An overview of the PICASSO project research activities in speaker verification for telephone applications
- 1999
-
Conference paper (peer-reviewed)abstract
- This paper presents a general overview of the current research activities in the European PICASSO project on speaker verification for telephone applications. First, the general formalism used by the project is described. Then the scientific issues under focus are discussed in detail. Finally, the paper briefly describes the Picassoft research platform. Along the article, entry points to more specific work also published in the Eurospeech’99 proceedings are given.

An overwiev of the CAVE project research activities in speaker verification
- 2000
-
In: Speech Communication. - 0167-6393 .- 1872-7182. ; 31:2-3, s. 155-180
-
Journal article (peer-reviewed)abstract
- This article presents an overview of the research activities carried out in the European CAVE project, which focused on text-dependent speaker verification on the telephone network using whole word Hidden Markov Models. It documents in detail various aspects of the technology and the methodology used within the project. In particular, it addresses the issue of model estimation in the context of limited enrollment data and the problem of a posteriori decision threshold setting. Experiments are carried out on the realistic telephone speech database SESP. State-of-the-art performance levels are obtained, which validates the technical approaches developed and assessed during the project as well as the working infrastructure which facilitated cooperation between the partners.

A comparison of a priori threshold setting procedures for speaker verification in the CAVE project
- 1998
-
Conference paper (peer-reviewed)abstract
- The issue of a priori threshold setting in speaker verification is a key problem for field 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 Dutch SESP database.

The CAVE-WP4 generic speaker verification system
- 1998
-
In: RLA2C 1998 - Speaker Recognition and its Commercial and Forensic Applications. - : International Speech Communication Association. ; , s. 202-205
-
Conference paper (peer-reviewed)abstract
- This papers describes the generic speaker verification system that was developed within Work Package 4, which was responsible for Research and Technology improvements for Speaker Verification in the CAVE project. With this perspective, different SV algorithms were implemented in a common HMM framework and compared on several databases. This paper is concerned with the design of this generic system and not with the experiments we performed using the system. It shows the importance of having a common and generic package for cooperative research. We intend to make the Generic System available to the research community.
