Invention Idea: Speeding up Speach on the Cell Phone

It seems that cell phones generally cut out when they lose information due to poor signal strength or congestion. One idea here is that they could "catch up" by playing the audio slightly faster for periods of time. Of course, to prevent the sound from sounding strange to the human ear, it should not change the pitch of the sound. It may still sound natural if played at 10-20% faster than the original recording, and allow resynchronization of the time.
