Method, apparatus, and equipment for processing voice data, and readable storage medium

Abstract

The invention discloses a method for processing voice data. The method comprises: a frequency spectrogram of a target voice file is obtained and the obtained frequency spectrogram is displayed; a target frequency range selected by a user in the frequency spectrogram is received and corresponding target voice data are determined based on the target frequency range; and the target voice data are extracted, the extracted frequency spectrogram processed, and the frequency spectrogram are played. According to the method, the user is able to select a specific determined frequency range automaticallyaccording to the frequency spectrogram of the target voice file; and because the voice data are selected by the user based on the frequency spectrogram, the selected voice data have the optimized quality; no denoiding process is needed for the voice data, so that the original voice audio quality is not affected and thus the voice audio file is played clearly; and the voice data processing efficiency is improved because of the low selected voice volume. Correspondingly, the invention also discloses an apparatus and equipment for processing voice data, and a readable storage medium that have the same technical effects.

Description

technical field [0001] The present invention relates to the technical field of audio processing, and more specifically, relates to a method, device, equipment and readable storage medium for processing voice data. Background technique [0002] With the continuous development and integration of computer technology and audio processing technology, voiceprint identification technology has been widely used in judicial identification, providing a good technical guarantee for judicial identification. [0003] At present, for the voice spectrogram of the voice file to be authenticated, the existing voiceprint identification system can select the voice spectrogram of a specific area in time. However, since the frequency range of each voice signal is specific and constant, and the existing system cannot select a specific frequency range, it is necessary to select all frequency ranges of the voice data, and when the frequency range of the voice data covers the high-frequency region ,...
