Abstract: Provided are a method and an apparatus for periodically measuring speech quality in a voice over Internet protocol (VoIP) terminal while a VoIP call between VoIP terminals is in progress. The method comprises: receiving summary information regarding traffic sent from an opposite VoIP terminal; and evaluating speech quality by comparing the summary information with actually received information regarding the traffic sent from the opposite VoIP. Accordingly, each VoIP terminal can precisely evaluate the speech quality periodically and send the evaluation result to each other.
