This paper reports an acoustic study in which Spanish speaker's productions of the vowel /a/ in contact with /a e i/ in word boundaries were obtained during the reading of texts. All tokens were measured for vowel quality (F1/F2) and duration. The obtained data allowed us to classify the observed phonetic results according to phonological processes (hiatus, reduction, monophthongization) and the duration values were statistically processed in order to investigate the effects of some segmental and prosodic conditions on vowel sequences pronunciation. The primary purpose of the study was to provide data for Peninsular Spanish showing the differences between the phonetic outputs of several vowel combinations across word boundaries in a experimental setup.
