ABSTRACT
In this chapter we are concerned with the use of text-to-speech synthesis, or TTS, as a tool for second language learning. We present a number of language learning applications in which TTS plays a fundamental role. TTS can be used to foster awareness of the contrastive features of the phonology of the second language. It can be used to power a speaking tutor for any selfinstructional system and to voice feedback on an exercise. It can be used as a reader for dictation exercises where the goal is to vary voice quality and speaking rate. TTS can also be used to give students hints about a listening comprehension task and other drills.
