Pseudo Multi Parallel Branch HMM for Speaker Verification

Part of the Advances in Intelligent and Soft Computing book series (AINSC, volume 57)

Summary

This paper describes an approach, called Pseudo Multi Parallel Branch (P-MPB) Model, for coping with performance degradation typically observed over (short and medium) time and trials in Text Dependent Speaker Verification’s task. It is based on the use of a fused HMM model having a multi parallel branch topology where each branch consists of an HMM referring to a specific frame’s length representation of the speaker. The approach shows reasonable ER’s reduction from the baseline system.
