Abstract

The invention discloses a voice directing method and system based on intelligent equipment. The method comprises that after that the intelligent equipment is started, a voice signal is obtained in real time; when the voice signal is detected by the intelligent equipment, a present foreground image of the intelligent equipment is obtained, and a candidate direction of a sound source is obtained according to the present foreground image; and according to the candidate direction of a sound source, the intelligent equipment carries out calculation via a positioning algorithm, and then determines a sound source direction of the voice signal according to a calculation result. According to the invention, the candidate direction of the voice signal obtained in advance is calculated by combining image collection, the candidate direction is checked via the algorithm, the optimal sound source direction is obtained, the computing complexity is reduced, and the positioning efficiency of the voice signal is improved.

Description

technical field [0001] The invention relates to the technical field of voice processing, in particular to a voice orientation method and system based on an intelligent device. Background technique [0002] On smart devices, especially home smart devices, voice interaction is an important human-computer interaction mode. At present, there are many methods for the processing of microphone arrays, such as linear constraint minimum variance criterion, maximum likelihood criterion and maximum signal-to-noise ratio criterion, multi-signal classification (MUSIC), rotation invariant technique signal parameter estimation (ESPRIT) and other methods, related Algorithms are generally more complex. [0003] The existing microphone array signal processing method generally adopts the DOA method, and the DOA method is DirectionOf Arrival. The wave-of-arrival method is used to estimate the direction of arrival from the target transmitter by using one's own radar. The estimation of DOA meth...
