Show moreThis chapter presents an experimental study of consecutive interpreting which investigates whether: (a) judged fluency can be predicted from computer-based quantitative prosodic measures including temporal and melodic measures. Ten raters judged six criteria of accuracy and fluency in two consecutive interpretations of the same recorded source speech, from Chinese ‘A’ into English ‘B’, by twelve trainee interpreters (seven undergraduates, five postgraduates). The recorded interpretations were examined with the speech analysis tool Praat. From a computerized count of the pauses thus detected, together with disfluencies identified by raters, twelve temporal measures of fluency were calculated. In addition, two melodic measures, i.e., pitch level and pitch range, were automatically generated. These two measures are often considered to be associated with speaking confidence and competence. Statistical analysis shows: (a) strong correlations between judged fluency and temporal variables of fluency; (b) no correlation between pitch range and judged fluency, but a moderate (negative) correlation between pitch level and judged fluency; and (c) the usefulness of effective speech rate (number of syllables, excluding disfluencies, divided by the total duration of speech production and pauses) as a predictor of judged fluency. Other important determinants of judged fluency were the number of filled pauses, articulation rate, and mean length of pause. The potential for developing automatic fluency assessment in consecutive interpreting is discussed, as are implications for informing the design of rubrics of fluency assessment and facilitating formativeassessment in interpreting education.

Show moreThe present study presents an experiment to investigate 1) whether judged fluency correlates with judged accuracy of consecutive interpreting performance; and 2) whether and how judged fluency can be predicted on the basis of acoustic measures such as automatically calculated temporal measures of speech quality. In the experiment, ten raters judged six major quality measures related to accuracy and fluency of the consecutive interpreting performance (in this study from Chinese into English) recorded from seven BA trainees and five MA trainees based on the same recorded source speech. Six consecutive interpretations per participants were recorded, two of which were analyzed acoustically by means of the speech analysis tool PRAAT. The pauses detected by PRAAT and the disfluencies transcribed and labeled manually were automatically counted by the text analysis computer program of AWK, based on which 12 acoustic measures of fluency were calculated. The results show that 1) there is a strong positive correlation between judged accuracy and judged fluency in consecutive interpreting; 2) there are strong correlations between judged fluency and objective acoustic measures of fluency in consecutive interpreting; and 3) effective speech rate appears to be the best predictor of judged fluency in consecutive interpreting. The other important determinants of judged interpreting fluency are number of filled pauses, articulation rate, and mean length of pause. The results have practical implications for both developing an automatic assessment tool of fluency facilitating consecutive interpreting testing as well as for consecutive interpreting pedagogy.
