  • GitHub repo saka-key

    A keyboard interface to the web

    Project mention: Helix: a post-modern text editor | | 2021-06-01

    Check demo animation on Saka Key's readme:

    Project mention: What is your favorite FOSS speech synthesizer? What is your current speech synthesis setup? | | 2021-06-18

It is a browser extension for Chrome/Firefox that can use both FOSS synthesizers and external proprietary ones. You can expand voices by installing more local voices. You can for free use their "Basic" voices or pay a small fee for some of their Premium voices (if you pay for premium, as I did for 1 USD, you will get free additional characters every month. I am currently sitting with more characters than I started with). You can alternatively give API keys for Google Cloud, AWS, or IBM. If you want more quality voices.

Some of the other plugins are pretty decent, too,
