Chapter One Introduction
•
Statement of the Problem
1. Teaching of pronunciation be integrated :
drillings of individual sounds  use of discourse intonation
in contexts.
2. Previous studies shown the contradictory results :
a)No apparent relationship to pronunciation ability (Suter, 1976)
b) Not really have beneficial effects of gaining the mimicry
ability of L2 utterances (Neufeld, 1988)
3. Very little evidence exists :
Specific topic of sentence prominence might be beneficial for
nonnative speakers from distant tone-language background
Research Question
1.
What prosody features characterize the Chinese EFL
learners’ sentence prominence in English connected
speech?
2.
Would the Chinese EFL learners, with informed
practice, be able to improve their production of
English sentence prominence?
3.
What difficulties might the Chinese EFL learners
have in approximation of target-like sentence
prominence in English connected speech?
Purpose of the Study
-this study can provide an empirically-derived basis
for a refinement of pedagogical and methodological
approach to pronunciation and prosody instruction
and research.

Definition of terms
1.
Stress and Prominence (from A Dictionary of Linguistics
& Phonetics)
Stress : the degree of force used in producing a syllable
Prominence: the degree to which a sound or syllable stands
out from others in its ENVIRONMENT (Crystal, 2003)
2.
Sentence Stress =tonic stress or unmarked cases
(Katamba,1997)
Tonic stress goes on the syllable which carries primary
word stress in the last lexical item of the tone unit. (eg.
noun, adjective ,verb…)
Stress placement  new information  speaker wishes to
highlight
3.
Contrastive/Emphatic Stress =marked cases
(Katamba,1997)
In marked cases, the speaker places prominence
to fall on grammatical (function) words, (eg.
pronoun, preposition, conjunction)
contrastive stress  non-final lexical items  the
speaker wishes to draw attention on such word
Example 1 Q: Is Joan studying FRENCH or GERMAN?
•
A: Joan is studying French ˊAND German.
Example 2 Q: Did you speak to Mr. ´BROWN?
•
A: No, I spoke to ´MRS. Brown
4.
Thought Group/Intonation Unit (Celce-Murcia,
1996)
To segment the speech into smaller units to locate the
prominence. This small unit is called thought
group/intonation unit.
It not only forms a semantically and grammatically
coherent segment of discourse, but also has its own
intonation contour or pitch pattern
Unit boundary 
a.) punctuation mark (eg. comma, period, dash…ect)
b.) a pause ( speakers produce fewer break )
 get the audience’s better attention
Chapter Two Literature Review
•
Prosodic feature = intonation + rhythm
a) Intonation= ‘melodic movement’
 the rise and fall in pitch
b) rhythm = ‘beat’ of the language
 gives it an organization in time
Prosodic System in English
1. English = intonation language + stress-timed rhythm
2. Syntactically (Ladefoged ,2001)
a.) Completion of a grammatical unit or noninterrogative sentences
 FALLING pitch
b.) Incomplete utterances or interrogative sentences
 RISING pitch
3. Semantically
The tonic syllable of an intonation phrase or contour has
significant influence on the meaning of the utterance. (to
emphasis information)
4. Four different factors are important: loudness, length, pitch,
vowel quality. (Roach ,2004),
Prosodic System in Chinese
1. Chinese = tone language + syllable-timed rhythm
2. Structure = CV sequence (Ladefoged, 2001) + Four tones
(Chao, 1948).
Factors Influencing Prosody Acquisition
1. Transfer (+,-) (Odlin, 1989)
-the influence resulting from the similarities and
differences between the target language and any other
language that has been previous acquired
2. Age of acquisition (Han, 2005)
-Whether adults can ever acquire native-like
competence in a second language or for children who
start learning at a relatively early age. (p.219)
-Proficiency of the earlier L2 learner > the later L2 learner
(e.g. Dekeyse, 2000; Johnson and Newport, 1989; Patkowski, 1980).
Factors Influencing Classroom
Pronunciation Learning
• Celce-Murcia, Brinton, & Goodwin (1996)
– (1) the learner: age, exposure to the target
language, the amount and type of prior
pronunciation instruction, and aptitude, attitude
and motivation
– (2) the role of the native language.
Pronunciation and Prosody Teaching
Research
• Few focused specifically on suprasegmental, such as
Hahn’s study (2002) of the primary phrase stress,
suggesting the need of classroom research in this
area.
• Major research designs were experimental,
quantitative approach. Very few qualitative studies
were reported, such as Chang’s (2006) case study.

Two friends went for a walk. On the road they saw a purse. There were a cell phone, some credit
cards, and a lot of money in it. One of the girls picked it up. ‘Look! I got a purse full of money,’ she
said and put it in her pocket. Don’t say “I”, say “We”,’ said her friend. ‘It is our purse, not yours.’ ‘No,’
said her friend. ‘I saw it first, so it is my purse and I am going to keep it.’ Shortly afterwards the
people who had lost the purse came up with them, and the girl who found it, said ‘Oh, dear!’ ‘What
shall we do?’ ‘Don’t say “we”, say “I”,’ said her friend. ‘You picked up the purse, didn’t you?’

3.3 Training Design and Procedures
• Three phases: pre-test, training, and post-test.
• 8-week training for students
(1) to comprehend and produce the sentence stress and
contrastive/emphatic stress in English
(2) to perform the prosody of prominence associated with
the sentence stress and contrastive/emphatic stress
(3) to empower the ability to monitor one’s own speech
when focusing on phonological form.

In the first part of the semester (week 1 to week 8), the students learned
word stress, pausing in longer sentences and short stories, and pitch
change in simple rising and falling intonation patterns

‘Pro-nun-ci-a-tion- i-sim-por-tant’
(Chen, C., Fan, C., & Lin, H., 1997, p.190)
•
To explain the different rhythmic features of English (stress-timed) with Chinese,
which is generally referred to as syllable-timed language
•
Chinese version was represented by a line of soldiers following one another at rather
regular intervals.
•
English version was represented by a series of family members, The underlined
boldfaced syllables –a- and -por- were adults in the sentence, representing the two
primary stressed syllables

General Stress Rule
Predicting stressed and unstressed
words
Prosody strategy:
Perform word stress in content
words and schwa in high-frequency
function words
General Stress Rule
• Content words
– Stressed (emphasized) by adding extra length to
their stressed syllables
– Function words are left unstressed (de-emphasized)
by always reducing the vowel of the unstressed
words.
• Schwa sound [ə] in high-frequency function words
– ‘a’, ‘an’, ‘and’, ‘of’, ‘or’, ‘the’, ‘to’, and ‘for’
– Students worked on critical listening skills, practiced
and produced stressed words and weak forms in
controlled mode.

Critical listening to English rhythm
Prosody strategy:
Perform phrase-final vowellengthening; common expressions;
schwa in high-frequency function words
Sentence Stress Rule
• Stress the last content word in each thought group. The
stressed word should sound longer and have higher pitch than the
other words in the utterance.
• For example, the paragraph looked like this
(the hyphens were the pause marks):
Let me tell you about - my experience as a house father - when
my children were very small - I stayed at home - while their
mother - went to the university - during this time -I learned a lot
of new skill.
• A pause was marked between the subject and predicate, and to
segment the speech into smaller unites which was called
‘intonation unit / thought group’.
Topic 3: Sentence Stress and Weak Forms-1
• Students tap the desk in 4 beats for each stressed word as they
say the first sentence.
• In order to get a good rhythm, students had to learn to squeeze
some words, in this case, ‘and, ‘then’ and ‘it’s’.
Topic 3: Sentence Stress and Weak Forms-2
Students were asked to
add some familiar expressions
to the list and to record.

Survey Questionnaires
3.4 Data Collection and Analysis
• T1 data: Eight male Chinese speakers did the oral
reading task in English before instruction
T2 data: the same story reading right after the
instruction.
• Two male English-speaking models recorded for
target-likeness comparison.
• The qualitative data including questionnaires, weekly
learning logs, and observation analysis of their
prominence perception and production in practice and
production phases.
Chapter Four Results
1. Sentence Stress Analysis (H*)
-Measure the placement: in non-contrastive context and the duration
measurements of the vowels in the last content words in utterance-final
and non-utterance-final position
-The result : a positive improvement of a 26% increase for H* pattern in
sentence stress from Time 1(pre-test) (9%) to Time 2(post-test) (37%)
Comparison between T1 and T2 in vowel duration ratios &
target-likeness in sentence stress
-The result : One(13%) --> Six (75%) subjects’ production was evaluated
as target-like(T2)
-Topic reset = Readers start a new paragraph by using an especially high pitch
at the beginning of the first sentence.
S1 ‘Two friends went for a walk’
S7 ‘What shall we DO?’.
2. Contrastive/Emphatic Stress Analysis (L+H*)
-Measure the placement: contrastive/emphatic stress and the duration
measurements of vowels in contrastive/emphatic words
-The result : a significant improvement of a 40% accurate increase for
L+H* pattern in contrastive/emphatic stress from Time 1 (0%) to Time 2
Comparison between T1 and T2 in vowel duration ratios &
target-likeness in contrasive/emphatic stress
-The result : One (13%) --> five (63%) subjects’ production was evaluated
as target-like, Liu, Zhang, Jian, Chen, and Li
S5 ‘Don’t say “I”, /say “WE”.
S7 ‘What shall we DO?’
3. Questionnaire Analysis (Three categories)
a. The first category : subjects’ starting age of
English learning.
-Young Starters had better prosodic
awareness than that of the Later Starters
b. The second category :subjects’ awareness of L1 and
L2 pronunciation difference
-Young Starters took advantage of native English
teachers in speaking more English and obtaining
pronunciation help
-Later Starters seldom had to speak English and
therefore they did not receive teachers’ help with
pronunciation (focus on vocabulary and reading)
C. The third category : subjects’ reactions to the prominence
instruction
- According to the survey, young Starters were more confident with
placing stress on focus words than the Later Starters
- Young Starters benefited from the familiarity of reading aloud task and
past speaking experience
- A positive responses to the training of prominence strategy use to
stress focus words (see below)
★ Higher pitch(46%) > Longer vowel(29%) > Intuition (14%)
Chapter Five Discussion & Implication
* Response RQ1Chinese EFL learners displayed very small pitch differences
between the stressed prominent words and the neighboring
less stressed or unstressed words in the thought groups + very
few productions of extended vowel duration of the
prominent words either in sentence stress context or in
contrastive/emphatic context
* Response RQ2- A substantial improvement in
prominence production from Time 1 to Time 2
* Response RQ3- no significant difference in learning
prominence in the two contexts introduced, but more
difficulties in approximation of pitch height than in vowel
duration
Limitations
1.
The quasi-experimental study was limited in that it
was a report of selected learners receiving specific
prominence instruction in part of a regular college
pronunciation class
2.
Subjects were a small number of 8 male students
from the same L1 background and the control group was
limited to two English-speaking models
3.
The variable of the prosodic feature of intensity
was not examined, and a few variables were controlled,
such as gender, speech rate, and intonation
