【Abstract】 Speaker recognition is a sort of biological recognition technology by which a person can be identified by his sound.By using VQ and HMM technology on VC platform,the authors realized speaker recognition.By Baum-Welch algorithm that was improved with genetic algorithm,they proved that the recognition efficiency of the HMM algorithm-based speaker recognition was improved.更多还原
