Abstract:This paper intreduces a method which uses complex cepstrum to restore un- voiced speech. First, the characteristics of the unvoiced speech is analyzed; then, the fundamental frequency is added to the complex cepstrum to restore it to the normal speech. We have processed vowel a] and actual speech segments. The restorations worked effecitvely.
Keywords:Complex cepstrum  Unvoiced speech  Fundamental frequency
