Two new hybrid companding delta modulators for speech encoding are presented here. These modulators differ from the Hybrid Companding Delta Modulator (HCDM) proposed by Un et al in that the two new encoders employ Song Voice Adaptation as the basis of the instantaneous compandor, rather than Constant Factor adaptation. A detailed analysis of the performance, both objective and subjective, of these hybrid codecs has been carried out. Results show that overall the two codecs developed as part of this project are better than the HCDM codec. In addition the new codecs offer simpler implementation in digital hardware than the HCDM. A Computer Aided Test (CAT) system has been developed to simplify the design and test processes for speech codecs. 2014-09-22T07:51:12Z 2014-09-22T07:51:12Z 1985 Master Thesis Masters MSc http://hdl.handle.net/11427/7587 eng application/pdf Department of Electrical Engineering Faculty of Engineering and the Built Environment University of Cape Town |
