AI voice translator features

A voice translator has to do more than swap languages, it has to keep the voice itself intact. Here's what that looks like in practice.

Voice cloning

Clone a speaker's actual voice and carry it into 32+ supported languages, so the person your audience already trusts is the same person they hear in the translation.

Multi-speaker dubbing

Translate audio with more than one speaker without collapsing everyone into a single generic voice. Each speaker keeps their own identity across the translation.

AI voice library, with preview

Don't want to clone a specific voice? Choose from a library of natural-sounding AI voices. Preview voices, pick from various audio styles for the output, review the translated transcript, and make quick fixes with editable transcripts.

Export in the format you need

Download translated audio as MP3 or WAV, video as MP4, and subtitles or transcripts as SRT or TXT, so the output slots straight into whatever you’re publishing. Preview the result first and make changes that affect one segment or the whole track.

How it works

How to translate an audio file online

The whole workflow runs in your browser as an audio and video translator online, with editable transcripts before export and nothing to install or configure. Upload, translate, edit if needed, download the translated transcript as SRT or TXT, and export with this audio translation tool.

For volume, the same engine is available through the API.

Start Translating Your Audio

Book a demo

step 1

Upload your audio file

Use our browser-based translator online to upload audio with, using a simple audio drag workflow to choose the source and target language and start translating. Files up to 5 hours long are supported.

step 2

Hear it before you commit

Listen to the same line translated from one language into Spanish, French, Italian, and 135+ other different languages, with the cloned voice carrying the tone in each one, before you use audio drag to upload audio and choose the source and target language yourself.

step 3

Review what needs a second listen

Once your file is translated, Rask flags the segments most likely to need a check, so you're not re-listening to the whole track to catch the one spot worth a closer listen. Play back just the flagged parts, fix them in the editor, and move on.

step 4

Edit, export, and share

Preview and adjust the transcript in the editor, set your glossary and tone once and translate into multiple languages with a single click while everything stays on-brand. In the end export as MP3, MP4, SRT, WAV, or share a link straight to your team or client.

Full control

Make Translated Voice Sound Natural

A translation that gets the words right and still sounds robotic isn't finished. Rask includes an editor to review the transcript for a more accurate translation before export, then translate voice and share the result while preserving the original voice and the speaker's tone across the translation, not just the transcript.

Two separate controls handle this:

Expressiveness

Governs how much emotion and variation comes through.

Similarity & Accent

Governs how closely the output matches the original speaker's identity.

Natural, balanced delivery, keeping the speaker recognizable with a softened accent.

Use cases

Voice Translator Use Cases

One source recording, many languages - with the speaker's actual voice intact. Pick the kind of audio you work with.

01 / 05 · Training & onboarding

Training and onboarding audio

Onboarding sessions, SOPs walked through out loud, and internal training recordings, translated so every region gets the same training, not a locally re-recorded version.

02 / 05 · Courses & education

Course and educational audio

Turn a recorded lecture or course module into a catalog of languages without re-recording it for every market. From the original spoken content, AI audio translators can generate both translated speech and text, which helps a language teacher reuse lessons for multilingual learners.

03 / 05 · Sermons & broadcasts

Sermons and audio broadcasts

Plenty of services already go out as audio only, a radio broadcast, an audio livestream, a sermon podcast feed. Translate that audio directly instead of re-recording it, and keep the speaker's actual voice, so a congregation hearing it in another language still recognizes who's speaking.

04 / 05 · Podcasts & interviews

Podcasts and interviews

Translate a full episode and keep the host's voice and pacing intact, then publish it as its own file on a new-language feed. There's no video track to sync, just the audio, translated.

05 / 05 · Audiobooks & narration

Audiobooks and narrated content

Onboarding sessions, SOPs walked through out loud, and internal training recordings, translated so every region gets the same training, not a locally re-recorded version.

In some countries, a voice can count as part of someone's identity. Rask supports both a consented clone and a neutral synthetic voice, so you publish with the right one.

What people say

THE BEST AI video translation tool

The user interface is exceptionally intuitive, making the entire process ultra-easy for me. I've particularly appreciated Rask's proficiency in handling technical and specialized language commonly found in online courses. The translations consistently maintain accuracy and a natural tone.

Probably the best AI dubbing software on the market right now

It has an easy to use interface where both the original language and the translation can be edited. And the clone voices are quite good. In totality a top tool right now in the market. I'm the host of a local podcast that we would like to internationalize - translating it to several languages and sending it out again using the original voices, now cloned and speaking English.

Great AI software for delivering content worldwide

The most helpful feature is to edit the translated transcript and being able to redub the video. The voice cloning feature is very accurate - that is great for delivering the content of a known guest, that people know how their voice sounds. Now they recognize the voice and understand the message.

A great discovery that saved a lot of work!

The easy straightforward way to use it, the fact to be able to edit the translated text before rendering the final versions - we work with videos that need compliance approval for the text, so for us this is an important feature, together with the fact that the voice cloning is very well achieved. It makes it easier for us to respond quickly to client changes.

Not perfect, but almost...

You don't need any previous knowledge, you just sign up and start translating and dubbing your videos. The possibility to correct the translations helps to get exceptional results. I have done a project of about 30 videos of about 25 minutes each in 2 languages and the results were excellent.

Amazing

I used Rask to translate 18 episodes of a podcast from the original Italian. I cloned my own voice and used library voices for all the other people involved. The result is amazing. My cloned voice sounds like my own voice (with a better accent). Rask allowed me to translate an Italian podcast into English in just 3 days.

AI-based video translation service that breaks down language barriers

The most impressive feature is the AI's ability to maintain the speaker's original voice while translating the content. This is a game-changer for online educators like myself looking to reach a global audience. French being my first language, it was difficult for me to reach students from UK, US, etc. But with this tool, I have access to a bigger market.

Fantastic translation tool with some room for improvement

I'm a Canadian YouTuber who's always wanted to translate my content to the french language. I've used it on a couple of my videos to date, and have to say I'm quite impressed with the cloned voice feature. Planning on using it for 3-4 videos per month to bring my french channel back to life without a huge time commitment.
