Onepotential linkage variable is coarticulation. Two experiments were conducted toinvestigate the role of coarticulation in speech-on-speech recognition.Experiment 1 results indicated a significant main effect of coarticulation in thetarget speech, where coarticulation did not benefit the listener. It was unclear,however, how differences in local signal-to-noise ratio (SNR) across keywordsaffected these results. In Experiment 2, local SNR was controlled for acrosskeyword position. Results indicated no effect of coarticulation for the targetspeech regardless of local SNR. However, a significant main effect of maskertype was observed, with listeners benefiting from the presence of a SSNcompared to a two-talker masker. Data suggest that local intensity level plays arole in speech recognition, however the importance of coarticulation for improvedspeech-in-speech recognition is not evident. 2019-05-23 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1554498179209764 http://rave.ohiolink.edu/etdc/view?acc_num=case1554498179209764 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
