Laboratories


Computational Linguistics Lab

  • Director: Jeffrey Heinz
  • Research in the Computational Linguistics Lab is concerned with the analysis of natural language phenomena using tools and concepts from mathematics and computer science, in particular statistics and probability theory, formal language theory, machine learning, algebra and logic. The lab suite includes a class room, workstations, a library, and access to a large number of corpora and software.

Laboratory for the Phonetic Documentation of Languages

  • Director: José Elías-Ulloa
  • The Laboratory for the Phonetic Documentation of Languages’ mission is to provide equipment and training to carry out phonetic and phonological documentation of languages in the field. The lab has already been used to document acoustically an Amazonian language (Shipibo-Konibo - Pano) and it is currently being used in the documentation of the intonational patterns of Peruvian and Colombian Spanish. It houses equipment for high quality audio recording in the field (this includes a Marantz solid state digital recorder, several Zoom H4 and H4n digital recorders, omni- and uni- directional XLR SHURE microphones and pre-amps). The lab also has a RAID server for data storage and equipment for carrying out electroglottography (EGG) and measurements of oral/nasal airflow.

Phonetics Lab

  • Director: Marie Huffman
  • The phonetics lab provides equipment for investigation of a wide range of linguistic questions, with special emphasis on speech acoustics, dialogue, and speech perception. The lab suite includes a lab classroom, a recording room and a research annex, with digital tape recorders, microphones, and headphones as well as equipment setups that allow for onscreen cueing and data acquisition as well as various methods of recording multi-person conversation and video recording of spoken or signed language.

Semantics Lab

  • Director: Richard Larson
  • The semantics Lab was created in 1992 by Richard K. Larson (Linguistics) and David S. Warren (Computer Science) as part of the NSF-sponsored Grammar as Science Project. Along with primary research in semantics, a focus of the lab has been the creation of software tools for linguistics research and education.  Productions to date include Syntactica, a program for teaching transformational syntax and Semantica, a companion program for teaching truth-conditional natural language semantics.  At present we are authoring a web-based application to assist students in developing basic parsing skills with phrase structure trees.  This work is part of a new departmental hybrid on-line course The Anatomy of English (developed in collaboration with M. Aronoff and M. Lindsay).
