The potential application of artificial intelligence (AI) to computer-assisted language learning (CALL) is explored. Two areas of AI that hold particular interest to those who deal with language meaning--knowledge representation and expert systems, and natural-language processing--are described and examples of each are presented. AI contribution to computers and natural language in such areas as understanding natural language, mechanical parsing, machine translation, speech recognition, and speech synthesis are outlined. Examples of CALL programs using AI are presented, including ELIZA, SHRDLU, LIESL, FAMILIA, JOHN AND MARY, JUEGOS COMUNICATIVOS, and STATION. Current major projects using AI in CALL are also described, including Project Athena, at the Massachusetts Institute of Technology; TALK (Teacher's Authoring Language Kit) Project, at the University of Rochester in New York; Project Alexis, at Mills College in California; and Intelligent Grammar Tutor, at the University of Pittsburgh in Pennsylvania.
