I found that when I happen to talk over top of someone during a voice call, the voice of the other person will breakup (drop syllables) for a moment afterwards. I found that if I put the speaker on and are listening to hold music or something and have some background noise, it will cause it to breakup. I am not sure if it is my phone or the network or what. It drives me crazy as I am always asking people to repeat themselves. I am in good coverage.
