Workout Videos in Your Clients’ Language: Native AI Voices for Trainers

During a hard interval nobody reads the screen. People listen for the next move while they catch their breath, so the spoken cue does the work the on-screen name cannot. In a second language, a quick “Next: hip thrusters” is easy to miss; in your own, it lands at once.

It also widens who you can coach. A trainer in Madrid with a German-speaking client group, a studio in Tel Aviv coaching in Hebrew, or an online coach selling in Japan can give each audience videos that speak to them, without hiring voice talent.

Fit Cut Pro offers two kinds of AI voice. Native-speaker voices sound like a native speaker of your language, for example a Hebrew, Spanish or German speaker, and appear in their own Native voices section for the language your app is set to. Multilingual voices are natural AI voices that speak whichever language you type.

For short coaching lines, native voices usually win: exercise names and quick cues such as “Rest” and “Next” are exactly where accent and stress give a non-native voice away. Multilingual voices are the better choice when you publish in more than one language and want the same voice in each. Play a few of both with a real line before you voice the whole library.

The 16 app languages are English, Spanish, Portuguese, French, German, Italian, Polish, Hungarian, Greek, Russian, Hebrew, Arabic, Japanese, Korean and Chinese (Simplified and Traditional).

Set the app language to your clients’ language, then open the Voice side tab and the Voice studio. On the Voice tab, pick a native or multilingual voice. On Trainer cues, the default wording follows your app language; Set up basic cues with this voice creates every missing trainer cue at once, free in a stock voice. On Exercises, Voice all exercise names voices every clip that has no name line yet, in one request.

Name your clips in the same language and use the same words in each spoken Name line, so what clients see on screen and what they hear match. In the AI Editor this also matters for matching: a clip’s lines play when its name matches the exercise name on the cue.

Every clip has an Info line: a form tip of up to 15 seconds, played once per workout at that exercise’s first set. On Pro and Ultimate, the ✨ button writes it for you in your app language, sized to fit 15 seconds, at no credit cost. Check it the way you would check a new coach’s cueing, adjust the wording to how you teach, then generate it in your chosen voice or record it yourself.

On Pro and Ultimate you can also create an AI voice from your own. You read a script of about 90 seconds once, in your app language, after an explicit consent step; the AI then speaks your cues in your voice. Only your account can use it, it is never used to train AI models, and you can delete it at any time, which also deletes the recordings and every line made with it.

AI voice lines need a paid plan and cost 1 AI credit per started 250 characters per request.
