Integration of Speaker Recognition into Conversational Spoken Dialogue Systems.

摘要

In this paper we examine the integration of speaker identification/verification technology into two dialogue systems developed at MIT: the Mercury air travel reservation system and the Orion task delegation system. These systems both utilize information collected from registered users that is useful in personalizing the system to specific users and that must be securely protected from imposters. Two speaker recognition systems, the MIT Lincoln Laboratory textindependent GMM based system and the MIT Laboratory for Computer Science text-constrained speaker-adaptive ASRbased system, are evaluated and compared within the context of these conversational systems.
