There are two main areas of pronun
ciation teaching and learning: segmentals
and suprasegmentals. Segmental refers to
the individual sounds and suprasegmental
refers to rhythm, stress, prominence and
intonation. Many material writers, teachers
and researchers have stated that the
suprasegmental aspect should be the first
aspect for language learners to learn [3
This is because learning about supraseg
mentals can help language learners increase
their self-confidence in speaking
Acquiring an understanding of
suprasegmentals is a problem for Thai
learners because of the difference between
the Thai and English sound systems [5, 6, 7].
Moreover, they have difficulty pronouncing
the primary stresses in English words [8, 9].
To reduce the errors in communication for
Thai learners who learn English as a foreign
language, learning word stress and intonation
is absolutely essential.
Advancements in information
technology have helped people to connect
more easily with each other. Moreover,
anybody with access to the Internet can
search for information from anywhere in the
world. So, technology and computers are very
important in everyday life.
In Thailand, there are only a few
suitable programs for teaching English word
stress, sentence stress and intonation at
the Thai university level. This research will
focus on the lessons regarding English word
stress, sentence stress and intonation for
second year English students at Khon Kaen
University studying one of these so-called
suitable programs. The potential benefits of
this type of courseware has led to its inclusion
in this research as it covers the development
of computer-assisted musical pronunciation
courseware for teaching English supraseg
mentals to Business English learners at
Khon Kaen University
