Change Siri settings for accessibility on Mac
On your Mac, use Siri settings for accessibility to type your requests to Siri instead of speaking them. This feature can be useful if speech is difficult or you don’t want others to hear your Siri requests.
To change these settings, choose Apple menu 
in the sidebar, then click Siri on the right. (You may need to scroll down.)
