Does Text-to-speech Synthesis Fit the EFL Learners’ Needs in EIL Context?

Abstract

The present study attempts to evaluate a TTS synthesis system from the perspective of EIL. 100 pre-service teachers are selected to evaluate speech produced by a TTS synthesis system with the respect of intelligibility, naturalness, prosody, and social impression. A questionnaire adopting the MOS X is developed to evaluate speech in three experiments.
