or he may understand you in another way assuming something different from what is meant Therefore, pronunciation has great influence on the success of oral communication It is said that the better your pronunciation is, the better you will be treated and the more comfortable people will feel when dealing with you At university level, it is really important to have good pronunciation because it helps students to be confident in taking oral exams Certainly, examiners will be impressed with examinees‟ vocal clarity, and students‟ presentation will sound more professional and persuasive to listeners TIEU LUAN MOI download : skknchat@gmail.com These premises have urged me into carrying research into the most common mistakes made by senior non- English major students at Thai Nguyen University of Economics and Business Administration (TUEBA) when pronouncing English final consonants The research ultimately aims at finding out solutions and to help Vietnamese learners of English overcome these mistakes AIMS OF THE RESEARCH Making mistakes in pronouncing final consonants is regarded as very common for students when they learn English These difficulties are challenges for Vietnamese learners in general and for senior year non- English major students in particular if they not find the most suitable study method for themselves In this study, the author investigates the most common mistakes made by those learners to:  Identify the most common mistakes in pronouncing English final consonants: /p/, /b/, /t/, /d/, /k/, and /g/ by senior non-English major students at Thai Nguyen University of Economics and Business Administration;  Find out the causes of these mistakes;  Provide some strategies to help students avoid mispronunciation Hopefully, this research will provide one more reference source for teachers of English as a second language when they teach pronunciation At the same time, this will also be useful to Vietnamese students of English in correcting their mistakes and improving pronunciation skills RESEARCH METHODOLOGY Research questions The study addresses the following four questions: Do Vietnamese learners of English make mistakes when pronouncing English final stop consonants? What are the most common mistakes students often make? What are the causes of the mispronunciation? TIEU LUAN MOI download : skknchat@gmail.com What are the possible solutions to help learners correct these mistakes? Research context The research was conducted on 150 senior English non- major students of joint training program between Thai Nguyen University of Economics and Business Administration and Daegu Cyber University These students had a lot of chances to improve their English proficiency because most of the courses were taught in English Research method The study was conducted via a survey in which two instruments of data collection were used: recording the informants‟ pronunciation of selected isolated words and words within utterances, sentences and texts to find out the common pronunciation mistakes with stop final consonants and a questionnaire to investigate the causes of the mistakes and the solutions to the problems The data analysis is quantitative SCOPE OF THE STUDY The English alphabet is based on Latin and contains twenty six letters However, the English sound system consists of forty four phonemes: twenty four consonants, twelve pure vowels (monothongs), and eight diphthongs In general, Vietnamese learners have difficulties in pronouncing some of the English sounds only but not all of them It is necessary to make a distinction between errors and mistakes According to “Longman Dictionary of Language Teaching & Applied Linguistics” by Richards J, Platt J and Platt H (1992), errors results from incomplete knowledge but mistakes are made when writing or speaking and caused by lack of attention, fatigue, carelessness or some other aspect of performance Due to time constraints, the length of thesis (minor thesis) and the researcher‟s knowledge, it is impossible for the researcher to study all the mistakes made by students when producing English consonants Therefore, this study only focuses on finding out the most typical mistakes made by some senior non-English major students at TUEBA when pronouncing the six English stop consonants /p/, /b/, /t/, /d/, /k/ and /g/ at final position of words with the following reasons: TIEU LUAN MOI download : skknchat@gmail.com  There has not yet been any research on all the six stop consonants Several authors have studied one or two certain consonants of the six only  Six stop consonants are not so difficult to produce, however students seem to omit these sounds at final position Basing on my teaching experience, I find that most students often make mistakes with some plosive consonants like /t/, /d/, /p, /b/ and the most common mistakes are sound omission and sound deviation The said reasons have motivated me to carry out this study to find out the mistakes as well as to offer strategies to help students to overcome this problem DESIGN OF THE STUDY The thesis comprises three parts: The first part is the introduction which includes the rationale, aims, research methodology, scope and design of the study The second part, development, is divided into three chapters Chapter one provides the theoretical background and literature review of the study The theoretical background presents the general description of stop consonants, the phonological characteristics and articulation of the sounds /p/, /b/, /t/, /d/, /k/ and /g/ and a comparison between Vietnamese final consonants and English final consonants The literature review discusses previous works related to consonant pronunciation among second language learners Chapter two is devoted to the methodology of the study in which the research questions are raised, the informants of the study are discussed and the research method is given with the data collection instruments, the data analysis methods and data collection procedure Chapter 3, data analysis: findings and discussion, analyses the data collected from the recordings and the questionnaire and presents the findings and discussion of the study The final part is the conclusion including a summary of the study, concluding remarks, pedagogical implications and suggestions for further research TIEU LUAN MOI download : skknchat@gmail.com PART THREE: CONCLUSION Summary After years teaching English as a foreign language for English non-major students at TUEBA, the researcher finds that almost all of English learners not produce final consonants It can not be denied that proper pronunciation plays a very important role in communication These reasons motivated the researcher to carry out this study It was conducted on 150 senior English non-major students studying at Thai Nguyen University of Economics and Business Administration to identify their common mistakes when they produced English stop consonants at final position In addition, this study discovered the causes of the participants‟ mistakes as well as gave the strategies to help them improve their English pronunciation It can be said that this research is quite a useful reference for those who are interested in teaching English language pronunciation Concluding remarks Doing scientific researches is a requirement and interest of any teachers who dedicate all their lives to their teaching jobs Whenever they carry out a study to improve their language teaching or their own passion, implementing the concluding recommendations is the main purpose The researcher has the same expectation when doing this research, and it is the great success of the writer that all the research questions have been answered Do Vietnamese learners of English make mistakes when pronouncing English final stop consonants? It can be confirmed that Vietnamese learners of English made mistakes when pronouncing English final stop consonants /p/, /b/, /t/, /d/, /k/ and /g/ by looking at the data collected and the analyzed data in the findings of the recorded All of the informants of the study made some or all stop consonants at the final position with different occurrence What are the common mistakes students often make? The second research question of the study concerns clearly what kinds of mistakes students often make by looking the findings of the recordings The most common mistakes that the informants often made were the sound omission and sound deviation The way they produced the studied sounds was different from those described in the 38 TIEU LUAN MOI download : skknchat@gmail.com theoretical background by either omitting them or replacing by a sound similar to it in a certain pair There were the sounds that the subjects did not omit like /p/, /b/ and /g/ or rarely omitted like /k/ However most of informants had difficulty with the sound /t/ and /d/ and they often omitted them in their speech This may be because of some reasons Firstly, these two sounds are more difficult than the others when producing Secondly, it is the habit of the students when they speak English They rarely pay attention to the /t/ and /d/ when they are in the final position and sometimes it is quite hard for them to determine these sounds (For example, the word ending in “ed” is pronounced as /d/ if the sound before it is a voiced sound) Lastly, it is the articulation ability of the speakers The air from the lungs is not strong enough to have an aspirated plosive That is why the listeners find it hard to hear the final sound /t/ and /d/ The second kind of mispronunciation mistake of this research is the sound deviation As mentioned in the chapter of data analysis: findings and discussion, up to nearly 87 % of the students participating in the recordings mispronounced the pair /t/ to /d/, and 100 % of the subjects deviated from /k/ to /g/, /p/ to /b/ or /f/ and vice versa It can be said that students seem not to distinguish the difference between these sounds For example, /k/ is a voiceless sound but they deviate to /g/ with the vibration In addition, within each pair, the way to produce the two sounds is similar in the manner of articulation so sometimes they mispronounce them What are the causes of the mispronunciation? Along with identifying the most common mistakes, it is more important and indispensable to explore the causes leading to these mistakes in producing six stop final consonants by senior English non- major students at TUEBA, school year 2011-2012 Among the causes of mispronunciation, imitating the respondents‟ teachers and friends when they speak English is considered the most prevalent obstacles that 49 % of the respondents agreed upon This means that their pronunciation ability is influenced by the people speaking around them If they speak English correctly, the students will have the correct pronunciation If not, they will have bad or wrong English pronunciation Furthermore, 40 39 TIEU LUAN MOI download : skknchat@gmail.com % of the respondents affirmed that they did not know how to produce these stop sounds This may be because that they not have many chances to learn English phonetics and phonology in class or practise English pronunciation at home Another cause that prevented students from speaking English correctly was that they thought that they could not pronounce these stop sounds accurately It can be inferred that they are pessimistic about obtaining English proficiency This reason is really serious as they would make students become passive learners On the other hand, there are some other important subjective causes that lead to informants‟ mispronunciations For example, they were afraid of asking their teachers or friends for help (29 % agreed) or did not practise pronunciation frequently (40 % agreed) as well as did not pay attention to the pronunciation of these sounds at final position (36 % agreed) There are also two wrong opinions of the respondents on the pronunciation that add to their mistakes The fist one is that they thought that English sounds and Vietnamese sounds have the same way of production (30 % agreed) The last one is the opinion that they did not think bad or wrong pronunciation can cause communication breakdown (37 % agreed) This explains why they often make mistakes when speaking English What are the possible solutions to help learners correct their mistakes? The subjects were asked about how often they applied the given strategies to improve their pronunciation Imitating the native speakers speaking English is the method that 35 % of the respondents often used and 36 % of them sometimes used As mentioned in the methodology chapter, the informants had a lot of chances to learn English as well as other subjects with native speakers as the program they were following was the joint training between TUEBA and the foreign partner In addition, practicing speaking as much as possible was used by 48 % of informants They sometimes applied this method to help them speak English better They often asked English teachers and friends for help (31 %) and attended English pronunciation courses (32 %) to have better pronunciation In addition to the students‟ ways of learning, the teachers‟ methods of teaching play a very important role in the learners‟ speaking 50 % of the asked respondents agreed that sometimes their teachers gave explicit meta-linguistic instruction in English phonetics and 40 TIEU LUAN MOI download : skknchat@gmail.com phonology and 45 % of them affirmed that the teachers often applied the method of listening and repeating This method helps students remember the pronunciation of the words better In addition, tongue twisters and minimal pair drills were sometimes used by their teachers (49 % and 38 % agreed on these methods) Besides, recording the subjects‟ speaking was another way that could often be used by the teachers Pedagogical Implications Learning a foreign language is a long term process which requires a lot of learners‟ effort to be successful Oral communication needs correct pronunciation Learners may encounter a lot of challenges when they learn how to pronounce properly For Vietnamese learners in general and TUEBA students in particular, it is common to see that students often make pronunciation mistakes when they produce English final consonant sounds Therefore, the teachers of English should make students aware of the importance of correct pronunciation in practice so that they would spend more time on pronunciation In designing and selecting materials for teaching it is necessary to consider the purpose of the learners‟ language study, whether it is to acquire a native like accent or for intelligibility in international communication This study can be used as a useful teaching material as it provides the basic knowledge of pronunciation It is also a source of visual aids to demonstrate the ways some sounds are produced with clear and exact demonstration To improve TUEBA learners‟ pronunciation of English consonant in word final position, first of all, the teachers should help them be aware of the significance of final sounds In order to minimize the language interference, it is necessary for teachers to provide learners with detailed description of consonant sounds such as their manner and place of articulation, the variants of each phoneme Besides, Vietnamese special features should be taken into account The limitation of phonetic knowledge happens maybe owing to the carelessness of the learners or the teaching induced errors Therefore, firstly teachers must teach correct pronunciation Secondly, it is essential to teach students theoretical matters related to pronunciation At the same time, teachers should ask the students to practice them in 41 TIEU LUAN MOI download : skknchat@gmail.com isolating words as well as in connected speech More importantly they should get students involved in learning how to produce words correctly and practice as often as possible Limitations and Suggestions for further research Although this study has answered the research questions relating to TUEBA students‟ mispronunciation of English final stop consonants, it still has some limitations As the time used for doing this thesis is limited, the researcher only focused on the most common mistakes when students pronounced six English stop consonants in word final position The combination of these sounds with other sounds is not typical enough to find out various problems such as consonant clusters, linkage of sounds and so on Secondly, natural speech was not recorded for the study but the required recording was and the researcher did not have time to conduct the interview to have more and deeper information about their difficulty that caused their mistakes In addition, as the sounds were recorded with informants‟ consciousness, there may be some unavoidable factors such as anxiety and nervousness Consequently, the recorded sounds were not as closed to their natural speaking In order to get a good pronunciation, learners should pay attention to not only English sounds but also stress, intonation, rhythm etc as well This means that to have a full picture of Vietnamese learners‟ pronunciation, much more researches should be conducted However, it can not be denied that this study has placed the first brick to this issue and this will become a hot topic in the teaching and learning forums The researcher does hope that in the future, she can have more opportunities to further study to go to deeper into this field The researcher would be grateful to receive all remarks, comments, and suggestions from the readers so that her next research will be better 42 TIEU LUAN MOI download : skknchat@gmail.com
