                    abstract = {Current HMM-based low bit rate speech coding systems work with
  phonetic vocoders. Pitch contour coding (on frame or phoneme level)
  is usually fairly orthogonal to other speech coding parameters. We
  make an assumption in our work that the speech signal contains
  supra-segmental cues. Hence, we present encoding of the pitch on the
  syllable level, used in the framework of a recognition/synthesis
  speech coder with phonetic vocoder. The results imply that high
  accuracy pitch contour reconstruction with negligible speech quality
  degradation is possible. The proposed pitch encoding technique
  operates on 30 - 35 bits per second.},
