Your Mac has a very productive ability to speak the time every 15, 30 or 60 minutes using a built-in speech synthesizer.
This flow will help you if you have difficulty seeing the system clock or forget to check the time while working, enabling this feature can help you stay on task and avoid forgetting about your commitments.
As of now, it speaks the time every hour round the clock. Will fix this in coming updates.
