Speech Therapy Considerable research has been done assessing the effects of the acoustic reflex (AR) on speech intelligibility (SI). There has not been good agreement on whether the AR enhances SI or not. A primary method of analysis of the effects of the AR on SI was a simple count of speech errors comparing ears with functioning and non-functioning ARs. A more detailed analysis has not been done. The purpose of this research was to analyze the effects of the AR on SI by comparing a simple count of speech errors and doing a distinctive feature analysis of speech stimuli as they were affected by the AR. Subjects with unilateral ARs were used. Comparisons were made between the ear with the AR and the non-reflex ear at 70, 95, and 110 dB SPL, using specially constructed pre-vocalic, consonant-vowel (CVs) syllables. The CVs were mixed in a low pass noise. Significant differences were found between the two ears at all intensity levels of the tests. The distinctive feature analysis revealed marked quantitative differences between the ears. Qualitatively, the two ears were very similiar. It was concluded that stapedius muscle contraction and an intact stapedius muscle are important to SI. The results also suggested that tests of speech discrimination of patients who have had stapedectomies ought to be more rigorously evaluated. Furthermore, a distinctive feature analysis of the data better reveals the true nature of the effects of the AR on SI. 1978 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566463048517284 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566463048517284 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
