The Language Technologies Institute, a world leader in the areas of speech processing, language processing, information retrieval, machine translation, machine learning, and computational biology, offers a two-year Masters in Language Technologies (MLT) degree. The MLT program consists of courses (including lectures, labs and seminars), as well as directed research and project work. Most MLT students are affiliated with an advisor's research project, in which they gain hands-on experience with advanced research and state-of-the-art software. An optional master's thesis project may also be chosen.

The MLT program is a research-oriented degree. Many of our students publish papers at top international conferences in their field, and many of our graduates continue on to PhD programs at the LTI or other top universities. When MLT graduates are admitted to the LTI PhD program, most of their MLT courses and hands-on work are credited toward the PhD The MLT program is also appropriate for students who want to gain experience for industry jobs in the increasingly important fields of speech processing, information retrieval, language processing, machine translation, and computational biology. MLT graduates are highly recruited by industry and the government.

Program Description

The MLT program lasts two years (24 months), and students are required to complete two summers of research during this time. Students should normally expect to graduate in August of the second year.

The MLT curriculum consists of 120 or more course units, at least 72 of which are LTI courses, and 24 of which are SCS courses. Most of these are 12-unit courses, although lab courses are typically 6 units. Our courses generally assume knowledge of programming and data structures. All students have a faculty advisor with whom to discuss and agree upon the actual set of courses to be taken, subject to the above constraints and consistent with the student's area of specialization. Directed research is another integral part of the MLT program; MLT students carry out directed research during the course of their studies, with guidance from their faculty advisors. Most LTI courses are offered once a year, although some courses are taught every other year.

After 96 units are selected, the remaining units may also be taken from the LTI , or with approval of the faculty advisor, from any other senior- or graduate-level course offered at CMU or Pitt. Up to 12 of these additional units can be in the form of directed study. Depending on a student's interests, electives may be taken from the LTI, other SCS departments, or other CMU or Pitt departments. Students interested in speech should consider speech-oriented electives. Other areas of interest include linguistics, statistics, and human-computer interaction (HCI).
