I tried this add-on on some ebooks out of curiosity, and was pleasantly suprised by how well it performs.
The ability to change the speed and pitch are very nice.

It's very awesome but too bad that it doesn't support Persian language.

Very cool people behind the proyect, useful add on to learn languages

The default voice is garbage, but once you get the google voices setup, this thing works amazing. Can't believe how good TTS has become over the years. Thanks for the addon!

Great tool!

Absolutely brilliant!

It stopped working :(

Bien

Thanks dev , 5 star raring to keep you motivated and also supporting my country language.

Excellent add-on. It help me ALOT in my daily life when searching, reading, learning or reading the news (have Autism 1/Aspberger and ADD).

I gain alot from varieing with this app and reading what I can myself the 'normal' way.

1. This add-on is awesome. The best way to us it is to mark what you want to read up and then right click and select the add-ons icon "Read Aloud".

2. The second way to use it is to just click on the icon in your browsers right corner and it will read EVERYTHING on the page you have open in front of you :)

The only main problem with the apps function, is that is has a hard time reading text and sentences in the way that they are written.

- Can sometimes bunch them together, doesn't skip some onessary parts/symbols.

- Have a hard time reading text från PDF-files in the browser (they usually are wierd in format to begin with so it's tricky)

Very good. Russian read awesome. Online books are no longer a problem, and generally all the text on the pages. Very comfortably. The desired function at some points.
