This paper reports on a comparative study of several automatic speaker verification systems using the Polycost database. Polycost is a multi-lingual database with non-native English and mother-tongue speech by subjects from 14 countries. We present results for the first three baseline experiments defined for the database as well as explore the multi-lingual aspects of Polycost in a number of experiments where we compare cross-language and same-language impostor attempts. Our results then lead us to suggest a revised set of baseline experiments.
