“…Although the topic of speech intelligibility has been of great interest and concern to professionals and researchers concerned with several other impairment, such as motor speech disorders and hearing impairment, it has been studied less in children with cleft palate. Authors who omitted speech intelligibility from their framework did so because of reliability and validity issues (Sell, Har-ding, & Grunwell, 1994;Wyatt, Sell, Russell, Harding, Harland, & Albery, 1996). An additional reason for omitting this variable is that it is not only influenced by cleft-related variables, but also by intonation, accent, stress, and rate (Wyatt et al, 1996).…”

Research into intelligibility of individuals who are hearing impaired or have motor speech disorders has shown that suprasegmental factors, such as phonatory control, timing, and speech rate, affect intelligibility (Olson Ramig, 1992;Weismer & Martin, 1992).…”

A randomized, prospective, clinical study was performed investigating the effects of presurgical infant orthopedic treatment (PIO) in children with unilateral cleft lip and palate (UCLP). The influence of PIO on speech intelligibility was evaluated with two groups, each consisting of 10 children with UCLP. One group used PIO during the first year of life, whereas the other group did not use the device. Eight children without cleft served as a second control group. Intelligibility was assessed by lay listeners using two methods: transcription and listener rating. The ratings proved to be reliable and to have sufficient validity, but they did not completely reflect intelligibility defined as the proportion of words understood by the listener. Children in the treatment group were rated as exhibiting greater intelligibility than those in the nontreatment group. However, data obtained by means of transcriptions indicated that, in fact, there were no group differences in actual intelligibility. Only in comparison with their noncleft peers were the children with cleft lip and palate significantly less well understood. © 2000 by Elsevier Science Inc.Educational Objectives: Readers will learn about (1) the reliability and validity of a rating paradigm used for assessing intelligibility of children with UCLP and (2) the relationship between the use of PIO and intelligibility in toddlers with UCLP.

“…Among these variable, we highlight the individual characteristics of the speech stimuli used for capturing the speech samples to be judged; the procedures for the perceptual evaluation; the choice of statistical methods for comparison, among other variables (5,11,12,17,18) . In the present study, care was taken to select participants with the same type of cleft, operated by the same surgeon, within the same age range, in an attempt to minimize external variables that can impact the results of assessment of nasality after primary palatoplasty for correction of cleft lip and palate.…”

“…The difficulty in obtaining reliable judgments has been evidenced in the literature since the auditory-perceptual assessment of nasality has proven to be a challenging task (6,10,17,19,20) . In this study, there were differences regarding the identification of hypernasality between live perceptual assessment (as retrieved from patient´s charts) and auditory-perceptual judgements of recorded samples established by judges, particularly for HPC speech sample.…”

“…NAE, also referred to as nasal escape or nasal emission, occurs when air leaks from the oral cavity into the nasal cavity, either due to a gap in the VP port at times when the port should be tightly closed or due to an oronasal fistula (Kummer, 2008;Wyatt et al, 1996). NAE is particularly noticeable during voiceless obstruents such as /p t k s f ʃ θ/, in which the speaker attempts to build up pressure in the oral cavity that is needed for intelligible production of the phoneme.…”

,ePurpose: This article describes the development and initial validation of an objective measure of nasal air emission (NAE) using nasal accelerometry. Method: Nasal acceleration and nasal airflow signals were simultaneously recorded while an expert speech language pathologist modeled NAEs at a variety of severity levels. In addition, microphone and nasal accelerometer signals were collected during the production of /pɑpɑpɑpɑ/ speech utterances by 25 children with and without cleft palate. Fourteen inexperienced raters listened to the microphone signals from the pediatric speakers and rated the samples for the severity of NAE using direct magnitude estimation. Mean listener ratings were compared to a novel quantitative measurement of NAE derived from the nasal acceleration signals.Results: Correlation between the nasal acceleration energy measure and the measured nasal airflow was high (r = .87). Correlation between the measure and auditory-perceptual ratings was moderate (r = .49). Conclusion:The measure presented here is quantitative and noninvasive, and the required hardware is inexpensive ($150). Future studies will include speakers with a wider range of NAE severity and etiology, including cleft palate, hearing impairment, or dysarthria. Further development will also involve validation of the measure against airflow measures across subjects.
