Variación geoprosódica en dos entonaciones de Castilla y León: análisis de frases declarativas e interrogativas sin expansión

In this paper we offer the first results of the acoustic analysis corresponding to a part of an experimental corpus obtained from the records of sentence reading by
two female informants (from the cities of Valladolid and Salamanca, respectively).
The main differences can be found in the interrogative intonation. The interrogative sentence of Valladolid is lesser high in the nucleus than the interrogative sentence of Salamanca, especially in the case of the words stressed in the penultimate and, mainly, in the antepenultimate syllables, where the pitch rising is higher than an octave. As regards the prenucleus, it seems, on the other hand, that the peak raises more in the interrogative sentence of Valladolid. In the declarative sentences, clear differences can be found in the nucleus, which shows a bigger falling in the intonation of Valladolid (mainly, in words stressed in both the last and the antepenultimate syllables).
As for prosodic values of duration and energy, we have observed differences in the interrogative modality, where the Salamanca informant lengthens vowels and registers a light increase of energy.
