The analyses were done on second language Dutch and English speech materials that were collected for fluency evaluative purposes. The results of this study showed that intervals of vocalic articulation in filled pauses and lengthened vowels have a similar duration. The results for the standard deviation of F0-3 frequencies in Dutch disfluencies showed similarities for filled pauses and lengthened vowels uttered by females and males. Whereas the results from the English materials showed less uniformity for the effects of the disfluency types and sexes.Show less
