Perception and production of English vowels by native Iraqi Arabic learners.
Doctoral thesis, Universiti Putra Malaysia.
Abstract
A crucial step in learning to communicate in a second language is to acquire its
phonetic system. Accurate perception and production of the L2 phonemes set the
groundwork for effective communication. However, speaking with accented-free
pronunciation is difficult for EFL learners as everyone has a particular accent. No
formal investigation, to the best knowledge of the researcher, investigated problems
faced by Iraqi EFL learners. Moreover, L1 (Iraqi Arabic) influence on facilitating or
complicating the acquisition of certain L2 (English) segments and how far L2
experience affects perception and production skills have not been investigated with
this group of learners. There is also an ongoing debate on the relationship between
perceptual abilities and production accuracy, and this study will fill these gaps in the
literature. This study aims to investigate the perception and production of English
vowels by Iraqi EFL learners to identify L1 influence and proficiency effects on
these processes. The study also investigates the perception-production relationship.
To achieve these aims, a word identification task and a reading task were conducted.
Eighty-five Iraqi EFL learners participated in this study. They were divided into four
groups based on their proficiency level. The results obtained from the word
identification task and the results obtained from rating for the production task were
analysed using various statistical tests. The results revealed that Iraqi EFL learners
faced considerable difficulties in the perception and production of most vowels.
Patterns of errors made by learners also indicated considerable similarities among
the four groups, which suggests a systematic underlying influence on their
perceptual and production behaviour. L1 influence was found to be a major factor in
accounting for the results of this study. The L2 vowel space was also helpful in
resolving inconsistent results. The learners’ performance revealed significant
proficiency effects offering support to the experience effects hypothesized in the
Speech Learning Model. However, proficiency effects were not identified among all
groups or among all vowels suggesting that the acquisition of certain L2 phones did
not improve due to perceptual reasons and/or L1 influence. The results showed that
speech perception and production are significantly different from one another,
indicating an asymmetrical relationship between them where speech production can be better developed than speech perception, particularly for the elementary group.
The study concluded that the assumption that inaccurate perception should result in
inaccurate production is not well supported in this study, especially among
beginners. Current L2 speech learning models are generally successful in predicting
and interpreting most of the difficulties encountered by Iraqi EFL learners; yet none
of them can independently account for the all the data.
