    • Abstract
  • The decomposition algorithm of the characteristic waveform interpolation (WI) speech coding is investigated.A novel WI speech coding algorithm based on pitch synchronization is proposed.In the new speech coding algorithm,the quantization of the characteristic waveform is the variable dimension vector quantization (VDVQ).The decoding speech of 2.4 kb/s shows it can deliver decoded speech with high communication quality
