Abstract

In order to realize a speech coding at low bit rates, a pitch information is useful parameter. In case of extracting an average pitch information from continuous speech, the several pitch errors appear in a fram which consonant and vowel are coexistent: in the boundary between adjoining frames and beginning or ending of a sentence. In this paper, I propose an Individual Pitch(IP) extraction method using residual signals of the FIR-STREAK digital filter in order to restrict the pitch extraction errors. This method is based on not averaging pitch intervals in order to accommodate the changes in each pitch interval. As a result, in case of IP extraction method using FIR-STREAK digital filter, I can't find the pitch errors in a frame which consonant and vowel are coexistent: in the boundary between adjoining frames and beginning or ending of a sentence. This method has the capability of being applied to many fields, such as speech coding, speech analysis, speech synthesis and speech recognition.
