Chapter One IntroductionChapter One IntroductionBackground and MotivationBackground and Motivation

Due to CLT & GEPT, pronunciation is important to build up communicative competence.

Take Jason for example.English learners have problems with the production and

perception of /æ/ since Mandarin and Southern Min.

Mandarin: / ㄟ /, / ㄝ /-- /e/,/ɛ/ in English

Southern Min: /e/---/e/ & /ɛ/

PurposePurpose of the Studyof the StudyThe study is to examine students’ production and

perception of the three front vowels. Fledge (1993) points out that production follows from

perception.Sheldon &Strange (1982) found that production

exceeded perception.Taiwanese students, whose mother tongue is

Southern Min, will have a hard time differentiating the English vowel /e/ and /æ/ due to transfer of L1 to Mandarin and English.

Research QuestionResearch Questionss 1. Can the subjects identify the three front vowels

/e/, /ɛ/ and /æ/?

2. How is the subjects’ performance of their pronunciation of /e/, /ɛ/ and /æ/?

3. In what range is the subjects’ performance of production intelligible for English native speakers?

4

Significance of the StudySignificance of the Study

The acoustic data and the results of the study can serve as a guide for English teachers in Taiwan to refer to.

5

Limitations of the StudyLimitations of the Study

1. The subjects are in the third grade from the same school.

2. The subjects have the same English teacher.

3. There are uneven number of male and female subjects.

4. Because the vowels /ɛ, æ/ can not appear in a purely open syllable as can /e/, the stimuli in the phonetic environment of open syllables in the listening task had to be designed equally in the first of the two syllables as a comparison.

Chapter Two Literature Review ContrastiveContrastive AnalysisAnalysis (CA)(CA)

Lado (1957)

Comparing a language and culture to be learned with the students’ native language and culture can predict and describe in which areas language learners will have difficulties.

similar to L1 → easy different to L1 → difficult similar to L2, not the same position

→ difficult

7

MarkednessMarkedness

Eckman (1977) The Markedness Differential Hypothesis predicts the

difficulty of a L2 language learner based on the relative degree of markedness of the native language and the target language.

Less marked phenomena are acquired before the more marked.

DataData AnalysisAnalysis

• Perception

The program Excel VBA was adopted to produce and S-P table, in which the researcher could examine which sounds were easier to distinguish and which one were the most difficult.

• Production

(1) The two native speakers and one non-native experienced English teachers were invited to listen to the subjects’ recordings together as evaluators’.

With regard to the subjects’ performance in perception

1. /ɛ/ is the most difficult and /æ/ is the easiest one to perceive.

2. The vowel /e/ in closed syllable with a voiceless consonant is more difficult to perceive.

3. The vowel /ɛ/ in closed syllable with a voiced consonant is more difficult to perceive.

4. The vowel /æ/ in open syllable is more difficult to perceive.

5. Those who did better on the written test of English –GSAT- also performed better on the perception task of English.

1. The vowel /e/ displays the most difficulty in the subjects’ production and the success in pronouncing /æ/.

2. The vowel /e/ in the closed syllable with a voiceless consonant displays more errors.

3. The vowel /ɛ/ in the closed syllable with a voiceless consonant displays more errors.

4. The vowel /æ/ in the closed syllable with a voiceless consonant displays more errors.

General Intelligible Ranges of ProductionGeneral Intelligible Ranges of Production for Natives for Natives

RQ3: In what range is the subjects’ performance of production intelligible for English native speakers?

29

The range of intelligibility in vowel length is wide because the length varies with the speed of production.

30

MLAE seemed to fossilize their tongue position more than the other groups when pronouncing these three vowels, fixed to a more raised tongue height.

31

lowest

The range intelligibility in tongue advance of /æ/ does not seem to matter that much, but the tongue advancement of /e/ must be anterior to that of /ɛ/.

Posterior tongue position

With regard to the intelligible ranges of the With regard to the intelligible ranges of the subjects’ productionsubjects’ production

1. The length of the vowels /ɛ/ and /æ/ can be longer than each other. The length of the vowel /e/ has to be the longest of the three.

2. LAE’s performance of tongue height tended to stay raised, MLAE in particular, fossilizing their tongue position more when pronouncing the three vowels.

3. The tongue advancement of /æ/ does not matter much, while the tongue advancement of /e/ must be anterior to that of /ɛ/. MHAE tended to move tongue more forward when pronouncing the three vowels. The female subjects tended to keep their tongues farther back.

32

General Discussion (1/3)General Discussion (1/3)

The perception experiment It was speculated in the chapter one that English learners

in Taiwan had problems with the production and perception of /æ/. The result turned out opposite.

Reasons:

1. The researcher teaches three vowels in class.

2. It is “new” sound for those whose first language is Mandarin or Southern Min.

Taiwanese people used Southern Min /e/, so they neglect the difference between the long, tense (/ ㄟ /) and the short (/ ㄝ /) vowels in Mandarin. Their production of English non-high front vowels thus lack discrimination.

33

General Discussion (2/3)General Discussion (2/3)

The production experimentThe result is different from /ɛ/ the same phonetic

environment of the perception much.The poor perception of it does not seem to affect its

production much.The result of the four groups has a lot of devotion to

English learning. (e.g. fondness, time, cram school, self-study)

34

General Discussion (3/3)General Discussion (3/3)

The evaluators’ assessmentThe word list is examined by the native English

speakers with a higher standard of evaluation because there was nothing else before and after the single words to rely on perceiving what the subjects were conveying.

35

Chapter Five ConclusionChapter Five ConclusionPedagogical ImplicationsPedagogical Implications

Instructors have the duty to raise students’ awareness of the sounds they hear.

Teachers must highlight that students the position of their tongue.

Smaller scopes of production, the significance of accurate articulation can not be ignored.

Precise and demanding instructions are important to lay the firm groundwork for good command of English.

36

Suggestions for Further StudySuggestions for Further Study

1. While selecting subjects, researchers should take their language instructors into considerations.

2. The design of the list for the listening task is important. It is better to set up the listening experiment in a parallel way to the production experiment.

3. It will be interesting to add /ɑ/ to the three in the study.

37

CommentsComments If the researcher did not teach three front vowels before

doing the research, the result would be more precise. In the task of sentences and passages, native speakers

need to point out the errors that subjects made, but it might be not correct enough.

The rate of correct responses to the stimulus T-/bet/x2 is higher than the other three. Likewise, the stimuli T-/pled/x1 and V-/pled/x1 obtained higher rate of correct response than T-/pled/x2 and V-/pled/x2. Additionally, the rate of correct responses to the stimuli V-/dælɪ/x1, V-/bæt/x1 and T-/plæd/x1are low in the categories. It is

doubted that the major factors to cause the prominent differences. (p.19, 20, 21)
