Improving short utterance based i-vector speaker recognition using source and utterance-duration normalization techniques
A significant amount of speech is typically required for speaker verification system development and evaluation, especially in the presence of large intersession variability. This paper introduces a source and utterance-duration normalized linear discriminant analysis (SUN-LDA) approaches to compensate session variability in short-utterance i-vector speaker verification systems. Two variations ...
متن کاملImproving Short Utterance PLDA Speaker Verification using SUV Modelling and Utterance Partitioning Approach
This paper analyses the short utterance probabilistic linear discriminant analysis (PLDA) speaker verification with utterance partitioning and short utterance variance (SUV) modelling approaches. Experimental studies have found that instead of using single long-utterance as enrolment data, if long enrolledutterance is partitioned into multiple short utterances and average of short utterance i-v...

متن کاملShort Utterance PLDA Speaker Verification using SN-WLDA and Variance Modelling Techniques
This paper proposes a combination of source-normalized weighted linear discriminant analysis (SN-WLDA) and short utterance variance (SUV) PLDA modelling to improve the short utterance PLDA speaker verification. As short-length utterance i-vectors vary with the speaker, session variations and phonetic content of the utterance (utterance variation), a combined approach of SN-WLDA projection and S...
متن کاملCompensation of utterance length for speaker verification
The effect of utterance length on the estimation of the likelihood of a speaker has previously seen a brief treatment in past works. In many speaker recognition evaluations, the utterances were typically configured to have a relatively consistent length. This paper investigates the effect of varying enrollment and test utterance lengths on the score distributions and consequently their effect o...
