PHOIBLE is a database of phonological inventories and distinctive features, encompassing more than 3000 phonological inventories (doculects), representing more than 2100 ISO 639-3 language codes. PHOIBLE data is published in browsable form online at PHOIBLE Online, which corresponds with the most recent release of this repository.
Data in machine-readable form is available in this repository. It is not guaranteed to exactly match what is published at PHOIBLE Online, due to the occasional discovery and correction of errors, and the addition of new languages to the database. For this reason, it is recommended that you make use of the most recent release in your own analyses, rather than working from the tip of the master branch.
Documentation for PHOIBLE is hosted at at http://phoible.github.io/, including notational conventions, departures from official IPA usage, citation information, etc.
How to use this repository
Most people will not need to look beyond the data
folder of this repository,
which contains a phoneme-level data file (one row per languoid-phoneme pair)
and a BibTeX file
of all the data sources. The rest of the repo contains scripts used in the
development and testing of PHOIBLE, such as code to aggregate the raw data
files from the various donor databases. These are probably not of general
interest or utility. The
raw-data directory contains the raw data from the
various donor data sources, as well as the feature mapping tables. This is
also probably not what you want, so if in doubt, stick to the
If you are citing the database as a whole, or making use of the phonological distinctive feature systems in PHOIBLE, please cite as follows:

If you are citing phoneme inventory data for a particular language or languages, please use the name of the language as the title, and include the original data source as an element within PHOIBLE. For example:
