Automatic Evaluation of Voice Quality Using Text-Based Laryngograph Measurements and Prosodic Analysis
Original language description
In this study, text-based, computer-aided prosodic analysis and measurements of connected speech were combined in order to model perceptual evaluation of the German Roughness-Breathiness-Hoarseness (RBH) scheme. 58 connected speech samples (43 women and15 men; 48.7 +- 17.8 years) containing the German version of the text "The North Wind and the Sun" were evaluated perceptually by 19 speech and voice therapy students according to the RBH scale. For the human-machine correlation, Support Vector Regression with measurements of the vocal fold cycle irregularities (CFx) and the closed phases of vocal fold vibration (CQx) of the Laryngograph and 33 features from a prosodic analysis module were used to model the listeners' ratings. The best human-machine results for roughness were obtained from a combination of six prosodic features and CFx (? = 0.71, ? = 0.57). These correlations were approximately the same as the interrater agreement among human raters (? = 0.65, ? = 0.61). CQx was one of
