Electroglottographic parameters in evaluation of voice quality. Acoustic analyses from a singer and aeroelastic modelling

Popis výsledku v původním jazyce

Relations between electroglottographic (EGG) parameters and voice qualities were studied. Data were obtained from one male singer phonating on four pitches in three loudness levels (soft, medium, loud), and in three phonation types (breathy, normal and pressed), which represent varying degrees of adduction. Acoustic signal, EGG and oral pressure were recorded. For comparison, contact area was studied in relation to varying fundamental frequency, sound pressure level and pre-phonatory glottal half-width,using aeroelastic model of voice production. In the case of the singer the degree of firmness of phonation was perceptually analyzed from sound samples by three speech trainers. In modelling data, the prephonatory glottal half-width was used to simulatethe degree of firmness. Pearson correlations between different parameters were calculated. Closed quotient (CQ) correlated best with the degree of perceived firmness in the human data. Modelling data, however, did not show significant co
