Abstract: A voice quality monitoring method and apparatus are provided, which solves a difficult problem of how to perform proper voice quality monitoring on a relatively long audio signal by using relatively low costs. The method includes capturing one or more voice signal segments from an input signal; performing voice segment segmentation on each voice signal segment to obtain one or more voice segments; and performing a voice quality evaluation on the voice segment to obtain a quality evaluation result according to the voice quality evaluation. Because the segmented voice segment includes only a voice signal and is shorter than the input signal, proper voice quality monitoring can be performed on a relatively long audio signal by using relatively low costs, thereby obtaining a more accurate voice quality evaluation result.

Abstract: In a pulse encoding and decoding method and a pulse codec, more than two tracks are jointly encoded, so that free codebook space in the situation of single track encoding can be combined during joint encoding to become code bits that may be saved. Furthermore, a pulse that is on each track and required to be encoded is combined according to positions, and the number of positions having pulses, distribution of the positions that have pulses on the track, and the number of pulses on each position that has a pulse are encoded separately, so as to avoid separate encoding performed on multiple pulses of a same position, thereby further saving code bits.
