Abstract
In this paper, we evaluate a speaker verification system in the framework of a common project between IDIAP and ASCOM. The system used is based on new text-dependent speaker verification technologies. The validation has been done on a telephone speech database that contains more than one hundred speakers and the results obtained are between 2% and 4% half total error rate (HTER), which is acceptable for many applications.
