Usage of a speech constraint for highlighting compensatory strategies developed in production of a second language

This paper deals with the underlining and the prominent display of the compensatory strategies developed by six speakers which are from different geographic regions when they express themselves in a second language very different from their mother native language. The paradigm that had been used in this study is the elocution speed as a speaking constraint in order to investigate the effects of the flow rate on the acoustical parameters of the speech signal. The analysis is performed in both time and frequency domains. We have obtained very interesting results as we have found out that the used constraint allows a good discrimination between different speakers on the basis of their native language.
