摘要

An ensemble sound source direction estimation method and apparatus based on deep neural network for robust sound source direction estimation are proposed. An ensemble sound source direction estimation method based on a deep neural network according to an embodiment includes extracting a feature vector from speech data of a reverberation environment; Estimating a reverberation environment probability according to the reverberation environment of the speech data; Generating an ensemble sound source direction estimation model by combining a plurality of deep neural networks in a pre-learned reverberation environment with an ensemble by using a weighted average method based on the estimated reverberation environment probability; And estimating a sound source direction based on the ensemble sound source direction estimation model.
