Welcome to PHOIBLE Online

PHOIBLE Online is a repository of cross-linguistic phonological inventory data, which have been extracted from source documents and tertiary databases and compiled into a single searchable convenience sample. There are currently 1240 inventories that contain 1680 segment types found in 1010 distinct languages.

References are provided for each source; note that some languages in PHOIBLE have multiple entries based on distinct sources that disagree about the number and/or identity of that language’s phonemes.

Two principles guide the development of PHOIBLE, though it has proved challenging both theoretically and technologically to abide by them:

  1. Be faithful to the language description in the source document (now often called ‘doculect’, for reasons indicated above)
  2. Encode all character data in a consistent representation in Unicode IPA

In addition to phoneme inventories, PHOIBLE includes distinctive feature data for every phoneme in every language. The feature system used was created by the PHOIBLE developers to be descriptively adequate cross-linguistically. In other words, if two phonemes differ in their graphemic representation, then they necessarily differ in their featural representation as well (regardless of whether those two phonemes coexist in any known doculect). The feature system is loosely based on the feature system in Hayes 2009 with some additions drawn from Moisik & Esling 2011.

However, the final feature system goes beyond both of these sources, and is potentially subject to change as new languages are added to PHOIBLE.
