Dr Le Hoang Dung who carefully helped shape my ideas and painstakingly read my research proposal which paid tribute to the foundation of my thesis I would like to sincerely thank M.A David Mac Grath Hardy from University of Houston- USA and his parents for helping me with the standard recordings which were the main criteria for the data analysis in both recording tests I should wholeheartedly thank Dr Pascal Van Lieshout from University of TorontoCanada who generously provided me with many useful materials related to Praat I also appreciated the insights shared by M.A Dang Hoai Phuong, M.A Hoang Thi Nhat Tam, and M.A Bui Huynh Thuy Thuong who have deepened my understanding of the suprasegmental features in English phonology I gratefully acknowledge the help of Ms Hoang To Uyen and Ms Huynh Ho Tuong Van – the librarians at the ERC, who kindly provided me with many valuable works of reference related to the topic of my study My ultimate gratitude is reserved for the participants of the study, the UPS’s non-English majors, who were willing to take part in the two recording tests as well as the training in Praat with their great patience and cooperation Last but not least, while trying to write this thesis, I am, as always, indebted to my parents, who are always beside me and encourage me to complete the thesis Without their support, I could not have finished my thesis iv ABSTRACT The wave of the globalization has not only changed materials for EFL teaching in general but also reinforced a new notion of English pronunciation whose focus is on the intelligibility in particular With an urgent demand for the innovative teaching of English, this study has been conducted with a focus on the application of speech analysis software tool to identify and improve English rhythmic errors because the English rhythm is one of the decisive factors influencing on EFL learners’ acquisition of the intelligibility in speaking English Its experimental research design enables the researcher to apply Praat, a speech analysis software tool, in achieving the study’s objectives Eventually, the findings of the study provide a corroboration for the hypotheses proposed in the study The two major types of rhythm errors of which the researcher suggests taking notice, namely, the segmentation of thought groups in an utterance and the stress of content words and function words in an utterance Hence, the application of Praat puts forward some constructive ideas for helping non-English majors deal with the English rhythm – one of the important aspects of connected speech that are indispensable factors of an intelligible pronunciation; moreover, the study introduces a new approach in teaching English pronunciation in general and the English rhythm in particular to non-English majors who are usually afraid of speaking English v TABLE OF CONTENTS PAGE Statement of originality i Retention and use of the thesis ii Approval sheet iii Acknowledgements iv Abstract v

Respondents, After practising Praat on the English rhythm, you are supposed to have an experience of identifying and improving your rhythmic errors when speaking English with the help of this speech analysis software De facto, the learner’s perspectives on the use of Praat may be different from those researchers and teachers Therefore, you are requested to spend some time reflecting on what you
