A report recently released shows that the
proficiency of English of Taiwan adults is
ranked 30 and categorized into
“intermediate-low level”, falling behind
neighboring countries such as Japan and
Korea.

11. Literature Review
An important tenet of structural linguistics
was that the primary medium of language
is oral: Speech is language.

12. Literature Review
The advantages of CALL-based
pedagogy over conventional materials are
in the provision of self-paced learning,
patient tutoring, immediate and
individualized instruction, and detailed
records of achievement.

13. Literature Review
Teaching pronunciation with CAPT
Pronunciation of difficult and unknown
words significantly in a time period
(Neri et al., 2008)
Acquisition of second language prosody and
generalization to segmental accuracy and
novel sentences with automatic visual
display of the speaker’s intonation
