only the audio changes.
What if there are several people in the video?
AI separates up to 5 speakers, each with their own voice. On Start one voice covers the whole video; different voices per speaker come with Pro.
Which languages does it work with?
Any of 43 languages: the video language and the voice-over language are simply the same. If you need another language, that is video translation, on the home page.
