Abstract :
This paper proposes a fuzzy approach to the hidden Markov model (HMM). This method celled the fuzzy HMM for speech and speaker recognition as an application of fuzzy expectation maximizing algorithm in HMM. The fuzzy HMM algorithm is regarded as an application of the fuzzy expectation-maximization (EM) algorithm to the Baum-Welch algorithm in the HMM. The Texas Instruments p4 used speech and speaker recognition experiments and show better results for fuzzy HMMs compared with conventional HMMs. Equation and how estimation of discrete and continuous HMM parameters on based this two algorithm is explained and performance of two speech recognition method for one hundred is surveyed. This paper show better results for the fuzzy HMM, compared with the conventional HMM.
