Speech technology in computer-aided language learning: Strengths and limitations of a new CALL paradigm
Farzad Ehsani, Eva Knodt · Language learning & technology · 1998
: We investigate the suitability of deploying speech technology in computer-based systems that can be used to teach foreign language skills. In reviewing the current state of speech recognition and speech processing technology and by examining a number of voice-interactive CALL applications, we suggest how to create robust interactive learning environments that exploit the strengths of speech technology while working around its limitations. In conclusion, we will draw on our review of these applications to identify directions of future research that might improve both the design and the overall performance of voice-interactive CALL systems. 1.0 Introduction During the past two decades, the exercise of spoken language skills has received increasing attention among educators. Foreign language curricula focus on productive skills with special emphasis on communicative competence. Students' ability to engage in meaningful conversational interaction in the target language is considered an ...
