Hi everyone! I'm currently working on a home automation project at my University. Right now, we would like to use some TTS API in order to read some data from sensors. This API can be online, as the Pi will be connected to the internet.
I searched for some alternatives like Festival ou Pico TTS, but the overall voice quality is not so good. And as we are from Brazil, if possible, we would like something that works with portuguese (Pico does not support).
Amazon has Polly, and Google also has their own API, which are very good, but from what I saw, they are all paid and don't have specific licences for developers with non commercial purposes. So I would like to know if you guys can recommend any APIs or softwares for that. If possible, we would love them to be free and able to speak portuguese (if not possible, we will be happy with english!!). We just want a natural voice and one that should be free for non commercial purposes. Also, we are using Node JS in our application, so if there is anything specific for it, it would also be great!
Thanks, Igor!

Re: Text to Speech in Raspberry Pi
Google speech is free for low use (max amount of speech to text conversion per month) this is what is used with the RPi AYI project, I have used it myself. Of course you need to have internet access to upload the sound to google to get the conversion. I have seen some speech to text converters that you can down load and run on the RPi (don't have a link but have seen them) but google is rated as the best for good quality conversions
