| Abstract(in English) | The formant information on wide-band speech signals is expected to apply for speech synthesis and recognition techniques. However, it is difficult to estimate formants in the high-frequency region of the wide-band speech signals. In this paper, we adopt a filter model of formant/anti-formant on the s domain as a vocal tract transfer function and show possibility of high-accuracy estimation of formant/anti-formant from wide-band speech signals. The estimation algorithm is including pre-emphasis processing, pitch synchronous and solver of minimization problems on γ domain with convex function. More over we shows availability of this algorithm for formant/anti-formant estimation using real vowels. |
