11. Summary of new results of the thesis:
The thesis used the experimental phonetic research method with a relatively large number of participants who had high English proficiency; from which the following results were obtained:
- For single words, the group of initial three-syllable consonant clusters is the group with the lowest standard deviation; meanwhile, the group of final four-syllable consonant clusters is the group with the highest standard deviation. Similar results also appear for the pronunciation of consonant clusters in the flow, however, with the pronunciation in the flow, the standard deviation of each case of the cluster is higher than that of the pronunciation of single words.
- Syllable-initial and syllable-final combinations have quite similar standard deviation rates, in which the 3-consonant and 4-consonant final syllable combinations have much higher standard deviation rates than the remaining groups.
- Among the 4 groups of participants, group 4 (the group of participants who studied domestically and spent a lot of time using English) had the highest rate of pronunciation closest to native speakers, and group 3 (the group of participants who studied abroad and spent little time using English) had the highest rate of pronunciation deviation.
- With consonant combinations in the initial position of syllables, in the 4 groups of Vietnamese test takers, the duration of the English consonant combination pronunciation of the group of Vietnamese people studying in the country and having a lot of time using English (group 4) is the group with the highest rate of near-standard in terms of duration, followed by the group of Vietnamese people studying abroad and having a lot of time using English (group 2). Group 3 and group 5 are test takers who have less time using English and both have higher standard deviation rates than the two groups above. Intensity does not have much of a definite value. Some common variations include: consonant substitution, vowel addition, consonant addition, and consonant reduction.
- For consonant clusters in syllable-final position, all groups of Vietnamese speakers tend to pronounce syllable-final consonant clusters longer than native speakers. The standard deviation rate in the group of participants who studied in the country and used English for a long time is still the lowest compared to the other three groups. Intensity does not have much of a determinative value. Some common variations include: consonant reduction, consonant substitution, and inversion of cluster order.
12. Practical application:
The research results of the thesis will contribute positively to the teaching and compilation of English teaching materials for Vietnamese people. At the same time, the results of the thesis can also be useful references for building the characteristics of English use of Vietnamese people, or for the work of comparing Vietnamese with other languages...
13. Further research directions:
The thesis limits the scope of research to the pronunciation of English consonant combinations in Vietnamese English speakers and stops at four groups of participants. Research and survey of other aspects of phonetics such as vowel pronunciation, stress, etc. will open up new research directions in other research projects.

11. Summary of the new findings of the thesis:
The thesis has applied the instrumental phonetic method with a remarkable number of informants who are at advanced level of English, and has come up with the following results:
- For isolated words, the three-consonant clusters are the group with the lowest standard deviation ratio. Meanwhile, the four-consonant clusters are the group with the highest standard deviation ratio. Similar results appear with the pronunciation of consonant clusters in utterances, but the standard deviation rate for those in utterances is higher than that of isolated words.
- Both initial and ending consonant clusters have similar standard deviation rates, in which the combination of 3 consonant clusters and 4-consonant ending clusters are the cases that have a much higher standard deviation rate than other groups.
- Among the four informant groups, group 4 (the group of studying learners in Vietnam and having much time using English in their job) is the group with the pronunciation ratio being closest to that of native speakers, and group 3 (the group of learners studying in foreign countries and have limited English use time) is the group with the highest standard deviation rate.
- With the case of consonant clusters at the beginning of syllables, among 4 Vietnamese informants groups, the group whose members studied in Vietnam and had time to use English much (group 4) is the group with the highest quasi-standard ratio in terms of duration, followed by the group of Vietnamese who study abroad and have a lot of time using English (group 2). Group 3 and group 5 are the informants who have little time to use English and have a higher standard deviation than the two groups above. Intensity does not have much defined value. Some common variations include: replacing consonants, adding vowels, adding consonants, and simplifying consonants.
- With the case of consonant clusters at the end of syllables, all groups of Vietnamese informants tend to pronounce the consonant clusters at the end of syllables longer than native speakers. The standard deviation rate for the group who studied in Vietnam and used English for a long time was still the lowest compared to the other three groups. Intensity does not have much defined value. Some common variations include: simplifying consonants, replacing consonants, and reversing consonants (changing their order) in clusters.
12. Practical applicability, if any:
The results of the thesis will contribute positively to the teaching as well as the development of English teaching materials for Vietnamese. At the same time, the results of the thesis may also be useful references for figuring out a branch of Vietnamese English, or comparing Vietnamese and other languages.
13. Further research direction, if any:
The thesis limits the scope of the study as the features of consonant pronunciation clusters only and resulting in four groups of participants. The study on other fields of phonetics and phonology, such as vowel pronunciation, word stress sentence stress, etc., will open new research directions in other studies.
