AI voice generator FAQ
How does the AI voice generator work?
Type or paste your text, choose a voice, and FATTLY converts it to speech with natural intonation and pacing. Preview the result, adjust if needed, and download the audio file. Everything runs in your browser at fattly.app — there is nothing to install and no recording equipment required.
How much does it cost?
Fattly runs on pay-per-credit pricing, and your credits never expire. You start with 10 free credits and no card required, so you can generate voiceovers before paying anything. A subscription is optional if you create at scale, but you are never locked into a monthly plan to use the tool.
Can I clone my own voice?
Yes. Alongside text-to-speech with many ready-made voices, FATTLY lets you create a custom, cloned voice from a sample. Use it to keep one consistent, recognizable sound across every video, ad, and episode you publish — ideal for personal brands and channels that want to stay on-voice everywhere.
Can I use the voiceovers commercially?
Yes. Audio you generate can be used in commercial projects — ads, YouTube monetization, client work, e-learning, and more — within the Fattly Terms. Download the file and drop it straight into your editor. Because credits never expire, you can produce and license work on your own schedule.
Which languages are supported?
The AI voice generator speaks multiple languages and accents, so you can voice content for different markets from one place. Write your script in the language you need, pick a matching voice, and generate. It is ideal for creators localizing videos, ads, and social clips for international audiences.
