Les trajectoires formantiques respectant les lois de la physique contribuent-elles à une meilleure perception de la parole ?
Résumé
Physical properties of speech articulators contribute to shape articulatory and formant trajectories. This study aims at evaluating the role of this shaping in speech perception. We conducted perception tests of synthetic stimuli generated with speech production models accounting for different degrees of physical complexity. Our results do not provide any support to the hypothesis that the degree of physical realism in the models influences the perception of naturalness. However for degraded speech (silent center speech), significant differences are observed.
