摘要： It is possible to accurately estimate the echo suppression amount for each frequency even when a nonlinear echo component is large. An estimated echo function having variables of a logarithm of a magnitude at each frequency of a reception signal, a frequency of the reception signal, a logarithm of a total reception value that is a summation of magnitudes of the reception signal or transmission of the reception signal in any frequency range, and a logarithm of an envelope of the total reception value is stored. An echo suppressing process is performed by inputting a value of a second reception signal (a result of converting the reception signal into a frequency domain) to a function representing an estimated echo to generate an echo suppressing mask, and multiplying an echo suppressing gain calculated based on this echo suppressing mask by a second transmission signal (transmission signal converted into a frequency domain).

摘要： A small-sized onboard device that includes a speaker and a microphone and is configured to reduce noise caused by an echo is provided. The speaker is provided inside a housing that forms a cavity inside so that a sound emission surface of the speaker faces a direction substantially orthogonal to a front surface, and a first opening is formed in a front surface of the housing. A microphone case and a sound guide member are juxtaposed on the front surface of the housing. A microphone is housed inside the microphone case. The microphone case has a sound pickup hole in a front surface of the microphone case. The sound guide member has a sound guide hole that passes through the sound guide member. The first opening is provided in a vicinity of a top surface or a bottom surface of the housing.

摘要： A control device calculates a first estimate value of a first monitored amount of a mobile object, from sensor information of a controlled object, using a transformed first model obtained by transformation of a first model having a multi-layered neural structure and activation functions of a ReLU structure, and predicting dynamic behavior of the mobile object. The transformed first model is a model for which weight coefficients, biases, and upper and lower limit values of input/output variables of neurons are set based on the first model and in which activation functions of the neurons are transformed using a linear inequality function having a binary variable. The control device calculates a second estimate value of a second monitored amount of the controlled object from a candidate value of an operation amount for controlling the second monitored amount. The control device determines a value of the operation amount based on a target value of the second monitored amount, the second estimate value, and the first estimate value.

摘要： There is provided an echo suppression device that allows adding a natural comfort noise even in an environment in which a change in ambient noise is large. An echo is removed from an input signal to generate an echo-removed signal, a noise signal included in the echo-removed signal is estimated to generate an estimated noise signal, and a noise signal included in the echo-removed signal is suppressed based on the estimated noise signal to generate a suppressed signal. A comfort noise is generated based on the estimated noise signal, and the comfort noise is superimposed on the suppressed signal.
