THE PSYCHOLOGY AND TECHNOLOGY OF TALKING HEADS: APPLICATIONS IN LANGUAGE LEARNING

摘要

Given the value of visible speech, our persistent goal has been to develop, evaluate, and apply animated agents to produce accurate visible speech. The goal of our recent research has been to increase the number of agents and to improve the accuracy of visible speech. Perceptual tests indicted positive results of this work. Given this technology and the framework of the fuzzy logical model of perception (FLMP), we have developed computer-assisted speech and language tutors for deaf, hard of hearing, and autistic children. Baldi, as the conversational agent, guides students through a variety of exercises designed to teach vocabulary and grammar, to improve speech articulation, and to develop linguistic and phonological awareness. The results indicate that the psychology and technology of Baldi holds great promise in language learning and speech therapy.
