“…As synthetic speech more closely approximates human voices, there is a tendency to use synthetic speech in tutoring systems (Song et al 2004) and TTS systems have been integrated into many electronic language dictionaries. On the other hand, in comparison with the flexibility of using synthetic speech, the superior quality of pre-recorded audio is preferred by CALL systems (Morton and Jack 2005).…”

Can synthetic speech be utilized in foreign language learning as natural speech? In this paper, we evaluated synthetic speech from the viewpoint of learners in order to find out an answer. The results pointed out that learners do not recognize remarkable differences between synthetic voices and natural voices for the words with short vowels and long vowels when they try to understand the meanings of the sounds. The data explicates that synthetic voice utterances of sentences are easier to understand and more acceptable by learners compared to synthetic voice utterances of words. In addition, the ratings on both synthetic voices and natural voices strongly depend upon the learners' listening comprehension abilities. We conclude that some synthetic speech with specific pronunciations of vowels may be suitable for listening materials and suggest that evaluating TTS systems by comparing synthetic speech with natural speech and building a lexical database of synthetic speech that closely approximates natural speech will be helpful for teachers to readily use many existing CALL tools.

Inquiry teaching plays an important role for innovative personnel training. With the development of network technology, web-based teaching mode becomes a mainstream education form. This paper presents a teaching mode combining classroom teaching and online teaching mode from an angle of cultivating innovative personnel. And then shows the curriculum resources needed for network learning. A framework of a network teaching platform which can manage curriculum resources and provide online learning is presented. Finally a case is studied and the experience of curriculum reform and construction is shared.

“…Universities, professional development centres, and industry training facilities worldwide are now offering thousands of technical and management courses. Now, the development of web-based learning environments has over the last few years constituted a domain trend in technology-enhanced education (Choi, 1999;Khalifa & Lam, 2002;Pahl, 2003;Song, Hu, Olney, & Graesser, 2004). The broad application of the Internet in e-Learning has led to a common requirement for reusable, sharable learning objects.…”
