Abstract

Automatic speech recognition (ASR) holds the promise of providing a natural, efficient, and safer means for communication between humans and computers and can profoundly change the way we live. Since its invention in the 1950s, ASR has witnessed considerable research activities and in recent years is finding its way into practical applications as evidenced by more and more consumer devices such as PDAs and mobile phones adding ASR features. While mainstream ASR has focused almost exclusively on the acoustic signal, the performance of these systems degrades considerably in the real-world in the presence of noise. One way to overcome this limitation is to supplement the acoustic speech with a visual signal that remains unaffected in an audibly noisy environment, yielding what is known as audio-visual automatic speech recognition (AVASR).
