On the other hand, checkboxes "chime", "time" and "date" are checked that means that Your Voice Reminders will tell you time, date and play chime at startup. How it tells the time and date depends on the settings in Saying Time, Date and Greeting preferences.

To record the greeting itself just click the button Record Message and record it. Modern laptops usually have built in microphones and desktops the sockets to plug them in. Your Voice Reminder will automatically enable the microphone and sets the recording level before the recording. After the recording it will automatically subtract the noise and trim the silence at the ends. Your part of the job is just to say "Good morning!" or other appropriate greeting.
