AI video translator
Translate any video into another language in one pass. SaydiVoice transcribes the original speech, translates it in context, then voices the translation with a natural AI voice that fits the original timing — so a video can reach an audience that does not speak its language.
What you get with AI video translation
What is AI video translation?
AI video translation takes a video recorded in one language and produces a version in another. It combines three steps that used to be separate jobs: speech recognition to write down what was said, machine translation to convert that text into the target language, and speech synthesis to speak the translation aloud. Doing all three in one pipeline is what makes it possible to publish the same video to several language markets without booking a studio or a voice actor for each one.

How to translate a video
- Upload the video you want to translate.
- Pick the source and target language, then review the transcript and translation.
- Choose the voice for the target language and render the translated video.
What happens to a video when it is translated with AI?
The video is transcribed, translated and re-voiced. Speech recognition writes down what was said, the transcript is translated at sentence level so the meaning and tone survive, and speech synthesis speaks the translation in a voice you choose for the target language. The finished file is a video with a new audio track, ready to publish to an audience that speaks that language.
Why does translating a video need more than a translator?
A translated script on its own is not a usable video. The new lines have to fit the time the original lines occupied, and they have to be spoken by a voice that suits the content, otherwise the result sounds rushed, flat or out of step with the picture. An AI video translator combines recognition, translation and speech synthesis in one pipeline so those three problems are solved together rather than handed between separate tools.
Can one video be published in several languages?
Yes, and that is the main reason to translate a video rather than record it again for each market. The same source file can be run through the pipeline once per target language, with a different voice chosen for each, so a single recording becomes a set of localized versions without booking a studio, a translator and a voice actor for every language.
Video translation questions
How much does video translation cost on SaydiVoice?
The free plan includes 5 minutes of video translation per month. Paid plans increase this to 20, 30 or 150 minutes a month depending on the tier, and business plans can be arranged for higher volume.
Which languages can I translate a video into?
SaydiVoice generates speech in 32 languages, so a video can be translated into any of them, including English, Vietnamese, Spanish, Portuguese, French, German, Japanese, Korean, Chinese, Hindi and Arabic.
Is the translation done word by word?
No. The transcript is translated at sentence level so the meaning, tone and idioms survive the move into the target language, which is what makes the result sound natural rather than literal.
Will the translated video be the same length as the original?
The translated speech is fitted to the original segment length, so each line lands roughly where it did in the source. This keeps the video's pace and avoids the audio running ahead of or behind the picture.
Can I review the transcript before the video is rendered?
Yes. The transcript is produced first and is editable, so you can correct names, jargon or mis-heard words and fix the translation before spending time on the render.
What output formats do I get?
The translated video is delivered as MP4 with the new audio track. You can also export the generated speech on its own as MP3 or WAV if you only need the audio.
