Speaker verification without background speaker models
Speaker verification concerns the problem of verifying whether a given utterance has been pronounced by a claimed authorized speaker. This problem is important because an accurate speaker verification system can be applied to many security applications. In this paper, we present a new algorithm for speaker verification called OSCILLO. By applying tolerance interval analysis in statistics, OSCIL...
متن کاملSpeaker Verification Using Speaker-Specific Prompts
Intraand inter-speaker information, which include acoustical, speaker style, speech rate and temporal variation, despite their critical importance for the verification of claims, still have not been captured effectively. As a result of such modeling deficiency, existing speaker verification systems generally test claimed utterances with interfacing procedures that are common to all speakers. In...
متن کاملAcoustic-labial Speaker Verification
This paper describes a multimodal approach for speaker ver-iication. The system consists of two classiers, one using visual features and the other using acoustic features. A lip tracker is used to extract visual information from the speaking face which provides shape and intensity features. We describe an approach for normalizing and mapping dierent modalities onto a common conndence interval. ...
متن کاملBiologically inspired speaker verification
Speaker verification is an active research problem that has been addressed using a variety of different classification techniques. However, in general, methods inspired by the human auditory system tend to show better verification performance than other methods. In this thesis three biologically inspired speaker verification algorithms are presented. The first is a vowel-dependent speaker verif...
متن کاملSpeaker verification improvemen distortion
In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into account real situations where the training material has been recorded in a controlled situation but the testing signals present some mismatch with the input signal level (saturations)...
