Abstract: An art capable of transmitting a voice separated for each speaker when voice communications are conducted in a state that a plurality of communication terminals are connected in a cascade mode is provided. When a conference is started, each participant using each terminal 10-n speaks. A voice data generation section 106 of each terminal 10-n collects the voice of each participant and generates voice data. The generated voice data is sent to a different terminal 10-n. On the other hand, the terminal 10-n determines the presence or absence of sound production for each of voice signals of a plurality of channels received from each different terminal 10-n and assigns the input channel detected to be in a sound production state to any of output channels.

Abstract: A control unit gives acoustic environment instruction data to a picked up sound directionality control unit and an adaptive filter. According to this, the picked up sound directionality control unit generates a picked up sound signal constituted by a predetermined picked up sound directionality. The adaptive filter detects the picked up sound directionality from the acoustic environment instruction data, and reads out the filter parameter corresponding to this picked up sound directionality, from a memory. The adaptive filter sets a delay coefficient and a filter coefficient of an FIR filter, and generates a pseudo echo signal by an impulse response with respect to the received sound signal. Based on an error signal obtained by subtracting the pseudo echo signal from the picked up sound signal by an adder, the adaptive filter sets a more optimum filter parameter, and generates the next pseudo echo signal.

Abstract: A karaoke network system is composed of a central station for providing a data, and a local terminal connected to the central station through a communication line; for presenting an event according to the provided data and being switchable between a working state and an idling state in response to a request. The central station responds to a call from the local terminal for providing a song data representative of a karaoke event to the local terminal through the communication line. The central station further down-loads a program data which sequentially prescribes spare events into the local terminal through the communication line. The local terminal operates in the working state where a request is present for presenting the karaoke event based on the provided song data, and otherwise operates in the idling state where a request is absent for sequentially presenting the spare events according to the down-loaded program data so as to fill a blank period of the idling state.

Abstract: A karaoke apparatus operates according to a song data for presenting a karaoke performance composed of an instrumental accompaniment and a back chorus under a designated condition determined in terms of either of a tempo and a pitch. In the karaoke apparatus, a data source provides a song data which contains a musical tone data, a synthetic voice data and a real voice data. An input panel is operated for designating either of a regular condition and an irregular condition. A tone generator processes the musical tone data to generate an instrumental accompaniment, and concurrently processes the synthetic voice data to generate a false back chorus. A voice decoder decodes the real voice data to reproduce a natural back chorus.
