1. Introduction

a. English as a second or a foreign language in Taiwan?

b. English, as a matter of fact, as a third or a fourth language in Taiwan

(i) L1 = native language = Southern Min

(ii) L2 = lingua franca = Mandarin Chinese

(iii) L3 = foreign language = English

What effects to be considered?

1. Contrastive Analysis Hypothesis (Lado 1957)

If x exists in L2 but not L1, it would be difficult to be learned or acquired.

As predicted by CAH:

1. Phonology

Mandarin English

X []: think

[]: within

[]: usual

Question:

If English in Taiwan is a third language, then English would be interfered with the first language (Southern Min) or the second language (Mandarin Chinese)?

L1 L3 L2

The question can be answered on the basis of Taiwanese English learners’ acquisition of English consonants or vowels.

However, the present study is entirely based on vowel acquisition.

Vowel quality: formants

What is a formant?

• Ladefoged: A group of overtones corresponding to a resonating frequency of the air in the vocal tract. [P.293]

• Laver: They (formants) represent the acoustic consequences of the changing shapes of the mouth and pharynx in terms of the varying frequency-values of the resonances of the vocal tract. [P.103)

• Pickett: In speech, the resonances of the vocal tract are called formants.[P.23]

Vocal tract and its type in vowels:

Pickett 1999:41

Vocal tract shapes for vowels:

Page 20: The Acquisition of English Vowels Reflected in Taiwanese EFL Learners Raung-fu Chung Southern Taiwan University rfchung@mail.stut.edu.tw April 27, Hechun

Acoustic cues for vowels:

F1: The value of F1 is in reverse proportion to the height of vowels: If F1 is lower, then the tongue position for the vowel is higher.

F2: The value of F2 is in proportion of the frontness of vowels: If F2 is lower, then it is more fronted in tongue position.
