Here’s the way to set it up:
Open System Preferences by clicking the Apple icon in the upper left corner of your screen.Select “System Preferences” from the menu that appears.Click “Date & Time” in “System Preferences” in MacOS Catalina or earlier. Click “Dock & Menu Bar” on MacOS 11 Big Sur or later.If you are running Catalina or earlier, click the “Clock” tab in the “Date & Time” preferences.In Big Sur or later, scroll down the “Dock & Menu Bar” sidebar and click “Clock” button.
When you have “Clock” preferences, place a checkmark next to “Announce Time.”Using the drop-down menu, you can customize it if you want your Mac to announce the hour, half-hour, or quarter-hour time.Example, if you select “On the quarter-hour,” you will hear the announcements at 2:00 p.m., 2:15 p.m., 2:30 p.m., and 2:45 p.m.The voice is going to say, “It’s two o’clock” or “It’s two forty-five.”
Press the “Customize Voice” button to change the voice that speaks the time out loud.You can choose a male or female voice on the screen, and you can also adjust the speech rate.As long as you have the volume of your system turned up, you’ll hear the time you’ve spoken at the intervals you set.
