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

Fantastic.

So good! highly recommended!

Simple to use, just select your webpage text (including web-based emails), right click and click on "read aloud". Excellent choices of voices in the settings as well. A great and useful tool, definitely a keeper! Many thanks!

App simples! Voz bem sintetezida!

Works well. I use Alex and slowed the natural speed down a bit and it's perfect! Please keep it up!
