This work focuses on the speech perceptions of two different non-native speakers. The selected sample of respondents has the task of expressing their impressions and evaluating the characteristics of both participants. Nationality, various aspects of the voice, imitation skills, and overall impression of the audio recordings will be considered. The aim of this study is to verify whether the accent and characteristics typical of a given nationality can be recognized from the speech of the performers. The present thesis will also analyze how accurately an evaluator can identify the linguistic background.
