Research on Information Technology with Voiceprint Authentication Algorithm and its Implementation on Mobile Terminal

Abstract:

Mobile internet and its application is hot information technology. The study integrates and improves some speech processing algorithms to make them suitable for the mobile terminal environment and to realize user identity authentication. It uses one body's unique voiceprint information which has the characteristics of convenient, concise, efficient and safe. By studying pre-emphasis, hamming window and other speech signal pretreatment, the voiceprint feature extraction technique of Mel cepstrum parameters, pattern matching algorithm DTW, a algorithm scheme is established. The scheme has been implemented and verified. It is suitable for treating small amount of words voice authentication.
