errors related to vowel iː, error related to vowel ʊ, and etc. by applying the
theory proposed by Roach 1984: 10-35. Then the errors were classified into the types of consonant such as errors related to consonant
ʃ, errors related to consonant
θ, and etc. by applying the theory proposed by Roach 1984: 10-35. Fourth, the data was crosschecked by observing the other sources or information;
in this point, Oxford Dictionaries was used as a supporting source to show the correct pronunciation of a word.
The second stage also consists of several steps. First, the data was checked by listening to the recordings of the interview one by one carefully; the data was
noted down while listening to the recordings. Earphone or headphone was used as an aid during the listening process. Second, the data was rechecked by listening to
the recordings and comparing it with the notes that had been written. Third, the data obtained was classified according to the factors contributing to the errors;
such as the errors contributed by Interlingual Errors, Over-generalization of Rules, Ignorance of Rule Restrictions, Incomplete application of rules, and False
concepts hypothesized by applying the theory proposed by Richard 1974: 174. Fourth, the data was crosschecked by observing the other sources or information.
Oxford Dictionaries was used as a supporting source to give the supporting ideas.
