Embodiment approach

[0062] In the first method, the step of converting the voice signal control instruction into a control signal recognizable by the home smart device further includes:

[0063] Establish a communication connection between the audio signal detection server and the cloud server;

[0064] The audio signal detection server compares the voice signal control command with the data information stored in the cloud server, and recognizes the voice information contained in the voice signal control command;

[0065] Obtain the device type of the home smart device;

[0066] According to the recognized voice information and the device type, the voice signal control instruction is converted into a control signal recognizable by the household smart device.

[0067] In the second type, the step of converting the voice signal control instruction into a control signal recognizable by the home smart device further includes:

[0068] The audio signal detection server compares the voice signal cont...

Abstract

The present invention provides a smart home control method based on audio signal detection. The method comprises the steps of: establishing connection between at least one home smart device and an audio signal detection server, wherein the audio signal detection server receives audio signals emitted to the home smart device by users and identifies whether the audio signals is an audio signal control command or not; if yes, converting the audio signal control command to control signals which can be identified by the home smart device, and transmitting the control signals to the home smart device, wherein the home smart device receives control signals and executes corresponding control operation. The method provided by the invention detects whether the received audio signals are audio information or not and identifies whether the received audio signals are a control command or not so as to improve the audio identification accuracy and provide convenience for users' usage.

Description

technical field [0001] The invention relates to the technical field of smart home control, in particular to a smart home control method based on audio signal detection. Background technique [0002] Audio signal processing is a complex cross-cutting technical field. In recent years, audio processing technology has been widely used. [0003] The basis of audio processing is speech detection, and the purpose of audio detection is to detect whether a speech signal exists. [0004] In the prior art, in the detection of voice information, the recognition accuracy of the voice information is not high due to the existence of environmental noise. At present, the process of audio detection is usually: acquiring each audio signal, extracting characteristic parameters from each audio signal for semantic analysis, and then knowing whether the audio signal is speech according to the result of semantic analysis. [0005] However, semantic analysis requires a lot of calculations and tem...
