Linguistic Atlas Project
The Linguistic Atlas Project (LAP) is a linguistic research initiative that documents dialectal variation in American English. The LAP conducts regional dialect surveys using structured interviews to produce linguistic atlases. It was founded by the American Dialect Society in 1929 and initially directed by Hans Kurath. The LAP consists of multiple regional sub-projects that examine variation in vocabulary, pronunciation, and grammar to identify historical settlement patterns and cultural influences.
More than 5,000 face-to-face dialect interviews have been conducted across the United States. The project includes more than 8,500 hours of audio recordings, which are accessible through online interfaces and public repositories.
Over its history, the LAP has been housed at multiple institutions. It was based at the University of Georgia for more than 25 years, and since 2018 has been housed at the University of Kentucky under the direction of Allison Burkette, where it is undergoing digitization to make materials publicly available for research.
