Multiple recent studies have shown that speaker recognition performance using frame-based cepstral features is improved by adding higher-level information, including prosodic and lexical features. This paper explores the important question of finding a good kernel for a system that models syllable-based prosodic features using support vector machines (SVMs). The system has been the best performing...
<para> We present a new modeling approach for speaker recognition that uses the maximum-likelihood linear regression (MLLR) adaptation transforms employed by a speech recognition system as features for support vector machine (SVM) speaker models. This approach is attractive because, unlike standard frame-based cepstral speaker recognition models, it normalizes for the choice of spoken words...
