Multi-channel speaker verification based on total variability modelling
In this work we address the speaker verification task in domestic environments, monitored by multiple distributed microphones. In particular, we focus on the problem of mismatch in the propagation channel between the enrolment stage, which occurs at a fixed position, and the test phase which could happen in any location of a multi-room apartment. Building upon the Total Variability framework an...
متن کاملInter-Speaker Variability: Speaker Normalisation and Quantitative Estimation of Articulatory Invariants in Speech Production for French
Speech production can be analysed in terms of universal articulatory-acoustic phonemic units shared between speakers. However, morphological differences between speakers and idiosyncratic articulatory strategies lead to large inter-speaker articulatory variability. Relationships between strategy and morphology have already been pinpointed in the literature. This study aims thus at generalising ...
متن کاملArticulatory speaker normalisation based on MRI-data using three-way linear decomposition methods
The aim of this study was to characterise, to model and to compare the different lingual articulatory strategies of a group of speakers. Individual principal component analysis (PCA) and multi-linear decomposition methods have been applied to different representations of the tongue contour extracted from magnetic resonance images (MRI). The corpus consisted of seven speakers articulating 63 Fre...
متن کاملR-norm: improving inter-speaker variability modelling at the score level via regression score normalisation
This paper presents a new method of score post-processing which utilises previously hidden relationships among client models and test probes that are found within the scores produced by an automatic speaker recognition system. We suggest the name r-Norm (for Regression Normalisation) for the method, which can be viewed as both a score normalisation process and as a novel and improved modelling ...
متن کاملBiomechanical Tongue Models: An Approach to Studying Inter-Speaker Variability
Speakers of a given language vary with respect to their acoustics, articulation, and motor commands. This variation is driven by a variety of influences, such as emotional states, communicative interaction, and individual properties of the vocal tract. In this work we focus on the latter. First, we build speaker-specific biomechanical tongue models. Second, we discuss the impact of the relative...
