A number of studies have shown that the intelligibility of speech spoken deliberately clearly, referred to as âclear speechâ or CLR speech, is higher than that of speech spoken during typical communication, referred to as âconversational speechâ or CNV speech. Significant changes in the acoustic features of CLR speech, as compared to those of CNV speech, have been found in previous studies. However, little is known about the relationship between speech intelligibility and the individual sets of acoustic features that are typical in CLR speech. Our long-term goal is to better understand and model those features that contribute to speech intelligibility for different groups of normal-hearing listeners. One objective of this thesis is to identify acoustic features that contribute to the increased intelligibility of CLR speech over CNV speech, which we refer to as ârelevant featuresâ for normal-hearing listeners. Our hypothesis is that some acoustic features are more relevant to increased
