Voice Recognition Technology For Wireless Sensor Networks Research

As a new-style information acquisition system, wireless sensor network has the extremely widespread application prospect, may apply in the military, the environment, the health, the family and in other commercial domains. According to the present world military development trend, the wireless sensor network detection system has widely been used in the new generation of combat systems based information. Our research is mainly about sound identification of the low altitude, super-low altitude targets, with the background of wireless sensor network detection system. After analyzed the relative merits of software and hardware plan, we propose to use the hardware plan to carry on the sound recognition for this system. This article has made the summary of the circuit of sound detection and the speech chip plan to identify the sound as well as the questions appeared to triturating, and carried on the appraisal to this detection system. Based on the requirement of next step of micro miniaturization in this detection system as well as the existence shortcoming of speech chip plan, this article also has offered the improvement program to use the electric circuit with the DSP chip to identify the sound. We also research the sound recognition algorithm and bring forward to use the speech recognition algorithm to carry on the sound recognition which has been proved. We also has designed the hardware electric circuit of sound recognition processing and produced the system software design .These can provide the reference for further research.
