Design and Construction of Intelligent Voice Control System

With the development of speech recognition technology, there are wide applications of intelligent voice around the world. In the paper, we propose an intelligent voice control system which can realize the functions of voice activity detection, speech recognition, speaker authentication, instruction analysis, and automatic answer. A new voice activity detection (VAD) algorithm and backtracking algorithm are proposed to improve system performance. Then, we test our system in our own silumation corpus, we create the system evaluation indexes and the text result is satisfactory.
