ABSTRACT During the last few decades, the size of databases containing data about prosodic diatopic variation has increased dramatically. For this reason, researchers need adequate statistical methods and tools to cope with such huge amount of information. This paper aims at describing Calcu-Dista, a tool whose aim is carrying out a dialectometric analysis of acoustic intonational data within the framework of the AMPER project. In addition to describing how Calcu-Dista works, this paper provides validation of its results.
