  • Abstract
    The authors propose nonlinear quantisation of the spectral shape in sub-band coding. This computationally simple method is shown to yield substantial improvement in speech quality. The performance improvement obtained is computed for 8-band and 16-band coding schemes operating at 16 kbit/s.
