Acoustic-phonetic description of the sixth vowel of the spoken chedungun in Alto Bío-Bío

Abstract

This study presents the main results obtained from a phonetic-acoustic analysis of formants 1 and 2 (F1 & F2) of the tonic production of the sixth vowel from chedungun, a dialect of mapudungun, in two locations of Alto Bío-Bío (Queuco and Bío-Bío). These sounds were produced by 10 male speakers from a corpus of more than 100 lexical items specially selected to examine the chedungun phonetic-phonologic system. The data and results on this study indicate by one hand that there is not a significant geographical influence in the production of [ə] and [ɯ], and also that most of the phonetic production were performed as [ə] instead of [ɯ].
