PHOnetics Information Base and LExicon
Introduction and Rationale
Linguistics is a discipline that is reaping large advances from computational methods, computer processing and statistical models.
Although numerous individual languages' phonologies and phonetics have been described, the majority still reside in widely
inaccessible formats, including paper, proprietary software programs, antique hardware, or inoperable encodings. To date there is
no central repository for the sounds from all known languages that includes theoretical models of distinctive feature sets.
Here, we are developing the Phonetics Information Base and Lexicon (PHOIBLE), a typological phonological database to encompass
the feature sets and sound systems from all known languages for which resources can be discovered.
The current database includes
200 languages' phonemic and corresponding allophonic inventories from the Stanford Phonology Archive (Crothers et al, 1979),
451 languages' phonemic inventories from UPSID (Maddieson 1984, Maddieson & Precoda 1990),
200 African languages' phonemic and corresponding graphemic inventories (Hartell 1993, Chanard 2006)
and hundreds of other inventories, including descriptions of phonemes, allophones and their conditioning environments,
which we extracted from secondary resources like grammars and phonological descriptions.
The data set also includes additional genealogical and geographical information about each language.
The PHOIBLE project also integrates the theoretical model of distinctive features from an extended phonological feature set
based on International Phonetic Alphabet (IPA; International Phonetic Association 2005) and on Hayes 2009. This is accomplished
by creating a mapping relationship from each IPA segment to a set of features (Moran 2012). In this way, the IPA is a pivot for
interoperability across all resources in PHOIBLE because their contents are encoded in Unicode IPA.

PHOIBLE was funded in 2009 by a grant from the Royalty Research Fund at the University of Washington. The data are available
in several formats for research purposes only. For commercial use,
