Hidden Markov Model for Speech Recognition Using Modified Forward-Backward Re-estimation Algorithm


Balwant A. Sonkamble

There are various kinds of practical implementation issues for the HMM. The use of scaling factor is the main issue in HMM implementation. The scaling factor is used for obtaining smoothened probabilities. The proposed technique called Modified Forward-Backward Re-estimation algorithm used to recognize speech patterns. The proposed algorithm has shown very good recognition accuracy as compared to the conventional Forward-Backward Re-estimation algorithm.

Keywords: Forward-Backward Algorithm; Speech Recognition, Parameter Estimation, Viterbi Algorithm, Baum-Welch Algorithm.
