Configuraciones tonales de frases entonativas en enunciados aseverativos del español de la Ciudad de México

The objective of this paper is to describe the prosodic features of the final intonation contour of minor intonational phrases (ip) and the tonemes of major intonational phrases (IP) in Mexico City’s Spanish variety. The speech data was taken from a spontaneous speech corpus made from speakers from two social networks: neighborhood and labor. Final intonation contours of ip show a predominantly rising movement. These contours are generally produced with greater length in the last syllable of the ip, which represents the most significant difference between both networks in the case of oxitone endings. On the other hand, tonemes are predominantly descendant, although the circumflex accent has an important number of cases within the data set. Tonemes produced by the neighborhood network are produced with larger length than those from the labor network.
