Abstract: A voice processing device includes plural microphones arranged so as to correspond to a plurality of positions. The voice processing device includes at least one memory that stores instructions and voice signals from the plural microphones, and a processor. The voice signals collected by the plural microphones, respectively, during a prescribed period before a present time, are repeatedly stored in the at least one memory as buffered voice signals. The processor detects whether a prescribed word is uttered by a speaker based on the voice signals collected by the plural microphones, determines a microphone corresponding to the speaker by referring to the buffered voice signals, and suppresses the voice signals collected by the plural microphones other than the microphone corresponding to the speaker.

The processor is coupled to the memory, and, when executing a program stored in the memory, performs: receiving a first voice that is a voice uttered by a first speaker; determining whether or not a position of the first speaker can be identified; and outputting, to a target device, a voice command that is specified by a voice and is a signal for controlling the target device, the processor limiting output of a speaker position command related to a position of a speaker among the voice command in a case where the processor determines that the position of the first speaker cannot be identified.

Abstract: An audio processing system includes at least one first microphone, at least one adaptive filter, and a processor. The at least one first microphone acquires a first audio signal and outputs a first signal based on the first audio signal. The first audio signal includes at least one of a first audio component generated at a first position and a second audio component generated at a second position different from the first position. The first signal is input to the at least one adaptive filter. The at least one adaptive filter outputs a passing signal based on the first signal. The processor, when executing a program stored in a memory, performs: making a determination of which of the first audio component and the second audio component the first audio signal includes more; and controlling a filter coefficient of the adaptive filter based on a result of the determination.

Abstract: An audio processing system includes: a first microphone configured to output a first signal based on a first audio signal; one or more microphones each of which outputs a microphone signal based on an audio signal; one or more adaptive filters configured to respectively receive the microphone signals from the one or more microphones and output passing signals based on the microphone signals; and a processor configured to: determine whether the microphone signal includes uncorrelated noise; control one or more filter coefficients of the one or more adaptive filters; and subtract a subtraction signal based on the passing signals from the first signal. The one or more microphones include a second microphone that outputs a second signal. When determining that the second signal includes the uncorrelated noise, the processor is configured to set a level of the second signal input to the corresponding adaptive filter to zero.

Abstract: An active noise reduction device includes a standard signal generator, adaptive filters, a control sound emitter, and an error signal detector. The standard signal generator generates a standard signal including harmonics of a fundamental frequency correlated with the control target sound. The adaptive filters each generates corresponding one of harmonic components of a control signal based on the standard signal. The adaptive filters each is for corresponding one of the harmonics. The control sound emitter emits a control sound based on the control signal. The error signal detector collects residual noise left over after interference between the control target sound and the control sound, and detects an error signal based on the residual noise. Each of the adaptive filters includes a step size determiner. The step size determiner sets the step size parameter based on a frequency variation in the corresponding one of the harmonic components of the standard signal.

Abstract: An active noise reduction device includes a standard signal generator, an adaptive filter unit, a control sound output unit, and an error signal detector. The adaptive filter unit includes a control signal generator, a filter coefficient update unit, and a step size setting unit. The control signal generator multiplies a standard signal by a filter coefficient to generate a control signal. Based on a reference signal and an error signal, the filter coefficient update unit updates the filter coefficient so as to minimize the error signal. The step size determiner sets a step size parameter indicating an update amount of the filter coefficient. The filter coefficient update unit sets a step size adjustment coefficient for adjusting the step size parameter based on an audio information feature amount and a change of the control signal.
