摘要： A speech communication apparatus of the present invention includes, in addition to an echo canceller for canceling an acoustic echo generated in a hands-free speech space, a chirp signal generating unit and a training unit. The chirp signal generating unit generates a chirp signal adequate for initial training of the echo canceller. The training control unit enables the chirp signal generating unit to generate a chirp signal, when a predetermined condition for starting hands-free speaking is satisfied, and a chirp tone corresponding to the chirp signal to be output as a volume-amplified tone from the hands-free speaker. The echo canceller performs initial training of the echo canceller based on the chirp tone.

摘要： A radiotelephone of this invention comprises a sending-speech level varying circuit for varying the level of the sending-speech signal from the microphone and supplying the resulting signal and receiving-speech level varying means for varying the level of the receiving-speech signal demodulated by receiving means and supplying the resulting signal to the speaker, as well as a talking-mode setting section and a gain control circuit. At the talking-mode setting section, either the handset talking mode or the hand-free talking mode is set. At the gain control circuit, the gains of the sending-speech level varying circuit and receiving-speech level varying circuit undergo variable control according to the talking mode set by the talking-mode setting section. The gain control is carried out in such a manner that the gain becomes a first specific value when the handset talking mode has been set, and a second specific value larger than the first value when the hand-free talking mode has been set.

摘要： A cordless telephone system includes a base unit connected to both a subscriber line and at least one branch telephone, and a mobile unit capable of being coupled to the base unit over a radio link. In the event that the handset of a branch telephone is switched on after a speech communication link has been established between the mobile unit and the subscriber line, an alarm may be provided to the user of the mobile unit. In addition, the user of the mobile unit may place the system in a holding state after a speech communication link has been established whereby the base unit and mobile unit maintain the speech communication link, but the mouthpiece of the mobile unit is disabled. In the event that the handset of a branch telephone is switched on, while the system is in a holding state, an alarm signal may be generated and output to a loud speaker at the mobile unit, and the mobile unit may be released from its holding state.

摘要： A main body controller provided in an image forming apparatus receives a VDP job from an external computer, and arranges image data of a reusable object and a variable object, which correspond to the VDP job, on a page for printout. An inspection controller performs inspection processing for printed matter for each page, and the main body controller preferentially stores image data of the reusable object, which corresponds to the page for which the printing has been determined to be defective as a result of inspection processing, in a cache unit. The main body controller acquires the reusable object, which corresponds to the page for which the printing has been determined to be defective, from the cache unit, and executes page reprint processing using the acquired reusable object.
