Problems solved by technology

[0002] In the use environment of home appliances, there are often scenarios with multiple speakers. In this scenario, the speech recognition system will receive many pseudo-instructions, and the recognition system will process the speech of each speaker as an instruction source, which is not practical. The speaker who wants to control the home appliance interacts, which seriously affects the recognition rate and interactive experience of the speech recognition system

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0049]In a family environment, there are often multi-person conversation scenarios. In this environment, if the voice recognition system is working, it needs to process various voices. Due to the presence of voice input all the time, it is difficult for the voice recognition system to enter the dormant state and remain in the voice recognition state to identify voice signals. However, most of the voices recognized at this time are irrelevant interference v...

Abstract

The invention relates to a voice recognition method and method based on sound source localization and an intelligent household appliance. The voice recognition method comprises the following steps of: when the intelligent household appliance enters a voice recognition state, acquiring a voice signal, and controlling a timer to start timing; if the voice signal is acquired when the time recorded by the timer is less than or equal to a preset time, performing location according to the voice signal, and determining position information a sound source corresponding to the voice signal; and determining whether to control the intelligent household appliance to perform recognition of the voice signal or not according to the position information and prestored voice recognition area information, thereby removing interferential voice signals, effectively improving recognition rate of the voice recognition system, and promoting interactive experience of a user.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method and system based on sound source localization, and smart home appliances. Background technique [0002] In the use environment of home appliances, there are often scenarios with multiple speakers. In this scenario, the speech recognition system will receive many pseudo-instructions, and the recognition system will process the speech of each speaker as an instruction source, which is not practical. The speaker who wants to control the home appliance interacts, which seriously affects the recognition rate and interactive experience of the speech recognition system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a voice recognition method and system based on sound source localization, and intelligent home appliances for the deficiencies of the prior art. [0004] The technical solut...
