[1][2] Additionally, Hmong–Mien languages are included by some linguists, and even Japanese was speculated to be Austric in an early version of the hypothesis by Paul K.

He showed phonological, morphological, and lexical evidence to support the existence of an Austric phylum consisting of Austroasiatic and Austronesian.

[18] In the second half of the last century, Paul K. Benedict raised a vocal critique of the Austric proposal, eventually calling it an 'extinct' proto-language.

[19][16] Hayes' lexical comparisons, which were presented as supporting evidence for Austric between 1992 and 2001, were criticized for the greater part as methodologically unsound by several reviewers.

[23] Note however that ASJP is not widely accepted among historical linguists as an adequate method to establish or evaluate relationships between language families.
