In my language (Czech), it's like listening to a robot. Try the Edge browser, it has the reader already installed and it's perfect.

Every time I start it, it wants me to grant additional permissions. Additional? I gave it the permissions it needed when I ran it the first time so why do I have to give it additional permissions every day I run it? I want it to be given all the permissions it needs to run and make that permanent. Instead, you have to go through a tedious rigmerole of opening a webpage, scrolling down and clicking on a speak button, then tick a box saying you are not a robot EVERY TIME you use it! No! I won't do that.

I've noticed an issue with the way the Google Translate Bengali voice feature pronounces numerical values in English. Specifically, when the Bengali voice reads out English phrases containing numbers, the pronunciation of those numerical values is inaccurate.

For example, when the Bengali voice reads '24 hours', it pronounces it as 'chabbish (২৪) hours', where 'chabbish' is the direct Bengali pronunciation of the number '24', rather than the proper English pronunciation.

This problem seems to occur consistently across all numerical values when using the Google Translate Bengali voice. I was hoping you could provide guidance on how this numerical pronunciation accuracy could be improved within the Bengali voice feature. Having the Bengali voice deliver the correct English pronunciations for numbers would greatly help me.

Constantly asking to change permissions on Android. It became so annoying I had to remove it altogether.

It is a cool idea and helps a lot with my dyslexia. But it works properly less than half of the time.
1. Detecting the text correctly, especially on websites where text is separated by other content or when there are multiple columns.
2. Often the reading out does not stop when click pause or stop, I have to close all Firefox windows to make the reading out stop.

Piper's voices are really good. I really appreciate the automatic language selection.

The voice is good, but the controls don't do jack. The pause button does absolutely nothing ever, and the second time I tried the add on the highlighted text didn't match what was being read (no idea where in the document it was reading from) and this time I had to close the browser entirely to make it stop reading.

Solid add-on, but the fact that you need to have an entire tab open in order to use the new piper.ttstool voices makes the add-on much less convenient

1.68 update is leaving a residue static sound whenever there is text loaded in the extension. This is distracting and making the pause feature unusable for me.

Edit: I tried out older versions and retried the new one and the problem went away. No idea what was causing it. I encountered another bug however with the new "Piper" feature, the extension was not able to load the manager page where you install the voices. It worked on Brave though (I use LibreWolf)

Edit2: Static sound problem came back. I decided to revert back and stay in version 1.66 No longer experience the issue on that version.

Adding the piper voices is a game changer!! Thank you Dev.
Initially, I was pretty unhappy with the robotic voices and decided to read the reviews and found the same complaints. Then I saw that there was an update a week ago and, lo and behold, you can now add custom voices from piper that sound so much more human. It's a night and day difference. Makes this so much more worth it now. Even though it's still in the experimental phase, it works just fine for me.
I urge everyone to try it out in settings.
