Frequently asked questions
What is speech to speech AI?
Speech to speech takes a spoken recording as input and produces new speech as output. In MCV Labs, re-voice mode transcribes your recording and speaks the same words with a different AI voice.
Does it keep my tone and emotion?
Re-voice keeps your words, language and timing, but the delivery comes from the AI voice you choose — it does not copy your exact intonation.
How long can the recording be?
Up to 60 seconds per file on the free plan and longer on paid plans (up to 20 minutes on Pro and Business), with files up to 25 MB.
Can I translate at the same time?
For translation into another language, use AI dubbing, which also gives you subtitles.
