Production and Perception of Geminate Consonants in English Words by Thai Learners of English: Implications for English Teaching and Learning

The present study aims to explore the production and perception of geminate consonants of Thai learners of English. This study seeks to answer three research questions. First, are there any significant differences in the production of different types of English geminate consonants among five groups of participants (four groups of non-native speakers of English and one group of native speakers of English)? Second, does the level of English proficiency of the English learners affect the production and perception of English geminate consonants? Third, do English orthographic forms affect the pronunciation of Thai learners of English? To answer these three questions, the researcher compared the performance of 90 students from three different levels of language proficiency (low intermediate, high intermediate, and advanced) and of 15 Thai university instructors with the performance of eight native speakers of English. The researcher examined the performance of the participants by using two tasks: reading aloud and dictation. Even though the statistical results showed a significant difference only in the production of lexical geminates between native and non-native English speakers, it should be noted that the students from the lower levels of language proficiency seemed to have greater difficulty in identifying English geminates in regular speech. Ultimately, the researcher would like to argue that teaching pronunciation is not just about teaching students how to produce the correct sounds. It is also about helping them to hear the sounds correctly, so that they can understand what they hear.
