The purpose of this paper is to investigate whether native Greek adults can identify their mother tongue from synthesized stimuli which contain only prosodic - melodic and rhythmic - information. More specifically we are trying to investigate whether Greek native speakers are able to discriminate their mother dialect form another one, also from Greece, only from prosodic information. In the first section we present the main ideas underlie our work, in the second section we present the procedure we followed in order to complete this pilot study, while at the two final sections one can find the results and the conclusions of our experiments.
