Speaker Identification in the Shouted Environment Using Suprasegmental Hidden Markov Models
In this paper, Suprasegmental Hidden Markov Models (SPHMMs) have been used to enhance the recognition performance of text-dependent speaker identification in the shouted environment. Our speech database consists of two databases: our collected database and the Speech Under Simulated and Actual Stress (SUSAS) database. Our results show that SPHMMs significantly enhance speaker identification performance compared to Second-Order Circular Hidden Markov Models (CHMM2s) in the shouted environment. Using our collected database, speaker identification performance in this environment is 68 CHMM2s and SPHMMs respectively. Using the SUSAS database, speaker identification performance in the same environment is 71 CHMM2s and SPHMMs respectively.
