It's probably announcing when the network coverage switches from one coverage to another (wifi to LTE, 4G to 3G, etc).
Look in your notification settings, or under your network options to see if there is a setting for a notification when changing networks.
We want you to enjoy your phone and not have it make announcements you don't want, DAVWAG84. I remember some of the phones back in the day making this announcement on incoming calls, and that's what I thought of when I read your post. Here's another suggestion to look at if SuzyQ's suggestion doesn't do the trick. In settings, click on Sound. Click Sound effects. If "Sound when roaming" is on, turn it off. Keep us posted on what happens.

Someone from your call center fixed it. The key was a total Reset. From settings. It worked!! The issue was the phone would randomly announce "Verizon Wireless" in a female voice. This happened 10 to 20 times per day and did not relate to anything I was doing with the phone. Mostly the phone was in my pocket when it happened. But thanks. Your colleague fixed it
