Problems solved by technology

[0003] There are mainly two existing VAD detection methods: one is the VAD detection method based on energy and zero-crossing rate. In the case of the detection accuracy is very low
Another detection method is based on the VAD detection method of deep learning. This method has higher accuracy, but the calculation load is relatively large, and the performance requirements of the equipment are relatively high.

Abstract

According to the embodiment, the invention provides a voice signal endpoint detection method, a detection device, detection equipment and a storage medium. The method comprises the following steps: acquiring a first audio signal, wherein the first audio signal comprises a voice signal; detecting a starting point of the voice signal from the first audio signal via either a first voice activity detection (VAD) algorithm based on energy and zero-crossing rate or a second VAD algorithm based on deep learning; and after detecting the starting point of the voice signal, detecting an ending point ofthe voice signal via the other one of the first VAD algorithm and the second VAD algorithm. Therefore, the accuracy of detecting voice signal endpoints is guaranteed, and meanwhile, a computing amountis reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of voice detection, and in particular, to a voice signal endpoint detection method, device, device, and storage medium. Background technique [0002] Voice Activity Detection (VAD for short), also known as voice endpoint detection, is usually used in voice interaction scenarios to detect user voices, so as to perform corresponding control or voice interaction operations based on user voices. [0003] There are mainly two existing VAD detection methods: one is the VAD detection method based on energy and zero-crossing rate. In this case, the detection accuracy is very low. Another detection method is the VAD detection method based on deep learning. This method has higher accuracy, but has a large amount of calculation and requires higher performance of the device. Contents of the invention [0004] Embodiments of the present application provide a voice signal endpoint detection...
