Speaker ID

From LRDE


Speaker recognition

The work of LRDE Speaker ID team is conducted in collaboration with the Spoken Language Systems Group of the MIT Computer Science and Artificial Intelligence Laboratory.

Evaluation campaign of the NIST-SRE speaker verification systems

We participated in the evaluation campaign of speaker verification systems organized by NIST: the National Institute of Standards and Technology organizes competitions in various fields, both to stimulate research and to define new standards

since the beginning of the project. In 2006, we proposed a system based on GMM-UBM and a GMM-SVM system based on the Gaussian kernel without any channel compensation techniques.

In 2008, we proposed a fusion of several systems: we fuse two systems based on SVM methods with linear kernel and non-linear kernel with three systems based on prosodic parameters allowing to represent the long-term characteristics of the speech signal.

In 2010, the proposed system uses the I-Vectors to represent the speaker and the techniques described in the previous section for the compensation of the channel. We participated for the first time in the task 10sec-10sec.

We managed to improve the performance of our system every time.
