SPEAKER VERIFICATION IN THE TELEPHONE NETWORK : RESEARCH ACTIVITIES IN THE CAVE PROJECTFr
نویسنده
چکیده
This paper summarizes the main results from the Speaker Veriication (SV) research pursued so far in the CAVE project. Diierent state-of-the art SV algorithms were implemented in a common HMM framework and compared on two databases : YOHO (of-ce environment speech) and SESP (telephone speech). This paper is concerned with the diierent design issues for LR-HMM-based SV algorithms which emerged from our investigations and which led to our current SV system , which delivers Equal Error Rates below 0.5 % on a very realistic telephone speech database.

Banks, amongst other businesses, will soon be under a great deal of pressure to improve the range and friendliness of their telephone-based services without compromising transaction security. Currently, automatic telephone services authenticate callers using a PIN-code and consequently do not offer a sufficient level of security for significant transactions; more sophisticated services, which d...

متن کاملCAVE - Speaker verification in bank and telecom services
The CAVE project aims at implementing and assessing two demonstration systems that are using speaker verification (SV) technology. In order to provide scientific grounds for the technological choices that are made for building these demonstrators a large number of available SV techniques have been investigated. The SV techniques have been evaluated using the YOHO and SESP databases and the resu...
