Embodiment Construction

[0065] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0066] The singing imitation method described in the first embodiment of the present invention is used to convert the voice of the source singer into the voice with the timbre of the target singer. The method includes a training phase and a conversion phase, where:

[0067] For the training phase, see figure 1 , including steps S101-S105:

[0068] S101, using the STRAIGHT model to calculate the fundamental frequency sequence value and the spectral envelope coefficient for the audio materials corresponding to the source singer and the target singer;

[0069] Adaptive Weighted Spectral Interpolation (STRAIGHT) is a high-quality speech synthesizer, which can effectively separate the speech sound source from the filter, decompose the sp...

Abstract

The invention provides a method for singing imitation. The method comprises the steps that corresponding audio materials of a source singer and a target singer are prepared; voice features of the source singer and voice features of the target singer are analyzed by using a STRAIGHT model; a joint GMM model of the source singer and the target singer is obtained through training by using a Gaussian mixture model; Gaussian transform functions based on inter-frame correlation are used in the tone conversion process; the tone of the source singer and the tone of the target singer are mixed in proportion; voice having the tone of the target singer is reconstructed by using the STRAIGHT model. The invention further provides a device for implementing the method. According to the method and device, the voice of the source singer can be converted into the voice having the tone of the target singer, converted tone quality is good, the tone is close to the tone of the target singer, and the tone features of the target singer can be added in proportion; especially, when the target singer is a music star, the self-confidence and interestingness of singing for the user at a digital audio and video place can be improved greatly, and meanwhile the level of the user for imitating the tone of the music star is improved.

Description

technical field [0001] The invention relates to a method for converting timbre, in particular to a method for singing imitation. Background technique [0002] With the popularity of smart terminals, people have higher and higher requirements for intelligent life services, and voice intelligent services have become an urgent need for people. [0003] In the existing singing compensation system, there is a technology for correcting the singer's pitch, so that the singer can still sing in the standard pitch when the singer is out of tune, but less involves the technology of converting the singer's timbre to imitate the singer's timbre . The intelligence of the karaoke system urgently needs a technology that allows users to imitate singers' singing through machine assistance, and the timbre is close to that of professional singers, thereby greatly improving the user's confidence and fun in singing, and improving the user's ability to imitate the singer's timbre.
