I wish we could chose the voice

Very good *if* enabling a proper voice. Select "Edit" in front on "Voices" and select e.g. English => Google Translate English, then "Back to options", and (in Firefox) grant required browser permissions to access the voice.

By default, the voice sounds much like the regretted physicist S. Hawking (and the app becomes worth 1 star).

Four stars because it's not quite as natural-sounding (intonations etc..) as say Google Android Assistant on "read aloud" command, using their browser.

Its cool that it properly punctuates sentences instead of just reading words.

Great! if you want to read more related to education then go to Students Level and Hindi Folks

Its the best TTS addon out there. tested a lot of addons but this one is pretty good. how to use it for pdf files? it tries to upload pdf to read it. but reads epub files perfectly

Looks Good.

great tool. shortcuts dont work on mac os (no alt key). no way to edit shortcuts.

The add-on is great and overall it works very well. You can customize the speech speed and pitch, stop, and rewind it. That said, it does have an issue on some linux distributions where it crashes the pulseaudio driver (but not all). It's not clear why this happens, but when it does the driver has to be restarted and then the plugin doesn't work again until a reboot. It's a bit of a niche problem so I only took off one star for it. That said, I put in a bug report for it and have heard nothing back from the dev despite a patch being released after my bug report.

Top TTS reader imo. Amazon voices are now great. Couple problems I've encountered are inability to edit shortcuts (though there's a page for that) and no speed control on the fly. I would also appreciate text highlighting to be more precise. It's hard to find what you're looking for when the whole paragraph is highlighted.

软件本身的体验很棒，但是 在Chrome中，我需要翻墙才能使用语音朗读的功能，这让我感觉很麻烦。

Good Add-on. The voices sound good. I would like the option for the pop-up window to be a bit larger. It's still quite small when enlarging. Actually, it would be even better is the reading was directly on the page with more visual aids, for better readability.

Funcionalmente 5 estrellas.
Le pongo 4 solamente porque la voz no es de lo mas agradable.
