Embodiment Construction
[0051] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0052] The speech conversion method under the asymmetric corpus condition based on adaptive algorithm, comprises the following steps:
[0053] 1) Use the STRAIGHT model for feature extraction on the sentences of all speakers, and extract Mel-cepstral coefficients (Mel-cepstrum coefficients, MCC) and pitch frequency (F0) respectively.
[0054] 2) The spectral feature MCC training extracted from the pre-prepared third-party reference speaker's training sentence generates a background model that sati...
