  • Publication number: 20160329059
    Abstract: The present application discloses a pulse encoding method for use by a voice encoder. An initial number of coding bits is determined according to number of pulses in an input signal. An index value is calculated according to information of the pulses in the input signal. The index value is compared with an adjustment threshold value. If the index value is smaller than the adjustment threshold value, the index value is encoded using a reduced number of encoding bits. If the index value is not smaller than the adjustment threshold value, the index value plus an offset value is encoded using the initial number of encoding bits. The reduced number of encoding bits is smaller than the initial number of encoding bits, and the offset value is greater than or equal to the adjustment threshold value.

  • Publication number: 20150179187
    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.
