Non-specific voice recognition intelligent switch system based on single-chip microcomputer

Abstract

The invention provides a non-specific voice recognition intelligent switch system based on a single-chip microcomputer. The non-specific voice recognition intelligent switch system comprises a voice recognition module, a main control module and a relay switch module. The voice recognition module is used for performing spectral analysis and extracting voice features according to received voice, andmatching the extracted voice features with keywords in a keyword list to obtain a voice recognition result; the main control module sends a control command to the relay switch module according to thereceived voice recognition result; and the relay switch module performs switching action according to the received command. According to the invention, accurate identification of a household appliance control command is realized, and complex manual training is avoided; through the mutual cooperation of the two commands, the influence of other sound sources is reduced, the recognition rate is improved, and the household appliance control precision is greatly improved.

Description

technical field [0001] The present disclosure relates to the technical field of speech recognition, in particular to a non-specific speech recognition intelligent switch system based on a single-chip microcomputer. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Problems solved by technology

[0004] The inventors of the present disclosure found that the traditional home appliance control methods, including switch buttons and infrared remote control, mainly have the following problems: there is a need for people to directly touch, there is a potential safety hazard of strong electricity leakage; the control is inconvenient; unsafe, Sometimes it is not safe to connect wires privately for the convenience of switching; there are few control locations, and at most two places can be controlled; the control distance is short and cannot pass through walls; when there are too many remote control models, the signals are easy to confuse
