VOICE COMMUNICATION APPARATUS AND VOICE QUALITY ESTIMATION METHOD

摘要

PROBLEM TO BE SOLVED: To inexpensively estimate voice quality without the need for a large-scale system configuration in the case of making a speech by transmitting / receiving a voice packet to / from a speech opposite apparatus being a speech opposite party via a network.

SOLUTION: A voice communication apparatus for making a speech by transmitting / receiving a voice packet to / from the speech opposite apparatus being the speech opposite party via the network includes: a detection means for detecting a state of the network located between the voice communication apparatus and the speech opposite apparatus; an estimation means for estimating the voice quality on the basis of the network state detected by the detection means; and an output means for outputting information denoting the voice quality estimated by the estimation means; and also a recording means for recording a transmission timing every time an echo request packet is transmitted and recording a reception timing every time an echo response packet is received, and the detection means detects the state of the network on the basis of the recording contents.
