Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 to Figure 7 , the present invention is a voice-controlled intelligent toy car system based on TMS320VC5509A. After recognizing the sound signal through a non-specific human voice recognition chip, the corresponding control command is obtained through DSP processor 2 chip processing, so as to realize the running state of the car, temperature collection, music, etc. Playing, information display and other functions, the system of the present invention adopts the combination of DSP processor 2 and voice recognition module 1 to realize the smart car driving state and its corresponding turn signal light control, vehicle speed control, vehicle music playback, vehicle interior temperature acquisition and other modules. Re...

Abstract

The invention relates to the field of voice signal processing and intelligent control, in particular to a voice control intelligent toy car system based on TMS320VC5509A. The difference is as follows:the system comprises a voice recognition module which is an LD3320 chip, template keywords are preset in the LD3320 chip, the voice recognition module performs spectral analysis on input voice signals through an ARS voice recognition technology to extract parameters representing voice features in the input voice signals, then the parameters are compared with the template keywords, and the keywordwith the highest matching degree is found out to serve as a voice recognition signal to be output; the system also comprises a DSP processor, which is a DSP chip of TMS320VC5509A, the input end of the DSP processor is connected to the voice recognition module, and the DSP processor is used for converting the voice recognition signal output by the voice recognition module into a control signal andsending the control signal to a control object of a toy car so as to execute a corresponding action command. The system overcomes the defects of a man-machine interaction plate of an existing toy car, achieves voice control, and is high in performance and low in power consumption.

Description

technical field [0001] The invention relates to the field of automatic voice recognition technology ASR and intelligent control, in particular to a voice-controlled intelligent toy car system based on TMS320VC5509A. Background technique [0002] In recent years, with the improvement of my country's economic level, the per capita disposable income is gradually increasing. Most of the new generation of "post-80s" parents are highly educated and pay more attention to children's early education and entertainment. Therefore, they have a high willingness to consume toys. This will provide impetus for the consumption growth of toys; due to the rapid development of speech recognition technology, more and more children's toys have begun to introduce this technology, injecting new vitality into the children's toy market; [0003] Speech recognition is to allow the machine to convert speech signals into corresponding text or commands through the process of recognition and understanding....
