Some dialects of Southern Bikol have the close central unrounded vowel /ɨ/ as a reflex of Proto-Austronesian *e. However, Proto-Austronesian *e is realized as /o/ in Libon. Two Bikol dialects have unique additional consonants, namely Southern Catanduanes, which has an interdental lateral consonant /l̟/ (also transcribed as l̪͆ ), and Buhi-non, which has the voiced velar fricative /ɣ/.
