How it works

Your voice, cloned in three steps

A clean sample is all it takes. Rask reads your tone, pacing, and accent, not just the words.
Step 1

Upload your video

A sample you want to translate, the cleaner the recording, the closer the clone.
Step 2

Adjust similarity & expressiveness

Dial in how close it stays to the original voice and how much emotion carries through to keep your authenticity.
Step 3

Export in any language

Preview, download, and publish, without hiring a single extra actor
Voice cloning technology carries the identity of who’s speaking and the emotion behind it into every language, preserving the speaker’s unique characteristics so content stays authentic, not like a dub. It also carries over pacing, tone, and delivery style across languages, which is why teams use it for multilingual video localization when trust depends on hearing the same person.

Educational content

One instructor, every course, every language, without a single re-record.

Internal training and L&D

One video library for onboarding, help content, and training your whole team can trust.

Religious broadcast

The same trusted voice, every week, in every language your congregation speaks.

Product marketing and demos

Your marketing videos and demos in every market, without a reshoot for every language.

Founder- or expert-led content

The founder’s own voice and speaking style reaching a new market, trust a hired actor can’t fake.

When you don't need it

No specific person to recognize? Natural AI voiceovers or a neural voice usually work fine for simple translation, explainer narration, or other low-stakes jobs where teams need fluent speech.

“The voice clone was the moment.
Suddenly I could be in 4 languages without hiring 4 actors.”

Full control over the clone

Similarity and expressiveness are separate dials, so the same clone can carry full identity or just the tone — with accent smoothing for non-native speakers, control over speaking speed, and tuning for a professional voice.
Expressiveness
Dial emotion up for energetic content or down for steady, stable narration.
Similarity
Keep the speaker's exact identity close to the original, or blend toward a cleaner, neutral tone.
Accent smoothing
Soften a non-native accent without losing the person behind it.

Our technology

How the technology works

Rask uses machine learning and deep learning to analyze your sample for pitch, tone, speaking rhythm, voice characteristics, speech patterns, and the acoustic fingerprint that makes your voice yours. In this cloning process, an advanced AI neural network turns those signals into a digital voice model, which is how AI voice cloning technology enables voice generation and produces new speech in the target language, at the pace and emotion you set with Similarity and Expressiveness.
Your data stays encrypted in transit and at rest, with keys rotated at least yearly. Rask is SOC 2 Type II certified and GDPR compliant.

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.
