Inhalt:
This work investigates babblings during crises in Italian persons undergoing Court-of-Law examinations. The analysis was conducted on an audio/textual corpus that extends the one provided by the DIKE project. We found that most of crises (more than 80%) were characterized by babblings. Thus, we tried to characterize babblings looking at low-level acoustic features – such as speech pauses, word durations, intensity/pitch contours, intensity/pitch mean values – and found interesting results. Then we analyzed words in babblings, highlighting semantic roles and grammatical typologies; and again we found interesting clues. We conclude that in stressful setting, as Courtof- Law examinations, during crises, babblings exhibit a precise behavior, in terms of both acoustic and grammatical features.
