Tip: a mood cue like [whispering] carries through the text until your next cue (or [/mood] to turn it off) — the voice performs it, it never reads it aloud.

Frequently asked questions

Is this free?

Yes. Guests and free accounts can generate up to 5 times per calendar month (up to 500 characters each). After that, upgrade to a paid plan.

Do I need to create an account?

Not for your first free generations each month. When you hit the limit, upgrade to keep generating longer scripts.

Is this the real person's voice?

No. These are AI recreations for entertainment. They are not affiliated with, verified by, or endorsed by the people named on each page.

Can I clone my own voice?

Yes. Use Voice Cloning on AnyToSpeech to create a custom voice from your recordings (paid plans).

Can this voice speak other languages?

Yes. Paste text in Spanish, French, Portuguese, Japanese, or another supported language and generate. If the language cannot be detected, it falls back to English. English is usually the most natural match because these voices were created in English.
