Definitions

  • a voice encoder/decoder is used to compress voice signals so as to reduce the transmission bandwidth over a communications channel. By reducing the bandwidth per call, it becomes possible to place more calls over the same channel.
  • vocoders There exists a class of vocoders known as code excited linear prediction (CELP) vocoders. In these vocoders, the speech is modeled by a series of filters. The parameters to these filters can be transmitted with much fewer bits than the original speech. It is also necessary to transmit the input (or excitation) to these filters in order to reconstruct the original speech. Because it would require too much bandwidth to transmit the excitation directly, a crude approximation is made by replacing the excitation by a few non-zero pulses.
  • CELP code excited linear prediction
