Not sure if it quite fits here, but I wanted to shout out a TTS browser extension Read Aloud.

https://github.com/ken107/read-aloud

In addition to Piper voices which run locally in a browser and are quite good on their own, they also added Supertonic voices recently, which sound even better, are also running locally/synthesized in-browser and are even faster and lighter.

I'm usually too lazy to read long articles, so this extension is pretty convenient, I can just play and listen to it while I do something else.
