Title: Game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To enjoy display even before and after switching of pattern variation and to discriminate a varying direction nearly at a moment. SOLUTION: A game machine such as a pachinko machine, an arranging ball machine is provided with an informing means 8a which makes first pattern variation 8c and second pattern variation 8e which is different from the variation 8c and which is performed switched with the variation 8c cross with each other in a display part 8 and informs which pattern display between the variation 8c and the variation 8e to give pattern variation to in the case of reaching a prescribed timing. When making the variation 8c and the variation 8e cross with each other and switching the pattern variation, one of them is varied and the other is stopped.

Title: Voice recognition device
Inventor: OZAKI YOSHITAKA
IPC: G10L15/00
Filed: 2001-04-05
Abstract: PROBLEM TO BE SOLVED: To reduce the time required for recognition by reducing the time required to read voice data from a disk. SOLUTION: When discrimination is made to determine that a PTT switch has been operated (a step 101), a beep sound is generated (a step 102) and a command to start rotating the disk is outputted to a disk driver (a step 103). Then, audio signals of voice uttered by a user are taken in from a microphone to conduct voice recognition process (a step 104). When a recognition result is obtained, the driver is controlled, talk-back data, corresponding to the recognition result are obtained from the disk and talk-back voice is outputted from a loudspeaker (a step 105). Since the rotation of the disk is started prior to the voice recognition process, the time required to read the talk-back data is reduced, even though the disk is stopped.
