Ask HN: Are there any Text-to-Speech API with free credits?

FakeYou has a public API, but its limited to 10 seconds of speech at a time (and not super fast): https://fakeyou.com/

I haven't tinkered with TTS for some time, but I recall two options:

1. Web Speech API, AFAIK it is supported by most browsers.

2. Turning on text-to-speech in Android phone/tablet settings.

Thanks all for comments.

I found responsivevoice.org which seems good for my experiment.
