“…Although, norm values of oral-DDK rate for repeating meaningless syllable strings are available in most languages, it can be altered by different factors like age, language context, culture, and gender. The oral-DDK values for repeating nonsense string /pa-ta-ka/ in some languages (e.g., Portuguese, English, Persian, Greek, and Hebrew) are summarized in Table 1 (Icht and Ben-David 2014; Padovani et al. 2009; Robb et al.…”

Repetitive articulatory rate or Oral Diadochokinesis (oral-DDK) shows a guideline for appraisal and diagnosis of subjects with oral-motor disorder. Traditionally, meaningless words repetition has been utilized in this task and preschool children have challenges with them. Therefore, we aimed to determine some meaningful words in order to test oral-DDK in Persian speaking preschool children. Participants were 142 normally developing children, (age range 4–6 years), who were asked to produce /motæka, golabi/ as two meaningful Persian words and /pa-ta-ka/ as non-word in conventional oral-DDK task. We compared the time taken for 10-times fast repetitions of two meaningful Persian words and the tri-syllabic nonsense word /pa-ta-ka/. Praat software was used to calculate the average time that subjects took to produce the target items. In 4–5 year old children, of time taken for 10-times repetitions of /pa-ta-ka, motæka, golabi/ were , and seconds respectively, and in 5–6 year old children were , and seconds respectively. Findings showed that the main effect of type of words on oral diadochokinesis was significant (). Children repeated meaningful words /motæka, golabi/ faster than the non-word /pa-ta-ka/. Sex and age factors had no effect on time taken for repetition of oral-DDK test. It is suggested that Speech Therapists can use meaningful words to facilitate oral-DDK test for children.

“…Because the RDA includes internationally accepted speech tasks and terminology, the instrument can easily be translated into other languages, with two possible limitations: every language may need its own set of videos with all dysarthria types and severities, and only future data gathering can demonstrate whether or not the reference values of the speech tasks are language dependent [34]. …”

Objective: In the absence of an adequate dysarthria assessment in the Netherlands, we developed the Radboud Dysarthria Assessment (RDA). This article describes its development and clinimetric evaluation. Patients and Methods: Forty-three patients were assessed with the RDA. The recording forms were subjected to exploratory factor analysis and estimation of internal consistency. The self-evaluation questionnaire was tested for internal consistency and the severity scale for intra- and inter-rater reliability. Construct validity of the severity scale and questionnaire was determined by relating them to the Speech Handicap Index (SHI), Dutch sentence intelligibility assessment (NSVO-Z), and category fluency task. Results: Exploratory factor analysis extracted 4 factors (articulation, resonance, phonation, respiration/prosody) yielding an explained variance of 70.3%. Each factor showed good internal consistency (Cronbach’s α: 0.89–0.91). The self-evaluation questionnaire showed excellent internal consistency (Cronbach’s α: 0.90). Intra-class correlation coefficients of the severity scale (0.85–0.86) showed good reliability. The severity scores and self-evaluation questionnaire correlated substantially to strongly with the SHI (r_s = 0.40 and 0.80) and substantially with the NSVO-Z (r_s = –0.65 and –0.52). Conclusions: The RDA is a valid and reliable tool, but further investigation is needed to demonstrate whether this instrument can successfully support speech-language therapists in correctly diagnosing the type of dysarthria.

“…the ease with which such tasks can be studied; Weismer, 2006: 343), but often also a belief that such tasks are informative about speech (Riecker et al, 2005). They allow for systematic, controlled manipulation of complexity (Hurkmans et al, 2012) and relatively language-independent assessment of articulation abilities (Icht & Ben-David, 2014), which may be important when assessing bilingual speakers or making cross-linguistic comparisons.…”

Speech and nonspeech: What are we talking about?

Understanding of the behavioural, cognitive, and neural underpinnings of speech production is of interest theoretically, and is important for understanding disorders of speech production and how to assess and treat such disorders in the clinic. This paper addresses two claims about the neuromotor control of speech production: (1) speech is subserved by a distinct, specialised motor control system, (2) speech is holistic and cannot be decomposed into smaller primitives. Both claims have gained traction in recent literature, and are central to a task-dependent model of speech motor control (Ziegler, 2003a). The purpose of this paper is to stimulate thinking about speech production, its disorders, and the clinical implications of these claims. The paper poses several conceptual and empirical challenges for these claims – including the critical importance of defining speech. The emerging conclusion is that a task-dependent model is called into question as its two central claims are founded on ill-defined and inconsistently applied concepts. The paper concludes with discussion of methodological and clinical implications, including the potential utility of diadochokinetic (DDK) tasks in assessment of motor speech disorders and the contraindication of nonspeech oral motor exercises to improve speech function.
