To reach this objective, the oral diadochokinetic parameters were evaluated through monosyllabic repetition of [pa], [t̪a] and [ka] using the syllable emission method in a specific time. The syllable emission analysis was carried out through the Motor Speech Profile program, which provided with measurement values for five diadochokinetic parameters (DDKavp, DDKavr, DDKcvp, DDKjit, DDKcvi). On the other hand, the phonetic-phonological performance was analyzed through the Classification of Phonetic and Phonological Adjustments (CLAFF). The results showed differences between both sociocultural groups only for the parameters DDKcvp/%/ y DDKjit/%/, while the other diadochokinetic parameters behaved in a similar way. The low sociocultural children group had a higher variability in the DDK parameters and a higher percentage of disturbances. Significant relations could be seen between some phonetic-phonological adjustments and some diadochokinetic parameters.
