摘要： An audio signal produced by playing a plurality of musical instruments is separated into sound sources according to respective instrument sounds. Each time a separation process is performed, the updated model parameter estimation/storage section 114 estimates parameters respectively contained in updated model parameters such that updated power spectrograms gradually change from a state close to initial power spectrograms to a state close to a plurality of power spectrograms most recently stored in a power spectrogram separation/storage section. Respective sections including the power spectrogram separation/storage section 112 and an updated distribution function computation/storage section 118 repeatedly perform process operations until the updated power spectrograms change from the state close to the initial power spectrograms to the state close to the plurality of power spectrograms most recently stored in the power spectrogram separation/storage section 112. The final updated power spectrograms are close to the power spectrograms of single tones of one musical instrument contained in the input audio signal formed to contain harmonic and inharmonic models.

摘要： An ultra-directional speaker having a modulator 33 for modulating an ultrasonic carrier signal with an input electric signal from an audible sound signal source, and an emitter 44 for emitting an output of the modulator 33 is mounted in a moving object 1 having a target tracking system for sensing a target in a surrounding space in real time using the above-mentioned emitter 44. The moving object equipped with ultra-directional speaker can therefore transmit a voice only to a specific target through parametric action caused by the nonlinearity of finite amplitude of ultrasonic wave.

摘要： A robot auditory apparatus and system are disclosed which are made capable of attaining active perception upon collecting a sound from an external target with no influence received from noises generated interior of the robot such as those emitted from the robot driving elements. The apparatus and system are for a robot having a noise generating source in its interior, and include: a sound insulating cladding (14) with which at least a portion of the robot is covered; at least two outer microphones (16 and 16) disposed outside of the cladding (14) for collecting an external sound primarily; at least one inner microphone (17) disposed inside of the cladding (14) for primarily collecting noises from the noise generating source in the robot interior; a processing section (23, 24) responsive to signals from the outer and inner microphones (16 and 16; and 17) for canceling from respective sound signals from the outer microphones (16 and 16), noises signal from the interior noise generating source and then issuing a left and a right sound signal; and a directional information extracting section (27) responsive to the left and right sound signals from the processing section (23, 24) for determining the direction from which the external sound is emitted. The processing section (23, 24) is adapted to detect burst noises owing to the noise generating source from a signal from the at least one inner microphone (17) for removing signal portions from the sound signals for bands containing the burst noises.
