Have quickly tested it with English, French and Italian (by selecting a bit of text in a Web page): smooth! Lovely voices and accents. :)

highlight the text, no matter what language, and it reads it for you!

not bad

Very happy that I have found the Add-on

非常棒！

Me encanta esta extensión, así puedo concentrarme mejor en leer (Muy útil para los que tienen déficit de atención)

I am dyslexic. I find the app very helpful and easy to use. I love the way it highlights the text as it reads it in its own little window with a good background colour!
