Biometrical Speaker Description From Vocal Cord Parameterization

The parameterization of vocal cord dynamics may be useful in different fields of voice processing, as in speech synthesis, voice pathology detection, or speaker identification, among others. A technique to determine biomechanical cord parameters is presented to produce estimates of mass, stiffness and losses from the body and cover structures of the vocal cords. Results from a database of normophonic subjects are in good agreement with values used in cord modelling. This technique provides biometrical descriptors of speakers with use in different fields of application
