“…Comparing these findings with the previous study involving just normal speakers, which found ICCs of 0.85 (sentences) and 0.71 (single words) [12], it is observed that the agreement among raters was greater when dysarthric speakers were included in the analysis.…”

“…The CG comprised 30 healthy speakers selected from the population of patient escorts and graduate and postgraduate UNIFESP students, all of whom had participated in a previous study [12]. The participants in this group were native speakers of Brazilian Portuguese, aged 18-60 years with a mean age of 40.4 years (SD = 13.2), 11.4 years of education (SD = 4.0) and a gender ratio of 1:1.…”

“…The sentences contained an average of 5 words and 9 syllables. The single word list was created from the list of sentences and they presented very strong correlations in terms of distribution of frequency of phonemes, word length and type of syllabic structure involved (0.99-1.00) [12]. …”

“…As an instrument for assessing intelligibility in Brazilian dysarthric speakers, the Protocol for the Evaluation of SI (PESI) has been proposed based on a critical review of the literature [6] and on a study with normal speakers that investigated the influence of stimuli type and transcription analysis on intelligibility measures [12]. The present study assessed inter-rater reliability, internal consistency and criterion validity of scores for the sentences and words subtests of the PESI in dysarthria, with the aim of contributing to an improved selection and interpretation of intelligibility measures employed in both clinical and research settings.…”

Background/Aims: Studies about the reliability and validity of intelligibility measures are fundamental to direct their use and interpretation in both clinical and research settings. The present study assessed inter-rater reliability, internal consistency and criterion validity of scores for the sentence and word subtests of the Protocol for the Evaluation of Speech Intelligibility (PESI). Methods: This study included 180 adult volunteers who were divided into three groups: 30 speakers with dysarthria, 30 control speakers and 120 listeners. Intelligibility scores were calculated according to the percentage of words correctly transcribed in each subtest: words in sentences and single words. Results: The intelligibility measurements exhibited a high level of inter-rater reliability for sentences [intraclass correlation coefficient (ICC) = 0.94] and for single words (ICC = 0.96). The items from the single words subtest of the PESI revealed high internal consistency (Cronbach's alpha = 0.93). The measurement of intelligibility of sentences and single words had a high discriminatory power (0.82 and 0.95, respectively), with high sensitivity and specificity, particularly for scores in the single words subtest. Conclusion: This study provides preliminary evidence of the reliability and validity of the PESI.

This method involves the transcription of speech stimuli by the listener and assigning a score or percentage of correctly or incorrectly decoded items (Barreto & Ortiz, 2010). 2 Normal-hearing peers show a typical sequence of these expressive skills.…”

Children who use cochlear implants (CI) and who are readers usually produce more accurate speech in response to text than to pictures. Equivalence-based instruction (EBI) can be a route to establish functional interdependence between these verbal operants. The present study investigated whether children with CI who read would improve speech accuracy when tacting pictures of scenes after EBI that included dictated sentences, pictures of scenes, and printed sentences. This study evaluated whether teaching verbal relations to diagonal sentences from a matrix with subject-verb-object combinations promoted recombinative generalization to untrained sentences. Participants were three children with CI with a more accurate speech when reading print than when tacting pictures of scenes. They were taught to select pictures of scenes in response to dictated sentences (AB) by matching-to-sample (MTS) and to construct printed sentences in response to dictated sentences (AE) by constructed-response-matching-to-sample (CRMTS). Speech production in response to print (CD) and in response to pictures of scenes (BD) were probed for both trained and untrained sentences, using a multiple baseline design across participants. All participants learned the trained relations, showed emergence of derived relations, and improved speech accuracy when tacting pictures of scenes. They were able to recombine sentence components and tact novel pictures using untrained sentences from the matrix. These results indicate that speech accuracy and generative sentence production can be improved in children with CI from interventions that incorporate EBI and matrix training.
