Our main assumptions for disfluency events are: (1) Repetition-like disfluency events exhibit a common underlying structure property in the frequency domain, (2) filled pauses exhibit specific acoustic correlates with a steady frequency signature (Gabrea and O'Shaughnessy, 2000), (3) these filled pauses have usually adjacent unfilled pauses/silences (Daly, 1994).
the extraction of these two tracks from continuous speech can be decomposed in several engineering tasks (see Figure 1).
