Most face and speaker identification techniques are tested on data collected in controlled environments using high quality cameras and microphones. However, the use of these technologies in variable environments and with the help of the inexpensive sound and image capture hardware present in mobile devices presents an additional challenge. In this study, we investigate the application of existing face and speaker identification techniques to a person identification task on a handheld device.

When these techniques are applied on mobile devices where the visual and audio conditions are highly variable, degradations in performance can be expected. Under these circumstances, the combination of multiple biometric modalities can improve the robustness and accuracy of the person identification task. In this paper, we present our approach for combining face and speaker identification technologies and experimentally demonstrate a fused multibiometric system which achieves a 50% reduction in equal error rate over the better of the two independent systems.
