Through the study which was done by Aboulalaei (2014), the results of the pretest and post-test which served as the statistical basis for the groups and a T-test comparison of group means showed a t value of -9.648.The table of T-critical with 58 degree of freedom for .05-level shows T-critical of 1.96. The T-critical is smaller than the t observed -9.648 > 6.781. Our t value is high enough that we can safely reject the null hypothesis.

So the researchers found that the Computer Assisted Language Learning (CALL) had a significant effect on speaking skill of Iranian EFL Learners.

But the important part of the story is that: Is there any relationship between Computer Assisted Language Learning (CALL) and speaking skill of Iranian EFL Learners? Of course the researchers found a reasonable answer to the research question; that is, there is a reasonable relationship between CALL and Iranian EFL learners' speaking skill.

According to the researchers' experience as computational linguists teaching and doing research in different language institutions presented important and profited opportunity to learn and teach an especial language through the computer and internet.
