Introduction
The relationship of the primary stress and intelligibility motivates The teaching of suprasegmentals
What is the Suprasegmental?
•Stress•Intonation•Timing•Rhythm •juncture
The Purpose of This Study
Whether the correct placed primary stress affects the processing, comprehension, and evaluations of the native speak listeners
Background knowledge
1.Teaching the NNS supra- segmentals does improve the intelligibility of their speech.2. Isolated primary stress※NNS means the nonnative speakers
How to realize the primary stress
By combining a detectable change in pitch with increased vowel duration and intensity
Example:
A: Are you ready?B: I’m always ready.
The GNSC
(Given-new stress connection): new and contrastive information is presented in stressed elements, and old or given information is expressed in unstressed elements.
The Chinese learners’use
the primary stress
Chinese learners used pitch movement of every word in a message unit.
Example:
Correct Wrong 1 2 1 1Living room→ Living roomBook store → Book store
Two Problems
1.Misplacing primary stress
2.Stressing all words
Method
An experimental study was designed using oral texts constructed to systematically vary the GNSC.
Subjects
90 subjects, 30 each to 3 experimental groups
They are first-semester freshman students, come from Midwestern public university and speak North American English
Materials
Three versions of a text recording by a Korean. Digital editing techniques make sure these three versions equal, including volume and length (4.5 minutes).
Three versions
Version A: GNSC was maintained. Version B: GNSC was violated through misplaced primary stress. Version C: GNSC was violated through absence of primary stress.
The main purpose1. Measure of Difficulty Processing Discourse * Dual-task paradigm * The participants’ primary task was A. to understand and remember the lecture’s content B. to monitor for a tone presented in the background of the speech
2. Measure of Comprehension
* The study measured in two ways(1)subjects were asked to write down as
much as they could recall from the lecture (2)a short-answer comprehension quiz * The questions elicited each main idea in
the lecture.
3. Measure of Evaluative Reactions to the
Speaker
* Instructor and Course Evaluation System (ICES) Item
Catalog: use to collect feedback from students on their classroom instruction.
Procedure 30 30 30
First, the researcher explained the instructions and
the format of the experiment.
Second, specific instructions and practice for
the reaction time task were provided on the
computer.
Third, the subjects were then informed
that they would be listening to a TA and
were then asked to complete the reaction
time task, the recall, the quiz, and the
ICES ratings in that order.
RESULTS
As shown in the following Table:

Discussion
This consistent pattern in the results supports the general proposition that correct primary stress in extended nonnative discourse facilitates communication.
Implications for ITA programs and curricula
It therefore seems logical that the ITA curriculum
should include instruction in primary stress.
A broad perspective that acknowledges the various roles that pronunciation features play in communicating meaning in discourse would enhance ITA programs and materials.
Implications for pronunciation pedagogy and
materials
Fortunately, primary stress can be learned, primary stress is both
teachable and valuable for communicating.
Conclusion
This research provides evidence that primary stress contributes significantly to the intelligibility of nonnative discourse, and it strengthens the broadly stated claims in the pedagogical literature on ESL pronunciation that teaching suprasegmentals is important.
