Análisis acústico de la africada postalveolar sorda en el español del norte del estado de Sinaloa

This paper addresses the acoustic analysis of the voiceless postalveolar affricate in the northern part of the state of Sinaloa. The duration characteristics of the phoneme are described, both for the occlusion period and for the friction period, and the total length is presented in the productions of both men and women in the region. The data are compared with the work of Herrera (2006) on the weakening of postalveolar voiceless affricate in two varieties of American Spanish, Panamanian and Mexican. From this comparison, it is found that the duration of the total segment in Sinaloa is longer, and the phenomenon of weakening reported by the author in the varieties she studied does not. Rather, the period of occlusion in the phoneme produced by the Sinaloan people is much longer, as is the period of friction, which is greater in the case of women.
