Review of the application of intelligent speech technology in education

Abstract

Education is the main application field of intelligent speech technology, including automatic speech recognition and speech assessment. In this paper, we introduce some popular application cases of intelligent speech technology in education, such as intelligent micro-lessons, online distance learning and spoken English learning and testing. With the help of intelligent speech technology, people can acquire knowledge faster, learn languages more efficiently, and even communicate by using different languages. Moreover, we propose three kinds of challenging problems in the application of intelligent speech technology, including the recognition of domain-related terms, the recognition of code-switching and the fine-grained mispronunciation diagnosis. Viable state-of-art solutions to these problems are also discussed in detail. Meanwhile, we also discuss what language teachers and researchers can do in solving the above technical problems.
