Household Acoustic Control Switch

Abstract With the rapid development of economy, intelligent residential area is becoming more and more popular。 However, in every family have given priority to with manual switch。 Therefore, it is necessary to design a safe and simple and convenient voice activated switch, make people smart home life more comfortable, more intimate, more convenient。 In this paper the STC11l08XE microcontroller, combined with the speech recognition processor ld3320, security, energy saving, simple structure household acoustic control switch is realized。 Firstly, this paper summarizes the research status of voice control switch, and puts forward the design scheme of the system based on the analysis of the existing research data。 Voice input, power circuit, speech recognition and intelligent control of the four parts of the system circuit。 The function of the system mainly includes the voice acquisition and the voice recognition, and then the function of the control system is realized

After the test, the system is small and exquisite, easy to use, energy saving and environmental protection, the speech recognition accuracy, can be conveniently realizes the control of the switch。 To achieve the expected goal。

This paper has 15 figures, 3 tables, 9 references。
