I want a text-speech API that works over the web. Google Translate unofficial API doesn't fit because I need to read more than one paragraph and they're limited to 100 chars.
I checked iSpeech, but they require a telephone call to buy credits and since this work maintainers do not speak english and this type of billing/selling is pretty ridiculous, I'm looking forward for another alternative.
Anyone?
EDIT: It must have an pt-BR voice.
I was searching for the exact same thing, I needed pt-BR voice too, and I have just quit using Google TTS because it has got some limitations, bugs (with sentence punctuation endings) and no documentation at all.
I found http://www.voicerss.org/
It works good for me, it's free, simple API and has the Brazilian pt-BR voice we need.
