ABSTRACT:
A viewpoint of a user is detected in a viewpoint detecting process, and how long the detected viewpoint has stayed in an area is determined. The obtained viewpoint and its trace is displayed on a display unit. In a recognition information controlling process, the relationship between the viewpoint (in an area) and/or its movement, and recognition information (words, sentences, grammar, etc.) is obtained as weight P(). When the user pronounces a word (or sentence), the speech is inputted and A/D converted via a speech input unit. Next, in a speech recognition process, a speech recognition probability PS() is obtained. Finally, speech recognition is performed on the basis of a product of the weight P() and the speech recognition probability PS(). Accordingly, classes of the recognition information are controlled in accordance with the movement of the user's viewpoint, thereby improving the speech recognition probability and the speed of recognition.
