Top-down repair of interrupted speech can be influenced by bottom-up acoustic cues such as voice pitch (F0). This study aims to investigate the role of the dynamic information of pitch, i.e., F0 contours, in top-down repair of speech. Intelligibility of sentences interrupted with silence or noise was measured in five F0 contour conditions (inverted, flat, original, exaggerated with a factor of 1.5 and 1.75). The main hypothesis was that manipulating F0 contours would impair linking successive segments of interrupted speech and thus negatively affect top-down repair. Intelligibility of interrupted speech was impaired only by misleading dynamic information (inverted F0 contours). The top-down repair of interrupted speech was not affected by any F0 contours manipulation. (C) 2017 Acoustical Society of America
