INACCURATE PRONUNCIATIONS OF ENGLISH VOWEL SOUNDS BY ONLINE INDONESIAN ENGLISH TEACHERS

Many English learners use English Teaching Channels on YouTube as an alternative source of learning. Most of those channels were organized by Indonesian teachers. However, the qualities of the teaching presentations on these channels are varied. Inappropriate use of vocabulary, inaccurate grammar, and mispronunciations are often found in these channels. This research attempts to study the inaccurate pronunciations of the English teachers. The study is necessary due to the fact that learners consider online English teachers as good language model and as an alternative to access English learning materials. The result of the study shows that there are nine types of English vowels that are pronounced inaccurately by the teachers. Ten of the inaccurately pronounced English vowels are absent in Indonesian vowel system. The finding of the research, therefore, can be cautions and suggestions for viewers of English Teaching channels on YouTube, and Indonesian English teachers when learning English and or teaching this language online.
