In this study, data on the phonetic and diatopic variation of /b/ phoneme produced by Chilean professionals is presented. The results showed five variants of /b/, although only three were statistically significant: [b], [β] y [[white square]]. Of these three, the plosive variant [b]was the most stable. The bilabial approximant [βT] predominates across the country followed by the labiodental approximant [[white square]]. These results also suggest a dialectal variation of the labiodentalism between northen and center areas, and between southern and southernmost zones.
