test to the student that consists of 42 words containing related five English
consonantal sounds in initial, medial, and final position. This study found
phonological errors in all of the pronunciation of five English consonantal sounds
in all three positions of occurrences. Students made sixteen kinds of deviations in
all included the replacement of [v] with [f], the replacements of [?] with [s], and
[t?], the substitution of [?] with [?], [z], [s], [t?], [d?], and [g], the replacement of
[d?] with [g], [d?], [t?], and the replacement of [t?] with [t?], [k], [?] and [d?].

fricative, [?], creates many difficulties for students. On the other hand, English
sound [?], voiceless palatal fricative, creates little difficulties for students.
