A method of self-adaptive switching between male and female voices
An adaptive, male-female technology, applied in speech analysis, speech recognition, instruments, etc., can solve the problems of not being able to monitor the gender of the speaker in real time, and not being able to automatically change the voice change target, so as to achieve accurate dynamic judgment, reduce misjudgment rate, and judge accurate effect

Embodiment
[0038] Such as figure 1 As shown, the method for adaptively implementing male and female voice switching in this embodiment includes the following steps:
[0039] (1) Training process:
[0040] (1-1) Collect phonetic databases: mainly extract 10 groups of male and female voice databases based on words from the electronic Chinese dictionary real-person pronunciation database, including 5 groups for boys and 5 groups for girls. Each database contains the pronunciation and pronunciation of 3,893 commonly used words. ;
[0041] (1-2) Perform averaging energy preprocessing on the voice data in the voice database;
[0042] Firstly, the data of the start point and end point of the voice is intercepted, and the average energy of the entire voice is first counted. In order to simplify the calculation, the present invention takes the average value of the absolute value of each voice data as its average energy The first voice signal value is greater than That is the voice start point, the las...

The invention discloses a method for achieving self-adaptive switching of a male voice and a female voice. The method comprises the steps that when training is conducted, voice data of a voice database are sectioned, voice data of a voice frequency database are extracted, the dynamic and static Meyer cepstrum characteristics of the voice data are extracted, and then the voice data are transmitted to a depth limitation Bohr machine network for voice gender study. When a user uses the voice frequency database, voice signals are collected, the voice signals are processed according to the steps the same as the voice data of the voice database and are transmitted to the depth limitation Bohr machine network and the voice gender is judged; according to the result of the judgment of the voice gender, the inflexion target is set, the time dynamic programming SOLAFS algorithm is used for regulating the duration of the voice signals and sampling the duration of the voice signals again according to the inflexion target, and finally the effect of switching the male voice and female voice automatically is achieved. The method for achieving the self-adaptive switching method of the male voice and the female voice switching method can distinguish the gender in real time and set the inflexion target in a self-adaptive mode and then carry out the real-time inflexion processing, parameters do not need to be set manually when the method is used every time, and the dynamic judgment of the voice is accurate.
Description
Technical field [0001] The invention relates to the field of machine learning and audio processing, in particular to a method for adaptively realizing male and female voice switching. Background technique [0002] The mutual conversion of male and female voices is achieved by changing the pitch and timbre of the voice signal. The traditional method is to use voice signal processing methods. It is an important theoretical research direction in the field of voice signal processing, and male and female voice switching can be used in confidential communication and entertainment. Communication and other fields have very good practical application value. At present, there are many methods designed to switch between male and female voices. For example, the current patent CN03137014.4 provides a voice change method, which achieves the effect of voice change by manually setting the voice change target and changing the signal length. Patent CN200410062337.1 uses frequency spectrum shiftin...
