Speech-in-speech recognition scores tend to be more variable than the speech-in-noise recognition scores, both within and across listeners. This variability could be due to listener factors, such as individual differences in audibility or susceptibility to informational masking. It could also be due to stimulus variability, with some speech-in-speech samples posing more of a challenge than others. The purpose of this experiment was to test two hypotheses: (1) that stimulus variability affects adults' word recognition in a two-talker speech masker and (2) that stimulus variability plays a smaller role in children's performance due to relatively greater contributions of listener factors.
