In this paper we present the continuation of our research on the ability of native Greek adults to identify their mother tongue from synthesized stimuli which contain only prosodic - melodic and rhythmic - information. In the first section we present the ideas that underlie our theory, together with a brief review of our preliminary results. In the second section the detailed description of our experimental approach is given, as well as the results and their statistical analysis. In the final two sections we provide the conclusions derived from our experiments and the future work we are planning to carry out.
