What is SLAAP?

The Sociolinguistic Archive and Analysis Project, at North Carolina State University, is an interactive web-based archive of sociolinguistic recordings, with integrated media playing and annotation features, as well as phonetic analysis and corpus analysis tools designed for enabling and improving empirical linguistic inquiry.

The archive is constantly growing, but currently contains (as of October 2019)

  • over 4,800 interviews;
  • over 7,800 audio files;
  • over 4,000 hours of audio!;

  • over 230 hours of transcribed audio;
  • over 2.3 million words of orthographically transcribed speech, accurately time-stamped and linked to the audio
from a variety of languages (predominately American dialects in North Carolina and the southeastern United States).

Many of the collections housed in SLAAP are indexed in the language resource catalog maintained by OLAC. To find information about many of the collections in SLAAP, you can view SLAAP's entries in the OLAC catalog here and SLAAP's main entry at OLAC here. (This work is ongoing - eventually about 50 collections will be listed in OLAC.)

More information is available by following the links on the left, in particular the F. A. Q. page. Kendall 2007a also provides a good general introduction to SLAAP.
