This is a userscript to add a TTS "speech" button to Blaseball games. Click the button to have it read the game log and send updates to the browser TTS. Now you can listen along!

You will need some kind of userscript extension to add this into. I have tested with Tampermonkey on Chrome (Windows). It is finicky, but works for me :)
