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.
01

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.
02

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.
03

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.
04

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.

AI Audio Translation Overview

Rask is an AI audio translator and video localization platform designed for teams running an ongoing content operation - from in-house localization and marketing teams to enterprises scaling into new markets. It translates spoken audio into 135+ languages, preserving the original speaker's voice through voice cloning or synthetic voice presets.

This eliminates the need for costly studio sessions or re-recordings, enabling faster localization and publishing in the audience's language while maintaining high perceived quality.

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.
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.
Speaker 1
Voice clone
62%

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.
Enterprise ready

Built for enterprise-grade security

“Speaker ID and voice cloning in one platform”

I love that this platform can identify different speakers and clone voices to create customized content - the interface is user-friendly and onboarding was quick and secure.

“It sounds even better than the real me”

I cloned my own voice for my podcast, and it honestly sounds like me - just with a better accent than the original.

“Probably the best AI voice cloning and dubbing tool on the market”

Very easy to upload voice or video files, with an interface where both the original and the translation can be edited. The clone voices are quite good - in totality, a top tool right now.
