Graph № 5. Average score of each problem case in Control group. 
Graph 4 shows the results of the pre-testing of each participant in 
the control group. A scale based on 0 to 20 points has been used. The 
scores range from the lowest point 7 (Student 6) to the highest point 17 
(Student 2) in this group. The pre-testing average score in the control 
group is 12.47 points. It comprises the seven cases of phonological 
interference altogether. 
Graph 5 demonstrates the average score obtained in the control 
group in regard to each case of phonological interference individually. A 
scale based on 0 to 10 points (as per the oral test) has been used. It can be 
observed that the highest score of 8.12 points belongs to Case 9. In 
general the participants´ pronunciation of the consonant sounds in Case 9 
is better than in the rest of the cases. According to the outcomes, the most 
problematic case in the control group is Case 8 with 4.47 points out of 
10.
