Embodiment 1

[0061] In order to solve the technical problem that voice detection cannot be performed in the prior art, an embodiment of the present disclosure provides a voice detection method. Such as figure 1 As shown, the speech detection method mainly includes the following steps S11 to S14.

[0062] Step S11: Determine the first signal energy of the original signal.

[0063] Specifically, the original signal may be collected by the voice collection device in the incoming wave direction of the original signal. There may be one or more voice collection devices. When there is one voice collection device, the signal collected by the voice collection device in the incoming wave direction of the original signal is directly used as the original signal. When there are multiple voice collection devices, the multiple signals collected by the multiple voice collection devices in the incoming wave direction of the original signal are calculated as an average signal, and the average signal is us...

Abstract

The invention discloses a voice detection method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: determining first signal energy of an original signal; determining second signal energy according to a plurality of first signals acquired by a plurality of voice acquisition devices in the incoming wave direction of the original signal; when the difference between the first signal energy and the second signal energy is greater than a preset energy threshold, acquiring a plurality of second signals acquired by the plurality of voice acquisition devices in a direction adjacent to the incoming wave direction; and determining whether a voice signal exists in the original signal or not according to the relevancy of the plurality of first signals and the plurality of second signals. According to the embodiment of the invention, when the difference between the first signal energy and the second signal energy is greater than the preset energy threshold, whether the voice signal exists in the original signal is determined according to the relevancy between the plurality of first signals and the plurality of second signals, so that the detection accuracy of the voice signal can be further improved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular to a voice detection method, device and computer-readable storage medium. Background technique [0002] With the development of science and technology, the beamforming technology in the microphone array is used to pick up or suppress speech components in specific directions, which is applied to many speech detection scenarios. In many existing noise reduction algorithms, it is necessary to detect whether there is a target sound source at the current moment. [0003] For example, in the noise reduction algorithm, it is necessary to judge whether there is a target sound source at the current moment. If there is no target sound source, it will be treated as noise, and the adaptive filter needs to be updated; otherwise, it will not be updated. For another example, in the noise estimation algorithm, when the noise power spectrum is counted, it is also necessary ...
