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.

Great

Recently, the extension has been acting up on Firefox, constantly throwing the `NS_ERROR_DOM_MEDIA_METADATA_ERR` error. There's nothing wrong with the base64 audio being received, I verified that. Somehow it's triggering an old bug in Firefox I think, mentioned in this StackOverflow post: httpsstackoverflowcom/questions/44200990/html5-audio-player-in-firefox-is-not-working

EDIT: I found the issue. It was me. I diff'd my prefsjs file with a default one. Found out a sus config I don't remember changing. media.ffvpx.enabled was set to false. Setting it to true again fixed it. I am not sure why, maybe the decoding logic lives there..?

perfect, thank you

It is one of the best ad ons I have ever used. It really makes those long articles quite easy to get through and it even has a way to speed up each article.
A definite time saver

Very easy to use. The free voices are HQ and pronounce everything just fine. Really helps me focus as I have trouble reading on my own sometimes.

Read Aloud is an excellent tool for using with school and work. Thank you.
