Abstract Details

2019, Master of Arts, Case Western Reserve University, Communication Sciences.
Listeners take advantage of linkage variables (e.g., talker voice & appropriate syntax) to help recognize target speech from competing background talkers. One potential linkage variable is coarticulation. Two experiments were conducted to investigate the role of coarticulation in speech-on-speech recognition. Experiment 1 results indicated a significant main effect of coarticulation in the target speech, where coarticulation did not benefit the listener. It was unclear, however, how differences in local signal-to-noise ratio (SNR) across keywords affected these results. In Experiment 2, local SNR was controlled for across keyword position. Results indicated no effect of coarticulation for the target speech regardless of local SNR. However, a significant main effect of masker type was observed, with listeners benefiting from the presence of a SSN compared to a two-talker masker. Data suggest that local intensity level plays a role in speech recognition, however the importance of coarticulation for improved speech-in-speech recognition is not evident.
