In this study, I examine sorne of the articulatory and acoustic properties present in the phonetic realization of glottal stops. In particular, I focus on two tendencies languages show when they realize this type of segments: full closure of the vocal folds and creaky voice. I show through examining the language Boruca that creaky voice can occur without the aperiodic vibration ofthe vocal folds. In this language, a decrease of the fundamental frequency and intensity can serve alone as a phonetic cue to detect creaky voice. I also examine the influence that prosodic structure can have on restricting the spreading of creaky voice within a vowel. Particularly, 1 present the cases of two Panoan languages, Capanahua and Shipibo, in which vowels of syllables in strong prosodic positions tend to resist having creaky voice throughout their duration. In contrast, vowels that belong to weak sylla...

This article studies the role that stress, and the word-initial syllable has on the spirantization of the intervocalic voiced stops in the Spanish of Lima. Through the analysis of how frequently the stop and approximant allophones of the voiced stops occur and intensity ratio measurements of those allophones, the study found out that there is an asymmetry between the spirantization patterns of non-velar and velar stops. It was also found out that the interaction between stress and the word-initial syllable can inhibit the spirantization of /b, d/ up to a certain degree, and that stress can increase the amount of constriction of their approximant allophones, [β, ð]. Those same prosodic factors do not have any effect on the spirantization of /ɡ/. It regularly surfaces as the velar approximant, [ɣ], in intervocalic environments.

Many languages categorize their syllables causing them to behave in a special way. One such behavior is accent attraction; thus, for example, in languages such as Latin or Koya, CVC and CVV syllables cause the accent to appear on them, while CV syllables do not exhibit this behavior. Traditionally, this behavior has been viewed as a difference in syllable weight. Those syllables that attract stress have been called heavy syllables; while those that do not, light syllables. But how can we formally account for this categorization? The moraic theory proposes a formal explanation for this behavior by resorting to the mora (µ). Thus, a heavy syllable is bimoraic (=2µ); while a light syllable is monomoraic (=1 µ). In other words, the factor that determines syllable weight is the number of morae or moraic content. Another assumption generally made by this theory is that a syllable is maximal...

Esta investigación se centra en el estudio de las estructuras silábicas que muestran divergencias cuando se compara el habla del modelo adulto con el habla de niños limeños monolingües del castellano hablado en Lima. También busca determinar hasta qué edad subsisten dichas divergencias en el habla de los niños entre los dos años y medio y los cinco años y que no pre sen tan aparentes limitaciones articulatorias, auditivas o intelectuales. Uno de los principales resultados de este trabajo es la identificación del momento en que se produce una disminución significativa en este tipo de divergencias, la mayoría de las cuales desaparecen entre los dos años y medio y los tres años y medio. Sin embargo, los casos de diptongación pueden subsistir hasta los cuatro años de edad.
