| Abstract | A speech analysis apparatus according to the invention, comprising a transforming section for receiving a spec trum envelope, for transforming the spectrum envelope such magnitude data thereof becomes suitable, and for generating a transformed spectrum envelope, an inte grator for receiving the transformed spectrum envelope output from the transforming section, for integrating the input spectrum envelope with respect to a predeter mined variable, and for outputting an integrated spec trum envelope, and a projection circuit for receiving the transformed spectrum envelope from the transform circuit and the integrated spectrum envelope from the integrator, and for projecting the spectrum envelope with respect to the integrated data. Therefore, the anal ysis result inherent to the phoneme can be obtained regardless of vocal tract lengths. The spectrum enve lope to be projected can be integrated by the integrator, along the frequency axis or the mel axis. The analysis apparatus further includes a spectrum envelope-extrac tor for obtaining the spectrum envelope, by using cep strum analysis and smoothing the resultant spectrum envelope. A spectrum envelope in the transition from a consonant to a vowel can be obtained. |
