Prominence and centralization: a two-way contrast between lexical and epenthetic non-labial high vowels in Algherese Catalan
2015
Algherese Catalan has the peculiarity of presenting an inserted [i] vowel across words in order to avoid certain consonant codas. In this study, we compare five acoustic features of this epenthetic segment (i.e., duration, intensity, and the three first formants) with those of lexical /i/ vowels, both stressed and unstressed. The results indicate that the three vowels present differences only with respect to duration, F2 and, to a lesser extent, F3. The second formant values decline progressively from the lexical stressed vowels to the inserted unstressed segments, with lexical unstressed segments at an intermediate point. This gradation mirrors the relative prominence of each vowel. The di…
Measures of native and non-native rhythm in a quantity language.
2005
The traditional phonetic classification of language rhythm as stress-timed or syllable-timed is attributed to Pike. Recently, two different proposals have been offered for describing the rhythmic structure of languages from acoustic-phonetic measurements. Ramus has suggested a metric based on the proportion of vocalic intervals and the variability ( SD) of consonantal intervals. Grabe has proposed Pairwise Variability Indices (nPVI, rPVI) calculated from the differences in vocalic and consonantal durations between successive syllables. We have calculated both the Ramus and Grabe metrics for Latvian, traditionally considered a syllable rhythm language, and for Latvian as spoken by Russian l…
Acoustic properties and perception of minimal contrasts in Valencian Catalan sibilants
2017
El valencià estàndard presenta tres consonants fricatives sibilants: /s/, /z/ i /S/.Mentre que el contrast entre /z/ i /s/ sembla indiscutible, l’existència d’unaoposició real entre /S/ i /s/ és més dubtosa. El primer objectiu d’aquest treball éscomprovar si, en un estil de parla hiperarticulat (Fonet, Gonzàlvez et al., 2007), laconsonant /s/ és diferent de /z/ i de /S/ tenint en compte set paràmetres acústics:durada, harmonicitat, pic espectral i quatre moments espectrals: centre de gravetat,desviació estàndard, asimetria i curtosi. Les dades revelen que /z/ i /s/ contrastenclarament en durada, harmonicitat i asimetria; /S/ i /s/ contrasten en harmonicitat,desviació estàndard, curtosi i, e…
Idiomatic intonation and forensic phonetics: sociolinguistic and dialectal information from intonation in Spanish
2015
Las investigaciones de carácter geoprosódico realizadas sobre el español y sus variedades ponen en evidencia que la entonación puede reportar importantes beneficios a la fonética forense, ya que esta lleva asociada información de carácter dialectal y sociolingüístico de especial relevancia sobre el individuo –grupo sociocultural al que pertenece, origen geográfico, medio social en el que se inserta–, además de otros rasgos, cualidades o circunstancias como la edad, el sexo, o incluso su temperamento, carácter o estado de ánimo. Para ello se hace necesario no solo saber qué parámetros acústicos suprasegmentales son relevantes para la identificación del hablante, sino también analizar la vari…
O galego-português, matriz do mundo lingüístico luso-brasileiro
2021
O período inicial desta breve história da língua galega e o reintegracionismo lingüístico começa com umhas observaçons de umha «Carta» de Martim Sarmiento (1695-1771), precursor da filologia galega, e finaliza em 2019, ano em que a Real Academia Galega (RAG), toma o acordo de dedicar-lhe o «Dia das Letras Galegas» ao polígrafo ferrolano Ricardo Carvalho Calero (Ferrol 1910 - Santiago de Compostela 1990). Elaboram-se apenas umhas ideias sobre o século XIX e primeira metade do XX; mais informaçom aparece sobre a segunda metade do século passado e primeiras décadas do XXI.
