1.1 Rationale of the study
Nowadays, with the rapid pace of integration and globalization, English becomes a golden key to open the door of many fields such as commerce, communication, science and technology throughout the world. Therefore, to meet the demand of the society, it is very necessary to teach English in schools at all levels. And the highest target is to get well in communication. If one wants to get successful in communication, he must be good at pronunciation: “a threshold level of pronunciation in English such that if a given non-native speaker 's pronunciation falls below this level, he or she will not be able to communicate orally no matter how good his or her control of English grammar and vocabulary might be” (Celce-Murcia, 1987:5).
In the field of language teaching, the role of pronunciation has varied widely from having virtually no role in the grammar-translation method to being the central focus in the audio-lingual method where emphasis is on the traditional notions of pronunciation, minimal pairs, drills and short conversations. The growing emphasis on communicative approaches for the teaching of English has placed higher demands for correct pronunciation. Despite this fact, at the upper-secondary school level in Vietnam, in language teaching and learning, compared with vocabulary, grammar and language skills, pronunciation has so far been paid less attention to. In the official textbooks used for teaching English at high school level, there are a few exercises for pronunciation practice. To make the matter worse, all important English exams at schools as well as the entrance exam to universities are always in written form so most teachers as well as students have little motivation to teach and to learn pronunciation. As a result, students are often shy and unconfident to speak in English. And that is the reason why the effectiveness of teaching pronunciation still remains one of the most widely problematic
