Disfluencies as Extra-Propositional Indicators of Cognitive Processing

چکیده
We explore filled pause usage in spontaneous medical narration. Expert physicians viewed images of dermatological conditions and provided a description while working toward a diagnosis. The narratives were analyzed for differences in filled pauses used by attending (experienced) and resident (in-training) physicians and by male and female physicians. Attending physicians described more and used more filled pauses than residents. No difference was found by speaker gender. Acoustic speech features were examined for two types of filled pauses: nasal (e.g. um) and non-nasal (e.g. uh). Nasal filled pauses were more often followed by longer silent pauses. Scores capturing diagnostic correctness and diagnostic thoroughness for each narrative were compared against filled pauses. The number of filled and silent pauses trends upward as correctness scores increase, indicating a tentative relationship between filled pause usage and expertise. Also, we report on a computational model for predicting types of filled pause.

Disfluencies, language comprehension, and Tree Adjoining Grammars
Disfluencies include editing terms such as uh and um as well as repeats and revisions. Little is known about how disfluencies are processed, and there has been next to no research focused on the way that disfluencies affect structure-building operations during comprehension. We review major findings from both computational linguistics and psycholinguistics, and then we summarize the results of ...
متن کاملDisfluencies and human language comprehension.
Spoken language contains disfluencies, which include editing terms such as uh and um as well as repeats and corrections. In less than ten years the question of how disfluencies are handled by the human sentence comprehension system has gone from virtually ignored to a topic of major interest in computational linguistics and psycholinguistics. We discuss relevant empirical findings and describe ...
متن کاملDisfluencies in Switchboard
Disfluencies (“um,” repeats, self-repairs) are prevalent in spontaneous speech, and are relevant to both human speech communication and speech processing by machine. Although disfluencies have commonly been viewed as ‘noisy’ events, results from a large descriptive study indicate that disfluencies show regularities in a number of dimensions [9]. This paper reports selected results on Switchboar...
متن کاملA Corpus of Spontaneous Speech in Lectures: The KIT Lecture Corpus for Spoken Language Processing and Translation
With the increasing number of applications handling spontaneous speech, the needs to process spoken languages become stronger. Speech disfluency is one of the most challenging tasks to deal with in automatic speech processing. As most applications are trained with well-formed, written texts, many issues arise when processing spontaneous speech due to its distinctive characteristics. Therefore, ...
متن کاملEffects of concurrent cognitive processing on the fluency of word repetition: comparison between persons who do and do not stutter.
UNLABELLED This study investigated how silent reading and word memorization may affect the fluency of concurrently repeated words. The words silently read or memorized were phonologically similar or dissimilar to the words of the repetition task. Fourteen adults who stutter and 16 who do not participated in the experiment. The two groups were matched for age, education, sex, forward and backwar...
