The main purpose of this study was to identify intonational patterns of a quite common type of numeric grouping in Brazilian Portuguese: the one associated with telephone numbers. To this aim, 30 samples of spoken telephone numbers, read aloud by 85 native speakers of Brazilian Portuguese were analysed. The description of their intonation contour was observed by using Momel/Intsint [1] and ProsodyPro [2] scripts for Praat (version 5.3.53) [3], through a semi-automatic analysis of pitch variations in numeric groupings that form the telephone numbers. The results show a pattern of intonation and numeric grouping strategy that are sufficient enough to prosodically characterize different types of spoken telephone numbers in Brazilian Portuguese.
