| Summary: | 碩士 === 國立中山大學 === 電機工程研究所 === 82 === This thesis describes an analysis and synthesis system of
Mandarin speech signal from frequency domain. From the KLT,
many speech frames can be segmented into several sub- words.
The KLT also can be used for signal compression and signal
reconstruction in the analysis part of this system. We can also
use the critical band concept in acoustics to reduce the
feature dimension in the frequence domain. The voiced/unvoiced
band system is replaced for voiced/unvoiced frame system in the
synthesis part of this system. It can effectively detect the
period of the fre- quency bands between the relation of
different signals from the periodic pulse and the source
signal. At last, the voiced bands and the unvoiced bands signal
portions are synthesized in the time domain and then added
gether to prodduce Mandarin speech. The synthesized speech is
quite distinguishable and it alsodeserves the tone of the
original speakers.
