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.
