Speaker specific i-vector channel compensation in speaker recognition
- Jean-Luc Bounthong
The i-vector is actually the state of the art in speaker verification. Efficient result was achieved using classifier such as Cosine Distance (CD). Howeverclassification is performed on a global channel compensated i-vector. In this study, we explore the possibility to enroll a speaker and define a speaker specific channel compensation using i-vector. The objective is to improve the classifier performance using our previous work on Self-Organizing~Map to select suitable i-vector. We will compare the performance of our solution with the global channel compensated method.
