Este trabajo se realizó en el marco del proyecto AMPER. Se comparó la duración entreoraciones declarativas e interrogativas de voces femeninas de dos países fronterizos:Colombia y Venezuela. Se analizó la media de las oraciones en función de la tipologíaacentual, las diferencias mínimas perceptibles y, finalmente, se generó la estructura de la duración. Los resultados muestran que las tónicas tienden a ser significativamente más largas que las vocales adyacentes. Pero, Colombia a diferencia de Venezuela, presenta una mayor duración y su estructura difiere entre las modalidades.

This work has been carried out within the framework of the project Comparative study of intonation and accent in Spanish border areas (FFI2014-52716-P), which is associated to AMPER (Atlas Multimédia Prosodique de l'Espace Roman). The objective of this paper is undertaking a phonetic-phonological study of declarative sentences (La Gomera, Canary Islands) uttered in two different speaking styles; i.e. formal and spontaneous. Sentences were analyzed using Matlab sub-routines (López Bobo et al, 2007) to extract F0 values from the syllables' nuclei. The phonetic-phonological tagging follows the rules of the Sp_ToBI system according to the proposal by Dorta ed. (2013). A psycho-acoustic threshold of 1.5 semi-tones (Rietveld y Gussenhoven, 1985; Pamies Bertrán et al., 2002) was used to quantify the importance of tonal variations. Results obtained allow consolidating and broadening the proposal for phonologic tagging in Spanish by Dorta ed. (2013) that distinguishes three mono-tonal and two bi-tonal invariants with their corresponding variants for tonal accents in the study areas considered.
