Good Performers Know Their Audience Identification and Characterization of Pitch Contours in Infant- and Foreigner-Directed Speech... 

A pre-existing data-set of infant-, foreigner- and adult-directed speech samples in WAV format formed the basis of the data-set (Knoll and Uther, 2(X)4). Pitch contours were randomly selected from these groups and then modified to a standardized format that could be used for the DAISY, EA and qualitative conditions. The extracted pitch contours comprised the specific target words sheep , shark and shoe, which were chosen because they had been found to be prosodicaUy highlighted in IDS and FDS in a previous study (KnoU and Uther, 2004). A total of 167 pitch contours (IDS = 60, ADS = 53, FDS = 54) were extracted from these words.
