Orthogonal wavelet division multiplexing for wideband time-varying channels
Block transmission of multi-scale orthogonal wavelet division multiplexing (OWDM) is proposed for signaling over wideband linear time-varying channels (LTV). Such channels are bes...

Glottal inverse filtering using stabilised weighted linear prediction
This paper presents and evaluates an inverse filtering technique of the speech signal which is based on the Stabilized Weighted Linear Prediction (SWLP) of speech [1]. SWLP empha...

HMM-based speech synthesiser using the LF-model of the glottal source
A major factor which causes a deterioration in speech quality in HMM-based speech synthesis is the use of a simple delta pulse signal to generate the excitation of voiced speech. ...
