For voice packets, the marker bits indicates the beginning of a talkspurt. Beginning of talkspurts are good opportunities to adjust the playout delay at the receiver to compensate for differences between the sender and receiver clock rates as well as changes in the NETWORK delay jitter. Packets during a talkspurt need to played out continuously, while listeners generally are not sensitive to SLIGHT variations in the durations of a pause.

The marker bit is a HINT; the beginning of a talkspurt can also be computed by COMPARING the difference in timestamps and sequence numbers between two packets, assuming the timestamp clock RATE is known.
