Consonant Intelligibility: A Procedure for Evaluating Speech in Oral Cleft Subjects

Medidas de inteligibilidade nos distúrbios da fala: revisão crítica da literatura

“…Item identification methods involve multiple formats according to the type of response required to identify speech stimuli. Some variations on each of these methods can be found (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(13)(14)(15)(16)(17)(18)20,21,23,(27)(28)(29).…”

“…Methods of identifying items can entail orthographic transcription of speech stimuli by the listener (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(13)(14)(15)(16)(17)(18)20,21,23,(27)(28)(29) or the selection of alternatives using a multiple-choice format (1,7,14,23). There are variations on the orthographic approach such as: partial(5,7,18) (for example, only target phonemes of each word) or full transcription of speech samples (2)(3)(4)(6)(7)(8)(9)(10)(11)(13)(14)(15)(16)18,20,21,23,(27)(28)(29), and tally of target stimuli only (2,4,5,…”

“…Besides the issue of the diversity of methods available, another important aspect is the influence certain variables can have on these measures (1,2). A number of studies on the intelligibility of speech have addressed the effects of several of these variables including: the task employed for speech sample collection(5), the stimulus type used (3,4,(6)(7)(8)(9)(10)(11)(12)(13)(14), the mode in which samples are presented (11,13,(15)(16)(17), the response type required to identify the stimuli (7,18), the type of transcription analysis(2), the gender of the listener or rater (13,19), or their familiarity with the speaker(s) (9,11,13,20,21)).…”

Reliability and Validity of a Computer-Mediated, Single-Word Intelligibility Test: Preliminary Findings for Children with Repaired Cleft Lip and Palate

“…McWilliams et al (1990) observed that early studies that investigated intelligibility in children with repaired cleft palate employed item identification via transcription or write-down techniques (e.g., Prins and Bloomer, 1965, 1968; Fletcher, 1978). In general, these studies indicated a) clear differences in intelligibility between individuals with and without cleft palate, b) a tendency for articulation and intelligibility scores to be correlated (especially errors involving stop consonants), and c) a tendency for intelligibility and velopharyngeal (VP) function to be related.…”

The Speech Handicapped

“…Nichols (1967) evaluated three published and five unpublished articulation screening tests and found them all reliable, but varied in their pass-fail criteria. Prins and Bloomer (1968) developed a consonant intelligibility test. Gilmore and Familant (1967) found some pictures in the widely used Templin-Darley Screening and Diagnostic Tests of Articulation to be inappropriate for eliciting responses from a lower socioeconomic population in the South.…”
