    • A spectrum calculating unit calculates, for each of the frames, a spectrum by performing a frequency analysis on an acoustic signal. An estimating unit estimates a noise spectrum. An energy calculating unit calculates an energy characteristic amount. An entropy calculating unit calculates a normalized spectral entropy value. A generating unit generates a characteristic vector based on the energy characteristic amounts and the normalized spectral entropy values that have been calculated for a plurality of frames. A likelihood calculating unit calculates a speech likelihood value of a target frame that corresponds to the characteristic vector. In a case where the speech likelihood value is larger than a threshold value, a judging unit judges that the target frame is a speech frame.

    • A 5-direction key operating device is provided in which the structure of diaphragm contacts disposed on a printed circuit board is improved to allow five diaphragms to be disposed in a minimum space, and a single button key is enabled to operate the five diaphragms. Moreover, a 5-direction key operating device is provided in which an operation space can be reduced, and desired one of information displayed on a display section can be selected and determined by a smooth key operation without causing an erroneous operation.In each of diaphragm contacts on which diaphragms (4) that are arranged in the shape of a cross in correspondence with 5-direction keys are to be placed, a circular contact (1) which is a first contact, and strip-like contact portions (3a to 3d) which are elongated in a fan-like shape with respect to the center of the first contact (1) are disposed in a second contact (2) and in the side opposite to the side of the first contact (1). According to this configuration and arrangement, the space for disposing the diaphragm contacts can be reduced, and the whole device can be miniaturized and lightened. Five diaphragms are shown on the printed circuit board, and five pusher portions are disposed on a core face opposed to the diaphragms and on a key base. The height of the upper, lower, right, and left pusher portions is set to be different from that of the center pusher portion.

    • An input device having an illumination function includes a wiring board having a predetermined wiring pattern thereon containing a fixed contact point, a light-emitting diode, a planar light-guide plate for guiding emission light from the light-emitting diode in a direction along a surface, a metal dome serving as a movable contact, and a cover sheet having an actuator thereon to be used to press the metal dome. The wiring board is manufactured of a white translucent material. The planar light-guide plate includes a plurality of prism grooves arranged in stripes on the surface thereof, and on a predetermined portion thereof a through-hole for housing the metal dome. An air layer is arranged between the prism bearing surface of the planar light-guide plate and the cover sheet. The metal dome 6 reflects the emission light directed within the through-hole, toward the side of the cover sheet.
