2. Background of the Problems
I am an Indian, very brown, born in Malabar,
I speak three languages, write in two, dream in one.
Don’t write in English, they said,
English is not your mother-tongue.
Why not leave me alone, critics, friends, visiting cousins,
Everyone of you? Why not let me speak in any language I like?
The language I speak becomes mine,
its distortions, its queernesses, all mine, mine alone.
It is half English, half Indian, funny perhaps, but it is honest.
It is human as I am human, don’t you see?
It voices my joys, my belongings, my hopes.
And it is useful to me as cawing is to crows or roaring is to lions,
It is human speech, the speech of the mind that is here and not there,
A mind that sees and hears and is aware. not the deaf, blind speech.
(Kamala Das: ‘An Introduction’, 1965)

3. Introduction Standard English Only
Standard English will be appropriate in all contexts of English language use.
(Quirk, 1985: 1)
Standard English as King English.
(Phillipson, 1992)
Native English possesses no less intelligibility than indigenous English accents.
(Trudgill, 2003)

4. Introduction Non Standard English Allowance (Krachu, 1962)
Concentric Circles of English Users
(Krachu, 1962)
English does not belong to any specific group of people but it belongs to whoever the interlocutor is.
(Kirkpatrick, 2007)
The Dynamic of New English
(Schenider, 2007)
Lingua Franca Core Concept
(Jenkins, 2000)

5. Introduction
Kachru's Three Concentric Circles of English

6. Literature Review Lingua Franca Core
A theory arguing that some English speech sounds are more crucial than others in promoting communication
Rather than possessing native-like pronunciation, non-native pronunciation is permissive as long as the intelligibility is reached.

7. Intelligibility Analysis
Literature Review
Intelligibility Analysis
Intelligibility
Recognition of words and utterance
Comprehensibility
Ability to ascertain a meaning (Locutionary Force)
Interpretability
The degree to which one is able to perceive the intention behind another’s word of utterance (Illocutionary Force)
(Smith, 1987)

8. Speech Intelligibility Testing
Literature Review
Speech Intelligibility Testing
Speech Recognition, Speech Understanding
Needs to be qualitatively judged by human only (Holmes and Holmes, 2001: 210)
Transcription Task: American Standard Method for Measurement of Monosyllabic Word Intelligibility

Text Independent
(Holmes and Holmes, 2001: 224)

9. Research Questions
1. How does the degree of Thai accentedness – weak, moderate, and strong, in Thai English pronunciation have the impact on the intelligibility to different groups of English users; namely,
a) English native speakers?
b) English non-native speakers whose L1 is not Thai?
c) English non-native speakers whose L1 is Thai?
2. Which specific pronunciation features of Thai English pronunciation cause the problem in the intelligibility to different groups of English users; namely,

10. Methodology Participants 9 English Language Users
3 English Native Speakers
3 English Non Native Speakers (non Thai L1)
3 English Non Native Speakers (Thai L1)

11. Audio Recorded Speech (10 mins) Controlled topic (Dissertation)
Methodology
Informants
2 Thai English Speakers (weak accent)
2 Thai English Speakers (moderate accent)
2 Thai English Speakers (strong accent)
Audio Recorded Speech (10 mins)
Controlled topic (Dissertation)
Judges for Level of Accentedness
3 linguist experts
10 non-linguist experts

12. Methodology Instruments Data Analysis: Transcription Tasks
Accurate Transcription – Level of intelligibility possessed by each group of listeners
Error Transcription – Phonological features to be focused in teaching English pronunciation for Thai students

13. Data Analysis
Intelligibility Level

14. Data Analysis
Problematic Phonological Features
Segmental Features
Consonants
[dʒ] as [ʃ] – genre
[z] as [s] - design
[v] as [w] - environmental
[θ] as [t] - there

15. Data Analysis
The pronunciation of unreleased final consonant
[r], [t], [k], [z], [d], [n]
[s] always replaced with unaspirated [t]
[l] always replaced with glide [w]
Replace rhotic [r] with lateral [l] – ‘lecturer’

16. Data Analysis
Fail to produce certain group of consonant cluster
[dr] as [dʷ] - dressing
[fr] as [f] (drop [r]) - different
[pl] as [pr] - applied

17. Data Analysis
Vowels
Monopthongization
[əʊ] as [ɔ] - approaches
[ēə] as [e] - lesbianism
Strengthen unstressed weak vowel [ə] as stressed vowel as
[e], [a], [ɔ], [æ]

18. Data Analysis
Suprasegmental Features
Stress: wrong placement of stress especially in the words with more than two syllables ‘literature’ ‘cinematic’

19. My Research Journey Obstacles
It is inappropriate to judge the quality of any language as language is merely the tool for communication.
Level of intelligibility should not be measured only in term of pronunciation. In fact, grammar, style, and fluency performed by individual speakers come to the play.
Certain Thai English informants do not want to be the informant of the research.
