EA contains a fresh take on phonological inventories from Eurasia. The data were extracted from grammatical descriptions of individual language varieties. It contains only phonemes, with no information on allophones or linguistic tone.

The data are available in phoible long format in EA_inventories.tsv. We have converted IPA symbols in the raw data in line with the phoible conventions and Unicode IPA as specified in the EA_IPA_correspondences.tsv correspondences file. We have also collected for each citation a BibTeX reference, available in the phoible-references.bib file.

Note that the ISO 639-3 codes in the EA source may be out of date with the current ISO 639-3 standard. For more info, see: https://iso639-3.sil.org/.

For up-to-date language codes for each inventory, we maintain a phoible index here: InventoryID-LanguageCodes.tsv.
