| Research Abstract |
A framework for Audio-Visual Integration (AVI), which can provide optimal integration according to quality of audio and visual information obtained from a robot’s camera and microphone, was proposed and implemented. In addition, the proposed framework was extended by proposing “Active Audio Visual Integration (AAVI)”, which improves the quality of audio and visual information using active robot ’ s motion. Preliminary experiments on automatic speech recognition and voice activity detection showed that the AAVI framework worked effectively even in visually and/or auditorily noisy conditions.
