“…Participants with ALS were grouped into three severity groups on the basis of speaking rate, which was measured using the Speech Intelligibility Test (Yorkston, 1993;Yorkston, Dowden, & Beukelman, 1992). The mild group included patients with speaking rates greater than 160 WPM; the moderate group included patients with speaking rates between 120 and 160 WPM; and the severe group of participants had a speaking rate less than 120 WPM.…”

Purpose: The goal of this study was to identify the effects of amyotrophic lateral sclerosis (ALS) on tongue and jaw control, both cross-sectionally and longitudinally. The data were examined in the context of their utility as a diagnostic marker of bulbar disease. Method: Tongue and jaw movements were recorded crosssectionally (n = 33 individuals with ALS, 13 controls) and longitudinally (n = 10 individuals with ALS) using a threedimensional electromagnetic articulography system during the production of the sentence Buy Bobby a puppy. The movements were examined for evidence of changes in size, speed, and duration and with respect to disease severity and time in the study.Results: Maximum speed of tongue movements and movement durations were significantly different only at an advanced stage of bulbar ALS compared with the healthy control group. The longitudinal analysis revealed a reduction in tongue movement size and speed with time at early stages of disease, which was not seen cross-sectionally. As speaking rate declined, tongue movements decreased in maximum speed, whereas jaw movements increased in maximum speed. Conclusions: Longitudinal analyses of sentence-level kinematic data show their sensitivity to early bulbar impairment. A change in articulatory kinematics can serve as a useful diagnostic marker for bulbar ALS and to track bulbar disease progression in a clinical setting.

“…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). Moreover, linguistic aspects such as context, redundancy, syntactic complexity of the utterance, and the use of ungrammatical structures may also influence speech intelligibility (Garcia & Dagenais, 1998;Yorkston, Dowden, & Breukelman, 1992). In addition, the relationship between intelligibility and articulation errors in cleft palate speech is not altogether clear (Subtelny, Van Hattum, & Myers, 1972).…”

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.

“…Standard protocols containing speaker tasks, recording techniques, and listener response formats are employed to obtain a variety of intelligibility and communication efficiency measures. Yorkston and co-workers (1993) initially suggested that PALS speaking rate reduction precedes decreases in intelligibility; co-workers (2001, 2002) reported that speaking rate on the Speech Intelligibility Test -Sentence Subtest (Yorkston et al, 2007) is a relatively good predictor of PALS intelligibility deterioration. This computerized test supports the efficient measurement of speaking rate in clinical settings; it helps patients and their families monitor changes over time, and reinforces their understanding of speaking rate and intelligibility.…”

“…Indeed, appropriate timing of referral for AAC assessment and intervention continues to be a relevant clinical decision-making issue. The speaking rate should be clinically monitored so that the referral for an AAC intervention is initiated in a timely manner: co-workers (2001, 2002) recommend that patients be referred for AAC assessment when their speaking rates reach 125 words/min (normal value: 190 words/min) on the Speech Intelligibility Test -Sentence Subtest) (Yorkston et al, 2007). With sufficient education and preparation, PALS and their caregivers are ready to examine their AAC options timely: nevertheless, speech deterioration can be so rapid anyway that individuals can be left with limited communication options, if they are not really prepared to act in an opportune manner.…”
