Speech recognition goes way beyond digital assistants. Plain old transcription is super useful, especially in terms of accessibility. I was voice coding for a while because of RSI and even as immature as the tech is, it saved my ass.
I tried a few. Caster and talon were the best. I’d recommend talon with dragon as it’s speech engine, but apparently talon has a new built in speech engine which people like, so maybe try that engine first to save money.
