Abstract

This study used a group of ten listeners with no previous exposure to artificial larynx speech to judge the intelligibility of Western Electric No. 5 speakers across varying noise conditions with audio versus audiovisual modes of presentation. Percentage scores across the conditions showed a decrease in intelligibility in the audio condition and a further decrease when noise was introduced. Percentage scores for the best condition (audiovisual plus a high signal to noise ratio) were low due to the listeners' unfamiliarity with artificial larynx speech. Further analysis of listener responses indicated a proximity to the target response. Implications of these findings are discussed.
