So Decky-Dication is a really cool plugin that lets you use voice typing in game mode. The github is here, but unfortunately they were never able to get the plugin small enough for it to be in the Decky store, and the project has since been abandoned.
Luckily, the plugin still works really well. You can build it yourself from the github, or if you’re trusting enough you can download an already built .zip file here.
Once you have the plugin file, unzip it on your deck, and move it to the homebrew/plugins folder. That folder is usually write protected, so you may need to move it using a terminal command (ie if you extracted the folder on the desktop, the command would be sudo mv ~/Desktop/decky-dication ~/homebrew/plugins. Then switch back to game mode and it should be in your plugin list.
Once the plugin is installed, you press steam+b+L2 to start speech to text, and then steam+b+r2 to disable it.
I actually haven’t used anything that makes use of the Deck microphones yet, do they work well for this?
The mics work well, but the speech to text can be hit or miss sometimes. You have to talk more clearly than you would when using your phone’s speech to text
