In a recent study, keywords were elicited in spontaneous speech samples from eight pairs of interlocutors who completed the “spot-the-difference” Diapix task in one of three acoustic environments: quiet, 2-talker babble, or 8-talker babble. In some conditions, talkers were in the same acoustic environment and in others they were in disparate environments. In all cases, the acoustic environments were presented over headphones in order to obtain clean recordings of the speech but maintain the influence of the environment on production. The current study investigated the perception of the keywords in each of the three acoustic environments at different signal-to-noise ratios, when they were presented in either the same or disparate adverse environment than ones in which they were elicited. Results from the current experiment will be discussed with regard to intelligibility obtained when words were presented in the same vs. different environments; the differences obtained in perception might indicate whether ...
