“…However, from previous studies it remains unclear whether the difference in performance between SMR and AMR tasks is already evident in younger age groups or whether it follows an evolutionary pattern from childhood to adulthood, as has been reported for the syllabic rates of SMR and AMR tasks separately. Changes in performance between AMR and SMR from childhood to adulthood can hardly be inferred from previous studies since SMR and AMR tasks are not systematically tested in DDK studies (e.g., in children and adolescents [ 25 , 26 , 27 ], in adults [ 28 , 29 , 30 ] or whenever they are included, no comments on the performance pattern between the two types of DDK tasks is found (e.g., in children and adolescents [ 7 , 31 ] or in adults [ 13 , 14 ]). Additionally, most studies are carried out only on one age group or only on one type of DDK—mostly AMR—which does not inform of the changes in performance between AMR and SMR from childhood to adulthood.…”

Oral diadochokinetic (DDK) tasks are common research and clinical tools used to test oromotor skills across different age groups. They include alternating motion rate (AMR) and sequential motion rate (SMR) tasks. AMR tasks involve repeating a single syllable, whereas SMR tasks involve repeating varying syllables. DDK performance is mostly discussed regarding the increasing rates of AMR and SMR tasks from childhood to adulthood, although less attention is given to the performance differences between SMR and AMR tasks across age groups. Here, AMR and SMR syllabic rates were contrasted in three populations: 7–9-year-old children, 14–16-year-old adolescents and 20–30-year-old adults. The results revealed similar syllabic rates for the two DDK tasks in children, whereas adolescents and adults achieved faster SMR rates. Acoustic analyses showed similarities in prosodic features between AMR and SMR sequences and in anticipatory coarticulation in the SMR sequences in all age groups. However, a lower degree of coarticulation was observed in children relative to adults. Adolescents, on the contrary, showed an adult-like pattern. These findings suggest that SMR tasks may be more sensitive to age-related changes in oromotor skills than AMR tasks and that greater gestural overlap across varying syllables may be a factor in achieving higher rates in SMR tasks.

Purpose: The aim of this study was to conduct a scoping review of research on oral and laryngeal diadochokinesis (DDK) in children and adults, either typically developing/developed or with a clinical diagnosis. Method: Searches were conducted with PubMed/MEDLINE, Google Scholar, CINAHL, and legacy sources in retrieved articles. Search terms included the following: DDK, alternating motion rate, maximum repetition rate, sequential motion rate, and syllable repetition rate. Results: Three hundred sixty articles were retrieved and included in the review. Data source tables for children and adults list the number and ages of study participants, DDK task, and language(s) spoken. Cross-sectional data for typically developing children and typically developed adults are compiled for the monosyllables /pʌ/, /tʌ/, and /kʌ/; the trisyllable /pʌtʌkʌ/; and laryngeal DDK. In addition, DDK results are summarized for 26 disorders or conditions. Discussion: A growing number of multidisciplinary reports on DDK affirm its role in clinical practice and research across the world. Atypical DDK is not a well-defined singular entity but rather a label for a collection of disturbances associated with diverse etiologies, including motoric, structural, sensory, and cognitive. The clinical value of DDK can be optimized by consideration of task parameters, analysis method, and population of interest.

Objectives: Alternating motion rate (AMR) tests are usually used to investigate the mobility and function of articulators but it is controversial if AMR tests can predict articulatory skill reliably. The present study was performed to compare AMR test results when speakers produce normal and whispered speech which show different aerodynamic characteristics and to consider the reliability and practicality of the AMR method. Methods: 39 females (age of 18-23 years) who have no communication disorders performed AMR tests with normal and whispered speech. To confirm the aerodynamic difference between the two speech styles, mean expiratory airflow (MEA) and maximum phonation time (MPT) were measured. Results: Aerodynamic analysis showed that in whispered speech MEA was significantly higher and MPT was shorter. Among the three /p h ʌ/, /t h ʌ/, and /k h ʌ/ syllables, the repetition rate of /t h ʌ/ was highest, and /k h ʌ/ was lowest. /p h ʌ/ and /t h ʌ/ repetition rates were significantly lower in whispered speech, but /k h ʌ/ repetition rate was not significantly different between the two speech styles. Conclusion: Even with the same articulatory structures and mobility, if aerodynamic characteristics are different, AMR test results can be significantly different. So, to predict a speakerʼs articulation skills reliably by AMR tests, it is also necessary to take into account the speakerʼs aerodynamic characteristics.
