my suggestion is to use piper voices ... its better for compreension...

First time user of the Read Aloud text to speech reader -- I am very impressed. I used the app to read a technical article and found the accuracy excellent. I also found the voice tone and intonation made for an exceptionally good listener experience. This is a great app and congratulations to its developers. Thank you!

An excellent way to get good TTS voices for Firefox. For the flatpak version I had to use flatseal to add .local/share/piper to the Persistent -> Files section to allow it to save the Piper voices.

Very excellent plugin. I wonder if it would be possible to add hover icons to Android Firefox, AND it would make it easier to use!

Add-On works really well. You can adjust the pitch/speed of the voice and even use different voices. Get it.
