AnyToSpeech

AnyToSpeech has a free plan, but it is tight: about 15 seconds of audio, 200 characters, one audio file per day, no commercial use, and a 'Created with AnyToSpeech' tagline on the output.

AnyToSpeech is an online text-to-speech converter that turns text into spoken audio with natural-sounding voices and supports multiple output formats.

Paid plans remove the restrictions.

The $14 plan gives 100,000 characters, roughly 100 minutes of audio, with commercial use, no tagline and no daily limits.

The $69 plan raises that to 1,000,000 characters, about 16 hours of audio, and the same terms.

Each audio can use the full character allowance on both paid tiers.

The free tier works for testing a voice.

For voice overs, narration or anything you publish commercially, you will need a paid plan.
