A Review on Multimodal Speaker Recognition

Abstract

A review on multimodal speaker recognition (SR) is being presented. For many decades, the SR has been studied, and still, it has grabbed the interest of many researchers. SR includes two levels -system training and system testing. The robustness of the SR system depends on the training environment and testing environment as well as the quality of speech. Air conducted (AC) speech is a source, from which speaker is recognized by extracting the features. The performance of the SR system depends on AC speech. Further to improve the robustness and accuracy of the SR system various other sources (modals) like throat microphone, bone conduction microphone, array of microphones, non-audible murmur, non-auditory information like video are used in complementary with standard AC microphone. This paper is purely a review on SR and various complimentary modals.
