Figure 14From: Classification of speech under stress based on modeling of the vocal folds and vocal tractAverage classification results of four cost functions: C F 1 ‒ F 2 , C rms , C I-S , and C E-F . The results for varied VF and fixed VT are the classification rate when the stiffness parameters are estimated with fixed VTL and cross-sectional area. Varied VF and varied VT denote that the parameters for stiffness and cross-sectional area are estimated by fitting the two-mass model to real speech.Back to article page
