The default voice is unintelligible and the other voices are not much better. This is a joke of an app.

In Dutch it just uses the Microsoft TTS-voice (Frank), which is already build in in Firefox itself, rendering this extension completely useless. The UI adds nothing special, you can't even choose where you want it to start reading.

Voces robóticas ininteligibles

Horrible, garbled, unintelligible robotic voices. Way to much reverb, too fast and they all sound alike. Chrome's built in text to speech is a hundred times better and it is just a dull monotone, but at least you can understand it.

This used to work okay now it sounds so robotic and distorted it's unusable!! It speaks everything 2x as fast as before and you can't understand a single word it's saying! IT'S BROKEN! uninstalled

Irritable, terrible, insufferable... I cannot concentrate when the robot rapes my ear with its artificial, hacky voice. Whoever programed this extension needs a little water boarding.

Now being somewhat series... Firefox,, you are a tech company, right? act like one! We have AI that is indistinguishable from human voice almost. GET WITH IT! NO EXCUSES

Does not work at all. It crashes immediately after selecting the addon.

Hilariously bad. Literally sounds like a backyard full of dogs barking. Not a single word was discernible.

This add-on claims to have "offline" voices which are "never sent to the internet".

However if you block access to the servers it contacts using a firewall:

1) You can see tons of access sent to "support.readaloud.app" and "chart.googleapis.com"

2) The text to speech stops working entirely. It won't read at all and says "Phone not connected". You can't even use the example offline test voice in configurations panel.

How is this even remotely offline if it can't work when not connected to the internet and their servers in particular?
