PHOIBLE is a database of phonological inventories and distinctive features, encompassing more than 1600 languages (and growing). PHOIBLE data is published in browsable form online at PHOIBLE Online, which corresponds with the most recent year-numbered 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 dated 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 root of this repository, which contains a phoneme-level data file (one row per language-phoneme pair), a language-level data file (one row per language, with various language-level aggregations like “total consonants” or “total segments”), and a BibTeX file of all the data sources. The
code directory 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
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 root directory.
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:

If you are using the raw data from this repository but are not using a labeled release, we recommend citing using the last commit hash at the time of your most recent cloning/forking of the repository, so that others can reproduce your work starting from the same snapshot of the repository that you are using.

PHOIBLE was originally developed as an SQL database and RDF knowledgebase for Moran’s dissertation, which explains many of the technical details and developmental challenges:
