Formant frequency is one of important parameters for speech signal. This paper presents a new formant detection algorithm based on cepstrum. Firstly, the traditional speech formant method is discussed. To overcome the weakness of traditional method, an extraction method based on formant enhancement is described. Then, the first-order derivative of phase-frequency characteristics has better frequency resolution than logarithmic amplitude-frequency characteristics, so the first-order derivative of phase-frequency characteristics based on formant enhancement is proposed. Finally, the experimental results show that formants parameters can be extract more precisely.

And Function

Disagreement exists on the degree to which rate of speech and segmental duration affect the formant frequency characteristics of vowels. Post hoe analysis of the vowel characteristics of words uttered by women in conversational speech with both adult and child addressees indicates that there is no simple relationship between the length of vowels and the degree to which their formant frequency characteristics resemble those seen in citation forms of speech. In the ease of women addressing children, it was possible for content and function words to share formant frequency characteristics that maximally differentiated their embedded vowels, despite the relatively shorter duration of function word vowels. Implications for the elicitation of "clear speech" are discussed.

Physiological Alterations

Previous literature indicates that a difference may exist between formant frequencies (F1 and F2) of children, young adult, and elderly speakers. The purpose of this study was to compare F1 and F2 of 3 young, 6 young adult, and 3 elderly female speakers for the /i/, /æ/, /u/, and /a/ vowels. Analysis indicates a trend towards vowel reduction across the life span. These findings support previous research regarding age-associated acoustic changes as well as support for the possible anatomical and physiological alterations which may influence such changes.
