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.

Edit: They fixed it within the week. Review changed from 3 to 5 stars.

Would usually give it higher stars but it's stopped working on Firefox mobile since the last update (Jan 2024). I have reported and it's been a couple days so I'm reviewing to raise awareness.

Great plugin which also reads PDFs. Google login to use premium voices works fine for me. Make sure to select one of the Google Translate voices somewhere at the bottom of the selection box.
