The Speech Disorders Classification System (SDCS)

Abstract

A companion paper includes rationale for the use of 10 metrics of articulation competence in conversational speech (Shriberg, Austin Lewis, McSweeny, & Wilson, 1997). The present paper reports lifespan reference data for these measures using records from a total of 836 3- to 40(+)-year-old speakers with normal and disordered speech. The reference data are subdivided by diagnostic classification based on extensions to an instrument titled the Speech Disorders Classification System (SDCS; Shriberg, 1993). Appendices provide procedural information on the SDCS and statistical rationale for the reference data.

Aplicação de medidas de gravidade e de inconsistência de fala em crianças com transtorno fonológico

“…The greater the severity of the SSD, the more compromised speech intelligibility in children with substitutions and omissions, in comparison with those presenting distortions (8) . As there was no difference between the ages of the subjects of the two groups, the fact that there is a tendency to higher incidence of distortions in G1 (Table 1), it can not be attributed to maturational characteristics (25) , but to those relating to the residual errors (1,14,26) . These data suggest that the presence of the phonological process of devoicing may be associated with difficulty in understanding the phonological rule (27) .…”

“…Despite the characteristics necessary for a child to be diagnosed as having PD are well known, the current studies seek to detail the cause, severity, error type (substitution, omission and distortion) and prevalent Phonological Processes (PP), as well as subtypes of the disorder, which attribute to high heterogeneity (1) .…”

“…One of the most widely indexes used by national (7)(8)(9)(10) and International (1) authors is what measures the Percentage of Consonants Correct -Revised (PCC-R) (11) , which considers only substitutions and omissions as errors and evaluates distortions as correct. Process Density Index (PDI) (12,13) is an index of severity of SSD which supports the occurrence of PP.…”

Implicações da diadococinesia oral no transtorno fonológico

“…Despite the importance of these tasks for SSD diagnosis there is still the need to complement the diagnostic in order to provide more detailed information on individual speech development and to help on choosing the most adequate therapeutic model. Therefore, diagnosis of SSD involves the application of different tasks in an attempt to establish the speech severity (which can be measured by various indexes) (1) and the most affected ability during phonological acquisition: auditory perception, cognitive-linguistic processing or oro-motor speech processing (2)(3)(4) . Speech errors produced during language development may be related to children's ability to plan and execute complex sequences of fine oro-motor sequences required for the articulation of speech (3) .…”

Processamento auditivo em crianças com fala normal e desviante

“…It appears that several factors are involved in this disorder, such as sex, age, hearing loss, and the family context. [3][4][5][6] Oral language disorders, including phonological disorders, may be closely related with auditory processing disorders because hearing is the main entry path for language acquisition to be possible. [7][8][9] The changes encompassed by the term "auditory processing" may be described as difficulties in processing specifically auditory information, in hearing or understanding speech, and in developing language abilities and learning.…”
