Embodiment Construction

[0110] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0111] figure 1 It is a flowchart of a wake-up voice determination method provided by an embodiment of the present disclosure, the method is applied to a computer device, see figure 1 , the method includes the following steps.

[0112] 101. Perform feature extraction on the speech to be processed to obtain a first speech feature of the speech to be processed.

[0113] 102. Classify the first speech feature to obtain a classification result.

[0114] 103. In response to the classification result indicating that the speech to be processed is the wake-up speech, acquire a second speech feature based on the classification result.

[0115] 104. Perform interpolation processing on the second speech feature to obtain a third speech fea...

Abstract

The invention provides a wake-up voice determination method and device, equipment and a medium, and belongs to the technical field of audio processing. According to the technical scheme provided by the embodiment of the invention, after whether a to-be-processed voice is a wake-up voice or not is preliminarily determined through primary classification, secondary classification verification is carried out under the condition that the to-be-processed voice is determined to be the wake-up voice, false wake-up can be avoided through two times of classification, and the wake-up accuracy is improved. And during secondary verification, feature extraction is performed based on the classification result of the primary classification, and the target length is obtained in an interpolation mode, so that the length of the voice features of feature extraction is not limited, the situation that the speech features include mute segments or wake-up words are incomplete can be effectively avoided, and the wake-up accuracy and success rate are further improved.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular to a method, device, device and medium for determining a wake-up voice. Background technique [0002] In recent years, with the continuous development of audio processing technology, intelligent voice interaction systems such as smart speakers and vehicle-mounted voice interaction systems have become popular. In order to reduce user operations, a voice wake-up function is provided. By recognizing the collected voice, it is determined Whether it is a wake-up voice, and then the voice wake-up of the device can be realized. [0003] In related technologies, the wake-up voice determination method usually includes: extracting features of the voice to be processed, obtaining fixed-length voice features, and inputting them into a convolutional neural network (Convolutional Neural Networks, CNN) network for classification. [0004] The length of the wake-up word read ...
