The design of the intelligent voice recognition system based on Labview

摘要

The recognition of speech sounds test system based on virtual instrument was designed successfully. For years, virtual instrument has become a huge active communication platform for user, and covered the multiple industries and fields of applications, becoming the data acquisition and instrument control the best choice. Based on the Labview 8.5 software platform, combined with PC sound card, microphones and other hardware acquisition of speech signal, the speech signal is filtered. Through the Hamming window, and power spectrum, the recognition of speech signal is realized. After the actual test and application, software operation is stable and reliable, with certain practicability and value of popularization and application.
