“…Further, under given conditions there may be considerable differences in intelligibility among sentences within a pool of sentences. This is reflected in the significant difficulties encountered when creating lists of sentences that are equal in intelligibility (Bilger, Neutzel, Rabinowitz, & Rzeczkowski, 1984;Giolas & Duffy, 1973;Hood & Dixon, 1969;Rippy, Dancer, & Pittenger, 1983;Webster, 1984). This difficulty exists in creating sentence materials for speech reading as well (Hinkle, 1978;Wilson, Dancer, & Stamper, 1984).…”

Purpose-The extent to which a sentence retains its level of spoken intelligibility relative to other sentences in a list under a variety of difficult listening situations was examined.Method-The strength of this sentence effect was studied using the Central Institute for the Deaf Everyday Speech sentences and both generalizability analysis (Experiments 1 and 2) and correlation (Analyses 1 and 2).Results-Experiments 1 and 2 indicated the presence of a prominent sentence effect (substantial variance accounted for) across a large range of group mean intelligibilities (Experiment 1) and different spectral contents (Experiment 2). In Correlation Analysis 1, individual sentence scores were found to be correlated across listeners in each group producing widely ranging levels of performance. The sentence effect accounted for over half of the variance between listener-ability groups. In Correlation Analysis 2, correlations accounted for an average of 42% of the variance across a variety of listening conditions. However, when the auditory data were compared to speech-reading data, the cross-modal correlations were quite low.Conclusions-The stability of relative sentence intelligibility (the sentence effect) appears across a wide range of mean intelligibilities, across different spectral compositions, and across different listener performance levels, but not across sensory modalities. Keywords sentence intelligibility; generalizability analysis; CID sentencesThe intelligibility of sentences is very high when spoken by typical talkers to listeners with normal hearing. However, under difficult listening conditions, such as those imposed by poor signal-to-noise ratio, filtering, or hearing loss, intelligibility may be reduced substantially. Further, under given conditions there may be considerable differences in intelligibility among sentences within a pool of sentences. This is reflected in the significant difficulties encountered when creating lists of sentences that are equal in intelligibility (Bilger, Neutzel, Rabinowitz, & Rzeczkowski, 1984;Giolas & Duffy, 1973;Hood & Dixon, 1969;Rippy, Dancer, & Pittenger, 1983;Webster, 1984). This difficulty exists in creating sentence materials for speech reading as well (Hinkle, 1978;Wilson, Dancer, & Stamper, 1984). Because of learning effects associated with being exposed to a sentence twice, such lists are desirable when the performance of one individual is to be assessed under a variety of conditions. NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author ManuscriptDifferences in intelligibility are even more apparent when individual sentences are considered. Healy and Warren (2003), for example, presented the 100 Central Institute for the Deaf (CID; Davis & Silverman, 1978) Everyday Speech sentences through narrow-band filters and found that the mean sentence intelligibility (key words correct per sentence) from the least intelligible to the most intelligible of the 100 sentences ranged over 80 percentage points within each of several listening conditions.Many...

Post-lingual deaf adults can develop some vocal abnormalities similar to those developed in pre-lingual deaf individuals. The aim of this work was to study the effect of cochlear implantation followed by post-operative rehabilitation on voice acoustics in post-lingual hearing impaired adults with different durations of hearing loss. The study included 35 post-lingual hearing impaired adults who underwent cochlear implantation. Patients were divided into two groups according to the duration of their hearing loss. Each group was further divided into two subgroups according to whether they received auditory rehabilitation or not. Using the Multi-Dimensional Voice Program (MDVP) parameters, comparisons were made between each subgroup of patients and the normal MDVP Saudi database, and between subgroups of patients. Most of the patients in the two groups reported significant improvement in their MDVP results post-implantation. Further, significantly deviant MDVP parameters were reported in the group of patients with longer duration of hearing loss. Patients who received rehabilitation significantly improved more than those who did not. In conclusion, it appears that cochlear implantation improves the auditory control of voice production in post-lingual deaf adults. Also, it is obvious that cochlear implantation at an early stage of hearing loss gives better results on voice control, especially if augmented with auditory rehabilitation.

“…Hood and Dixon (1969) rearranged the original ESS lists to make sentence length and surface structure be more consistent with the CHABA criteria (Hinkle, 1979). The sentences provide information about the time domain of everyday speech, and listeners can use contextual cues of conversational speech.…”

DEDICATIONTo my parents, Ungan and Saeko Kanekama v ACKNOWLEDGMENTS There were many dark nights that I cried for…. and there were many bright days that I smiled for…. The writing of a dissertation can be a lonely and isolating experience, however, it is clearly not possible without the mental and physical support of my family, my American family, the faculty and staff of the CSD Department, the members of my committee, and my fellow doctoral students. poorer SNRs than at favorable SNRs. The novel finding of this study, however, was that Indian participants benefitted less from speechreading than American participants at poorer SNRs, but benefitted more from speechreading than American participants at favorable SNRs. Linguistic (and, possibly, nonlinguistic) variables may have accounted for these findings; including an increased need for Indian participants to integrate more auditory cues with visual cues to benefit from speechreading, presumably because they only spoke English as a second language. These findings have theoretical implications for understanding the role of auditory-visual integration on cross-language perception of speech, and practical implications for understanding how much speechreading helps people understand a second language in noisy environments.
