Abstract

The invention provides a speech data processing method, a speech data processing apparatus, an electronic device and a readable storage medium and belongs to the data processing technical field. According to the method, the initial frequency domain parameter of speech data is obtained; a target frequency domain parameter corresponding to a preset target MIDI (Musical instrument Digital Interface)audio is obtained; and the initial frequency domain parameter is modified according to the target frequency domain parameter, so that tune modified speech data can be obtained. With the method adopted, speech in the speech data can have the frequency domain parameter of the target MIDI audio, so that the tune modified speech data can have the pitch feature of the target MIDI audio, tune modification operation on the speech data can be realized; tune modification can be performed on the speech data under a condition that tunes and sound lengths in the speech data are not changed; the phases ofthe tune modified speech data are continuous, noises can be avoided; and mechanical noises can be avoided, so that a tune modification effect is better. The method can be applied to the correction ofmedian pitch in songs, or conversion from voices to singing, etc., and has a bright application prospect in the sound processing field.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a voice data processing method, device, electronic equipment and readable storage medium. Background technique [0002] Voice change is to change the speaker's tone through a certain algorithm without changing the speech rate of the audio file, including the translation of the tone and the conversion of the voice to a specific tone. The existing modulation processing will have phase discontinuity and noise problems. Contents of the invention [0003] In view of this, the present invention provides a voice data processing method, device, electronic equipment, and readable storage medium, which can solve the above problems and realize voice phase continuity after modulation. [0004] The technical scheme provided by the invention is as follows: [0005] A voice data processing method, comprising: [0006] Acquiring voice data and target MIDI audio, the voice da...
