SPEAKER VERIFICATION IN THE TELEPHONE NETWORK : RESEARCH ACTIVITIES IN THE CAVE PROJECTFr
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 fr...
متن کاملCAVE – Speaker Verification in Banking and Telecommunications
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 کاملThe CAVE Speaker Verification Project - Experiments on the YOHO and SESP Corpora
Many businesses, such as banks, will soon be under pressure to improve the functionality and friendliness of their telephone-based services without compromising security. Current automatic services authenticate callers with a PIN-code and consequently are not secure enough to ooer callers the chance to carry out signiicant transactions; more sophisticated services necessarily depend on a human ...
متن کاملA comparison of a priori threshold setting procedures for speaker verification in the CAVE project
The issue of a priori threshold setting in speaker veri-cation is a key problem for eld applications. In the context of the CAVE project, we compared several methods for estimating speaker-independent and speaker-dependent decision thresholds. Relevant parameters are estimated from development data only, i.e. without resorting to additional client data. The various approaches are tested on the ...
