Resumen de Acoustic analysis of rhotics in coda position in five- to seven-year-old children

Jordi Cicres i Bosch, Sílvia Llach Carles

• This article studies the acoustic production of central Catalan rhotics in a group of 90 boys and girls between the ages of five and seven, in medial and final coda. An acoustic description is provided based on an analysis of the number and type of components of both the closing and opening phases. Based on combinations of different components, up to 78 different rhotic types were detected. The results show that most rhotic sounds have one or two components, and that rhotics with five or more components are almost always at the end of a word. There is variability with respect to acoustic properties, with a higher presence of vocalic components in the medial coda and more fricative or occlusive components in the final coda.
