摘要： A voice signal transmitting/receiving apparatus includes: a device body; a speaker array arranged in the device body and including a plurality of arrayed speaker units; and a microphone array arranged in the device body and including a plurality of arrayed microphones. By thus integrating the speaker array and the microphone array, it is possible to improve the operability of a user, to acquaint the user relatively easily with the error in the set position and to make the device compact.

摘要： A communication conference system that enables users who have only a connecting unit via a telephone line network and users who have only an IP connecting unit to hold a talk session mutually without a need of an expensive dedicated conference server is provided. A talk session device 1 includes a network processing portion for transmitting/receiving voice information to/from other equipments via IP, and a terminal for inputting/outputting a voice signal. The talk session device 1 is connected to a handset terminal of a telephone 3 via an adaptor 2 that converts the standards (mainly a level) of the voice signal. The talk session device 1 is connected to other talk session devices via IP, and is connected to other telephones by a telephone line via the telephone 3. Accordingly, a user serving as a destination of the IP and a user serving as a destination of the telephone line are connected mutually.

摘要： A control unit 7 gives acoustic environment instruction data to a picked up sound directionality control unit 5 and an adaptive filter 11. According to this, the picked up sound directionality control unit 5 generates a picked up sound signal constituted by a predetermined picked up sound directionality. The adaptive filter 11 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 13. The adaptive filter 11 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 12, the adaptive filter 11 sets a more optimum filter parameter, and generates the next pseudo echo signal.
