4.2.2. Results

In order to calculate the evolution of the learner’s pronunciation skills within each group
from the first recordings to the second recordings, the following mathematical formula was
used:

[(target value – source value) / source value ] x 100 

The source value corresponds to the the pre-training score, and the target value is the posttraining
score. The result gives the pre-training to post-training evolution, expressed in
percentage.
