Abstract

The present invention discloses a speech data processing method and device, a computer device and a storage medium. The method comprises the steps of: obtaining original speech data; employing a VAD (Voice Activity Detection) algorithm to perform framing and segmentation processing for the original speech data to obtain at least two frames of speech data to be tested; employing an ASR (Automatic Speech Recognition) feature extraction algorithm to perform feature extraction of each frame of speech data to be tested to obtain speech features of a filter to be tested; employing a trained ASR-LSTM(Long-Short Term Memory) speech recognition model to perform recognition for the speech features of the filter to be tested to obtain a recognition probability value; and if the recognition probability value is larger than a preset probability value, taking the speech data to be tested as target speech data. The method can effectively remove the interference of the noise and the mute so as to improve the accuracy of the model recognition.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice data processing method, device, computer equipment and storage medium. Background technique [0002] Voice Activity Detection (VAD), also known as voice endpoint detection or voice boundary detection, is to identify and eliminate long periods of silence from the sound signal stream, so as to save voice channels without reducing service quality. The role of resources. [0003] At present, when training or recognizing speech recognition models, it is necessary to obtain relatively pure speech data for model training, but the current speech data is often mixed with noise or silence, resulting in the use of speech data mixed with noise for training. The accuracy rate of the speech recognition model is low, which is not conducive to the popularization and application of the speech recognition model. Contents of the invention [0004] Based on this, it is necessar...
