Research Abstract

hrough a series of empirical studies, the present project proposed a model that quantitatively estimates human evaluation of given speech data regarding naturalness or fluency. This model made possible the objective evaluation of a non-native accented voice. These results can contribute to the promotion of effectiveness of so-called computer-assisted language learning/testing framework by providing an element of automatic fluency evaluation.
