Summary
Based on the observation of the students of Matthayom Suksa 4 at
Assumption Convent Lamnarai School, when pronouncing English vocabulary,
and the research reviewed earlier, the students obviously had a problem of
pronouncing of a final /-l/ sound. Hence, their pronunciation should be
improved. This study attempted to develop a CAI program for improving the
students pronunciation ability and compare the improvement of their
pronunciation after using the CAI program. Lastly, the students’ reactions to
the use of CAI were gathered through the interviews.
