Linguistic corpora

Jointly with the NU Library and related departments, the Linguistics Department holds a membership in the Linguistic Data Consortium (LDC), which provides access to a wide variety of text and speech corpora in many languages. In addition, a number of proprietary and specially licensed corpora are in use for research purposes. For instructions on accessing and using currently installed corpora, or for questions about obtaining corpora, follow this link.

Software

A variety of software for the analysis of spoken and written texts is available in the department's research labs. This includes Praat, a program for speech analysis and synthesis; a variety of part-of-speech taggers, morphological analyzers, parsers, and programs for the statistical analysis of written texts; site-licensed packages for large-scale modeling, visualization and numerical analysis, such as Mathematica, Matlab, SAS and SPSS. The use of these computational tools in student work is strongly encouraged at Northwestern.

In addition to these externally-developed packages, several software applications for audio processing and experimental design have been developed at Northwestern. For more information please see Chun Chan's website.
