Best TTS extension ever used

It's Fantastic. Use full addon. It support Sinhala language also.

Awesome add on! Only issue is that I cannot sign in to access Premium voices.

It's hands down the best TTS extension that I ever used. Too bad it doesn't work in private browsing mode. Hopefully it can be fixed.

I've tried more than 5 different TTS addons, but none of them functioned as well as this one. Both English and Turkish is being read alout quite well and without any hussles. The initiation and ending of the reading is very intiuitive and works just fine.
I definitely suggest trying out this addon.

Esta muy buena la app, se lee rapido y con muchas opciones

This is a excellent add-on. I am Chinese and I can read English but I read very slow. With this add-on, I can read faster and can understand some of the words I do not know. The add-on also give us a lot of voice choices including man and woman voice.

The TTS (multi-language tts) worked well enough but stopped reading PDFs as FF was updated and the developer perhaps gave up. This add-on reads my PDFs beautifully and all the controls work perfectly. Thank you. Thank you.

Great usability. Amazon voice "Kimberly" sounds the best to me. Very listenable.

Yeah i like how it highlights. This Text to speech FF addon is awesome!!! Yay!

This is an awesome addon and is free/libre software
