Have messages read out loud in Messages on Mac
Messages can speak the text in a transcript, the Messages window, or a profile window.
Ask Siri. Say something like:
“Read my messages”
“What was my last text?”
In the Messages app on your Mac, select a conversation or select text to be read.
To search for contacts and content in conversations, click in the Search field in the top-left corner and enter what you’re looking for. Or, choose from the suggested contacts, links, photos, and more.
If you’re restricted to sending and receiving messages with only certain people, an hourglass icon appears next to those people you can’t send messages to.
Choose Edit > Speech > Start Speaking.
To make the speaking stop, choose Edit > Speech > Stop Speaking.
To change the computer’s speaking voice, choose Apple menu > System Preferences, click Accessibility, then click Spoken Content. Click the Help button for more information.
