Tested in French, and it's Google voice, it's very good. On my Android device, though, I've installed better voices, paying, it would be cool to be able to use Android voices with this extension, but I don't know if it would be possible one day. EDIT: I let a very good review 2 years ago, I don't know if the addon has gone less good, or if it's because I use it on a different machine, but the voice, in English or French are so so so robotic, that I can barely understand what it says.

It works well but it gets stuck on things. For example if its italics then it reads it over and over. Same thin with numbers it will reread it over and over.

5 stars for ease of use. 2 stars for A.I. voice. No choices for voice.

La voz española es un poco molesta y se siente como si fuese una máquina, no es muy natural. Por favor, incluyan una voz latina.

不稳定，第一次装上就有声音。过了几天就不能朗读网页了。莫名其妙，也没有什么可以设置的选项
