    Aquest estudi preliminar analitza com interactuen els educadors amb els nens de 3-6 anys per caracteritzar la parla dirigida a nens (IDS) en català posant una atenció especial a les característiques fonètiques del to i la intel·ligibilitat. Per tal de fer-ho, comparem les veus de 8 mestres parlant amb un adult i amb nens. Per cada participant i condició, hem anotat en Praat entre 2-6 minuts de conversa i hem extret el to mitjà, la variabilitat (utilitzant la desviació estàndard i el Pitch Dynamism Quotient) i el pendent espectral. Després utilitzem models mixtos generalitzats a R per provar l’efecte de la condició (IDS). Els resultats estan en línia amb els estudis previs per a altres llengües i mostren que l’IDS és més agut (to mitjà més alt), de to més variable (desviació estàndard i PDQ més alts) i més intel·ligible (amb un pendent espectral menys pronunciat i formant de locutor).

    This preliminary work analyzes how Catalan educators interact with children aged from 3-6 in order to characterize child-directed speech (IDS) phonetically paying special attention to pitch and intelligibility features. In order to do it, we compared the voices of 8 female teachers speaking with an adult and with children. For each participant and condition, we have annotated in Praat between 2 and 6 minutes of conversation and extracted its mean pitch, pitch variability (using both standard deviation and Pitch Dynamism Quotient) and spectral slope, then we used Generalized Mixed Models in R to test the effect of the child-directed speech condition. The results are in line with previous studies for other languages and show that CDS higher in pitch (higher pitch mean), more variable (higher standard deviation and PDQ) and more intelligible (a less steep spectral slope and speaker’s formant).
