Purpose: the objective of this study was to establish an associative factor that connects the morphology of the skull--cervical system with the articulatory intelligibility level of speech in young subjects. Methods: cross-sectional study. It considered a sample of 42 university students from a universe of 140, both male and female, without morbid background and of an age range in between 18 and 21 years. Evaluated aspects: a) articulatory intelligibility by the diadochokinetic periodic variation coefficient, b) traditional static postural parameters using the photogrammetric method and c) cephalic postural pattern by lateral cephalometric radiograph Results: 36 subjects with adequate intelligibility and 6 having altered intelligibility where cervical antero-posterior skull rotation variable showed statistically noteworthy differences (p = 0,009) in between the group with normal intelligibility compared to the group with impaired intelligibility. The linear regression analysis showed that subjects with posterior rotation of head on neck show more variability in the syllabic emission of speech diadochokinetic performance (Sq r lineal = 0,128). Conclusion: it is established that cephalic position with subsequent posterior rotation of the head on the neck is associated with loss of speech intelligibility in the sample studied.

Metodos: estudio transversal, considero una muestra de 42 jovenes universitarios de un universo de 140, ambos sexos, sin antecedentes morbidos y con un rango de edad entre 18 y 21 anos. Se evaluo: a) inteligibilidad articulatoria mediante el coeficiente de variacion periodica diadococinetica, b) parametros posturales estaticos tradicionales mediante metodo fotogrametrico y c) patron postural cefalico mediante radiografia cefalometrica lateral. Resultados: se encontraron 36 sujetos con inteligibilidad adecuada y 6 alterada, donde la variable rotacion craneo cervical antero-posterior presento diferencias estadisticamente significativas (p= 0,009) entre el grupo con inteligibilidad normal respecto al grupo con inteligibilidad alterada. El analisis de regresion lineal evidencio que sujetos que presentan rotacion posterior de cabeza sobre cuello presentan mayor variabilidad en
