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.”

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

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.
