Abstract
Neste traballo preséntase unha ferramenta informática, desenvolvida co software
estatístico R, que lle permite ao usuario realizar unha análise dialectométrica dos
datos prosódicos do corpus fixo recollido no proxecto AMPER. Non se precisa
coñecementos previos no uso do software R, polo que a ferramenta pode ser
empregada por calquera usuario interesado neste tipo estudos. A análise dialectométrica realizada pola ferramenta inclúe o cálculo de correlacións entre curvas de
F0 e a obtención das distancias prosódicas entre as distintas localizacións (falantes
ou outra variable de interese) existentes no corpus. Unha vez construída a táboa de
distancias prosódicas, o usuario pode aplicar mediante a ferramenta técnicas da
estatística multivariante, como o escalado multidimensional (MDS) e a análise de
conglomerados. Con esta última metodoloxía, o usuario pode detectar
agrupamentos nas localizacións (falantes ou outra variable de interese) segundo a
súa proximidade en termos de distancia prosódica
This paper presents a computing tool, developed with the statistical software R, which allows a user to perform a dialectometric analysis of the prosodic data in the fixed corpus collected in the AMPER project. Since no previous knowledge about using R is assumed, this tool can be used by any user interested in such studies. The dialectometric analysis that is performed includes calculation of correlations between F0 curves and of prosodic distances between different locations covered by the corpus (for speakers or any other variable). Once the table of prosodic distances has been generated, the user can then apply multivariate statistical techniques to it, such as multidimensional scaling (MDS) and cluster analysis. The latter allows the user to detect the existence of clusters of locations (by speaker or another variables) according to their closeness in terms of prosodic distance
