At some point in my Nexus 4 history the phone began alerting me to messages that have been waiting for a while - apparently either voice or text- in a spoken aloud message by an authoritative male voice. This has woken me up more than once and startled me or others more than once. I have no idea where to find or turn off this feature. I thought it might have originated with our current cell provider whom we switched to a year ago but my husband on his Nexus 5 doesn't have it. I would like to say Goodbye aloud to Mr. "Excuse me, you have a message waiting." He isn't even smart enough to tell me what form of message is waiting and I keep wasting time checking for voice mail.
