Abstract

The embodiment of the disclosure provides a hybrid sampling rate acoustic model training method and device and electronic equipment, and belongs to the technical field of data processing. The method comprises the steps: acquiring a first sound data object comprising a first sampling rate and a second sound data object comprising a second sampling rate; respectively carrying out feature extractionon the first sound data object and the second sound data object; when the feature number of the first dimension feature is different from that of the second dimension feature, performing dimension alignment operation on the first sound data object and the second sound data object to obtain a third dimension feature of the first sound data object and a fourth dimension feature of the second sound data object; and training a hybrid sampling rate acoustic model based on the third dimension feature and the fourth dimension feature. Through the processing scheme, the training efficiency of the acoustic model can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a mixed sampling rate acoustic model training method, device and electronic equipment. Background technique [0002] Speech processing (Speech processing), also known as voice signal processing, human voice processing, its purpose is to make the desired signal, further do voice recognition, apply to the mobile phone interface and even ordinary life, so that people and computers can communicate. [0003] In the process of speech processing, the audio-like sound signal received by a microphone or other devices can be used to process the data through an analog-to-digital conversion device, and finally output through a digital-to-analog conversion device. Therefore, the processing is for digital signals, and the speech signal is a discrete time signal. The signal processing flow is as follows: Collect and sample signals: use a microphone or various radio devices...
