Résumé
The aim of this paper is to compare the multimodal production of assertions and questions in two different languages: Brazilian Portuguese and Mexican Spanish. Descriptions of the auditory and visual cues of these speech acts are presented based on Brazilian and Mexican corpora. The sentence "Como você sabe" was produced as an assertion and an echo question by ten speakers (five male) from Rio de Janeiro and the sentence "Apaga la tele" was produced as an assertion and a yes-no question by five speakers (three male) from Mexico City. The speech acts intonational patterns were described in terms of F0 movements and annotated in the nuclear region of the contours with ToBI system. Momentary facial muscular changes (namely Action Units) located in the upper and lower part of the face as well as head movements were used to analyze the facial expressions. The acoustic description showed that Brazilian Portuguese assertions are produced with a falling F0 nuclear configuration (H+L*L%) and echo questions with a rising F0 nuclear configuration (L+
