Embodiment
[0054] Firstly, the acoustic features of the speech that are important to distinguish the acoustic elements of the target contrast speech are expanded. For each group of speech to be learned, it is necessary to determine the specific physical parameters of natural sound processing according to the distinguishing elements of the acoustic features of the two speeches.
[0055] After the natural recording is obtained by the speech acquisition module 4 in the corpus production unit 1, it is sent to the speech processing module 5, and the spectral features in the sound are amplified in three different degrees by the MATLAB-based sound processing sub-module 14, respectively 300%, 208 %, 144%, and then make four grades of learning corpus together with the original voice. For example, in English speech / r-l / pair, the three parameters are F3 separation frequency, F3 bandwidth, and F3 transition time. During the synthesis process, the formant frequency difference of / r−l / is amplified ...
