MULTICHANNEL MICROPHONE-BASED REVERBERATION TIME ESTIMATION METHOD AND DEVICE WHICH USE DEEP NEURAL NETWORK

摘要

A multichannel microphone-based reverberation time estimation method and device which use a deep neural network (DNN) are disclosed. A multichannel microphone-based reverberation time estimation method using a DNN, according to one embodiment, comprises the steps of: receiving a voice signal through a multichannel microphone; deriving a feature vector including spatial information by using the inputted voice signal; and estimating the degree of reverberation by applying the feature vector to the DNN.
