The Language Index

The Place for Learning about the Languages of the World

History

The Language Index, until 2012 part of the Virtual Linguistics Campus, is the most extensive interactive and multimedial collection of languages and language data. All entries are supported by a standardized set of audio recordings. Thus, the information that can be retrieved interactively is more complex but exhibits more linguistic details than elsewhere. Currently, the Language Index hosts 1039 entries and comprises a multitude of linguistic options, from simple language lookup to detailed sound comparison. All entries can be accessed via the following interfaces:

  • The (main) Language Map
  • The Language List
  • The Map of Typological Parameters
  • The Map allowing Cognate Comparison

The idea of using audio data for the representation of languages was born in 1996, when J. Handke and F. Intemann published their CD-ROM "The Interactive Introduction to Linguistics". Even though the CD contained a mere 25 languages, it became the starting point for today's largest interactive structured audio database. The following table lists the milestones in the development of the VLC Language Index including the experience gained from the CD-ROMs that the LET developed for W. Labov's Atlas of North American English and Kortmann/Schneider's A Handbook of Varieties of English.
