Application of voice recognition system oriented to wireless sensor network in National Defense Education

Abstract

Combining with the in-depth study of speech signal processing technology, the sound can be matched to a unique speech recognition target, and the direction, type and content of the sound can be accurately located. In this paper, a self-organizing sensor node is designed and applied, which can monitor and collect various environmental information. Cover and report to interested users after processing. Due to its advantages such as strong flexibility, high reliability, convenient expansion, and good economy, wireless sensor networks are beyond the reach of other technologies in the new era. They are used in the fields of military, industrial manufacturing and control, environmental protection, and sanitation supervision. With great advantages, wireless sensing technology has been widely used. Countries all over the world that value university defense research have relatively complete defense systems, mechanisms, and legal systems. Israel’s training institutions are networked, training content is systematized, training guarantees are militarized, and the long-term effects of national defense training and defense force building are improved. In the United States, we must conscientiously establish a legal guarantee system for national defense training and use, continue to establish facilities for reserve officers, and continue to adhere to the “key disciplines” of local schools and universities to lay the foundation for national defense. Based on the acoustic signal processing technology, this paper improves the wireless sensor network and applies it to national defense training.
