摘要
Abstract
Speech recognition is one of the key technologies in human⁃machine speech communication. A speech recognition system and its voise processing program flow are introduced. The way that Mel frequency cepstrum parameters are used to extract features,and the measurement estimation algorithm based on hidden markov model(HMM)are elaborated. The strict testing results show that the system can meet the requirement of practicability. The speech recognition system realized Chinese characters voice input under the condition of resource limited in electrommunication equipments. This system has great practical significance.关键词
