This paper summarizes the main results from the Speaker
Verification (SV) research pursued so far in the CAVE
project. Different state-of-the art SV algorithms were implemented in
a common HMM framework and compared on two databases : YOHO (office
environment speech) and SESP (telephone speech). This paper is concerned with
the different 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.
