Abstract
This study investigated the extent to which children (ages 5–17) can take advantage of differences in fundamental frequency (F0) contour between target and masker speech to improve speech-in-speech recognition. A number of studies show that differences in F0 and F0 contour between talkers support better speech-in-speech recognition for adults, suggesting it is an important cue for recognizing speech in multitalker environments. However, children’s use of F0 contour differences during speech-in-speech recognition is less well understood. In the present study, sentence recognition was measured adaptively in a two-talker speech masker. Target and masker sentences were recorded with either normal, flat, or exaggerated F0 contours. Results revealed that children’s sentence recognition was impacted by differences in F0 contour depth in both target and masker speech, but the pattern of results differed between children and adults in some conditions. For children, the consistent nature of the flat F0 contour often had a greater impact on speech recognition thresholds (SRTs) than target/masker differences in F0 contour depth. Observed age effects did not appear to be due to limitations in children’s ability to use F0 contour differences in general but are likely related to the perceptual salience of the target contour relative to the masker.
