Similar to Tap to Alexa, Communication Without Speech displays a transcription of any messages left on your Alexa device by your contacts or family members, and it allows you to send messages to them by typing on your Echo Show screen. Turn it on under Settings > Accessibility > Communication Without Speech.
You can also access your contacts on screen via the three-dot vertical ellipsis menu that appears on the home screen. If you don't like the typing—which is awkward as can be on an Echo Show—there's a microphone icon front and center so you can say something to be transcribed.
Naughty words get censored on screen by the Echo Show (but you can always see the original curse-laden messages in the mobile Alexa app on your phone).
