When actors and voice artists speak within the context of a dramatic presentation, they may use disfluencies to make their speech sound more authentically spontaneous. However, there has been little study of whether these simulated disfluencies match patterns produced during truly spontaneous (that is, unscripted and unprepared) speech. The aim of this project was to evaluate this in a mini corpus of film and television dramas, as well as in elicitation from professional voice actors. A small corpus of 10 films and television shows was assembled, comprising a total of 122 filled pauses. The relatively small number means that conclusions are tentative, but the use of filled pauses seemed to fit typical patterns of use. They were more frequent at major than minor discourse boundaries, and uh was more frequent than um. An exception was that they did not necessarily precede words of low contextual probability, as has been previously shown in spontaneous speech. Two professional voice actors were hired to re-produce two different texts in three manners: scripted speech, scripted speech with simulated disfluency, and original spontaneous paraphrase. Two voice actors made recordings and results showed that the simulated disfluency was quite different from their actual disfluency.
