Speaker verification

Advanced telephone applications will inevitably grow from pure information systems to mixed information and transaction systems. Security and fraud prevention then become major issues. Card Services of Dutch PTT is investigating the possibility of using speaker verification as one means of fraud combatement. In its original specification the POLYPHONE corpus is not suited for research into speaker recognition. Nijmegen University, in collaboration with the Dutch National Forensic Science Laboratory, have made additional recordings of 100 speakers who have called eight times, using different handsets. Half of the speakers is recruited from the Nijmegen area, the other half from the Hague, in order to minimise dialect differences. Also, the speakers form 50 pairs of brothers or father-son, in order to allow us to investigate whether speaker recognition techniques can be fooled by close relatives.
