in that case, you should be able to add voices to speech-dispatcher. Sadly I don't have a list of docs on hand, but I'm sure you can find it and make it work

the built-in TTS actually just uses the TTS voices provided by your system, so if you're on Windows, I believe it's possible to add other voices

Yeah, looks like it on my end as well. Thanks for letting us know. For now, if you click Additional downloads, you can scroll down and manually select the dmg file

and you don't want to fork over the money for a subscription or lifetime activation to get enough buttons for your setup. (2/2)
