11. Summary of new results of the thesis:
The study of “The Vietnamese Phonetic System of Overseas Vietnamese in Mukdahan, Thailand” is a basic study to answer the question: How does the Vietnamese phonetic system exist here? (its current state), what are its similarities and differences compared to Vietnamese in Vietnam, especially compared to the original dialect (in the original homeland) of this community.
1. The Vietnamese initial consonant system of overseas Vietnamese in Mukdahan, Thailand has a total of 22 initial consonants including: /ɓ, th, t, ɗ, ʈ, c, k, Ɂ, m, n, ɲ, ŋ, f, β, s, ʂ, j, χ, ɣ, h, l, r/. Based on the results of comparing the Vietnamese initial consonant system in Mukdahan with the Chinese dialect, it shows that 20 initial consonants have similar characteristics: /ɓ, m, th, t, ɗ, n, ʈ, c, ɲ, k, ŋ, Ɂ, f, s, ʂ, l, j, χ, ɣ, h/. 5 initial consonants have differences: /β, v, z, ʐ, r, j/. Vietnamese in Mukdahan does not have the consonants /v, z, ʐ/, while the Chinese dialect does not have the consonants /β, r/. Based on the results of comparing the initial consonant system of Vietnamese in Mukdahan with the Northern dialect, there are 17 initial consonants with similar characteristics: /ɓ, m, th, t, ɗ, n, c, ɲ, k, ŋ, Ɂ, f, s, l, χ, ɣ, h/. 7 initial consonants have different characteristics: /β, v, z, r, ʈ, ʂ, j/. Vietnamese in Mukdahan does not have the consonants /v, z/, while the Northern dialect does not have the consonants /β, r, ʈ, ʂ, j/.
2. The rhyme system in Vietnamese of overseas Vietnamese in Mukdahan, Thailand consists of three components: medial sound, main sound (vowel) and final sound. When vowels and final sounds combine to form rhymes, they can be divided into 4 types of rhymes: 1) Open rhymes are rhymes that end with vowels, with 12 rhymes. 2) Semi-open rhymes are rhymes that end with final sounds /-w, -j/, with 19 rhymes. 3) Semi-closed rhymes are rhymes that end with final sounds /-m, n, -ŋ/, with 40 rhymes. 4) Closed rhymes are rhymes that end with final sounds /-p, -t, -k/, with 40 rhymes. Compared to the Central dialect, Vietnamese in Mukdahan does not have the archaic rhymes [iŋ, eŋ, ɛŋ, uŋ, o:ŋ, ͻ:ŋ, ik, ek, ɛk, uk, ok, ͻk] and labialized rhymes [uŋm, oŋm, ͻ̆ŋm, ukp, okp, ͻ̆kp]. The other rhymes have more similarities than differences. Compared to the Northern dialect, Vietnamese in Mukdahan does not have labialized rhymes [uŋm, oŋm, ͻ̆ŋm, ukp, okp, ͻ̆kp]. In Mukdahan, the final consonant /-ŋ/ is transformed into the final consonant /-n/ as shown by the following pairs of lingual variants: [iŋnh-in], [eŋnh-en], [ɛ̆ŋnh- ɯn], [ikch-it], [ekch-et], [ɛ̆kch-ɛ̆t].
3. The Vietnamese tone system of overseas Vietnamese in Mukdahan, Thailand has 5 tones: 1) The flat tone has an upward stroke, high pitch, normal voice quality, recorded in [34]. 2) The falling tone has an upward stroke, low pitch, and slack voice quality, recorded in [32]. 3) The falling tone has an upward stroke, high pitch, and stuck voice quality, recorded in [325]. 4) The sharp tone has an upward stroke, high pitch, normal voice quality, recorded in [25]. 5) The heavy tone has an downward stroke, low pitch, and is recorded in [31].
12. Practical application:
The results of the thesis can provide information on changes in Vietnamese phonetics used by overseas Vietnamese in Mukdahan, thereby predicting changing trends, providing additional information for teaching and learning Vietnamese locally, contributing to maintaining and protecting Vietnamese language and culture in the Vietnamese community in Mukdahan in particular, and in Thailand in general.

11. Summary of the new findings of the thesis:
The research study entitled Vietnamese phonetic system of overseas Vietnamese in Mukdahan, Thailand was fundamentally aimed to answer the question regarding how the Vietnamese phonetic system exists there (in the current circumstances). Furthermore, it explores the similarities and differences of Vietnamese in Vietnam and its counterpart, especially when compared with the original dialect (in the native country) of this population.
1. The initial consonant system of Vietnamese of the Viet Kieu in Mukdahan, Thailand has all 22 initial consonants consisting of: /ɓ, th, t, ɗ, ʈ, c, k, Ɂ, m, n, ɲ, ŋ, f, β, s, ʂ, j, χ, ɣ, h, l, r/. The comparison results show 20 initial consonants have similarities, including: /ɓ, m, th, t, ɗ, n, ʈ, c, ɲ, k, ŋ, Ɂ, f, s, ʂ, l, j, χ, ɣ, h/. 5 initial consonants have differences, including: /β, v, z, ʐ, r, j/. Vietnamese in Mukdahan does not have the consonants /v, z, ʐ/ while the Central Vietnamese dialect does not have the consonants /β, r/. Based on the comparison results between the initial consonant system of Vietnamese in Mukdahan and the Northern Vietnamese dialect, there are 17 initial consonants with similarities: /ɓ, m, th, t, ɗ, n, c, ɲ, k, ŋ, Ɂ, f, s, l, χ, ɣ, h/. 7 initial consonants have differences, including: /β, v, z, r, ʈ, ʂ, j/. Vietnamese in Mukdahan does not have the consonants /v, z/ while the Northern Vietnamese dialect does not have the consonants /β, r, ʈ, ʂ, j/.
2. The syllable system in Vietnamese of the Viet Kieu in Mukdahan, Thailand includes three components: schwa sound, main sound (vowel) and ending sound. When vowel and ending sound combined into syllable, it can be divided into four types of syllable: 1) Open syllables are the syllables that end with a vowel, there are 12 open syllables. 2) Half-open syllables are the syllables that end with ending sounds /-w, -j/, there are 19 half-open syllables. 3) Half-closed syllables are the syllables that end with ending sounds /-m, n, -ŋ/, there are 40 half-closed syllables. 4) Closed syllables are the syllables that end with ending sounds /-p, -t, -k/, there are 40 closed syllables. Compared with the Central Vietnamese dialect, Vietnamese in Mukdahan does not have ancient syllables [iŋ, eŋ, ɛŋ, uŋ, o:ŋ, ͻ:ŋ, ik, ek, ɛk, uk, ok, ͻk] and labialization syllables [uŋm, oŋm, ͻ̆ŋm, ukp, okp, ͻ̆kp]. Meanwhile, other syllables have more similarities than differences. Compared with the Northern Vietnamese dialect, Vietnamese in Mukdahan does not have labialization syllables [uŋm, oŋm, ͻ̆ŋm, ukp, okp, ͻ̆kp]. For palatalization syllables in Mukdahan, the ending consonant /-ŋ/ turns into the ending consonant /-n/ as shown through the pairs of palatalization variants, including: [iŋnh-in], [eŋnh-en], [ɛ̆ŋnh- ɯn], [ikch-it], [ekch-et], [ɛ̆kch-ɛ̆t].
3. Vietnamese tone system of the Viet Kieu in Mukdahan, Thailand has 5 tones: 1) “Thanh bar” has a going-up contour, high pitch, normal voice quality, and is recorded [34]. 2) “Thanh Huyen” has a going-down contour, low pitch, slack voice quality, and is recorded [32]. 3) “Thanh Tà” has a going-down-then-up contour, high pitch, creaky voice, and is recorded [325]. 4) “Voice” has a going-up contour, high pitch, normal voice quality, and is recorded [25]. 5) “Heavy bar” has a going-down contour, low pitch, and is recorded [31].
12. Practical applicability, if any:
The results of the thesis can provide information on the changes in Vietnamese phonetics used by overseas Vietnamese in Mukdahan. Hence, the thesis can also predict changing trends, provide more information for teaching and learning Vietnamese locally, and contribute to maintaining and protecting the Vietnamese language and culture in the Vietnamese community in Mukdahan in particular and in Thailand in general.
