✦ Synopsis
In this paper, we demonstrate that use of a recently proposed feature set, termed Maximum Auto-Correlation Values, which utilizes information from the source part of the speech signal, signiÿcantly improves the robustness of a text independent identity veriÿcation system. We also propose an adaptive fusion technique for integration of audio and visual information in a multi-modal veriÿcation system. The proposed technique explicitly measures the quality of the speech signal, adjusting the amount of contribution of the speech modality to the ÿnal veriÿcation decision. Results on the VidTIMIT database indicate that the proposed approach outperforms existing adaptive and non-adaptive fusion techniques. For a wide range of audio SNRs, the performance of the multi-modal system utilizing the proposed technique is always found to be better than the performance of the face modality.
