Direction of arrival estimation for indoor environments based on acoustic composition model with a single microphone

作者：

Highlights：

• This paper presents an effective method for multiple talker localisation using only a single microphone in a room.

• In this study, we estimate the acoustic transfer function from reverberant speech, using clean speech model.

• We process the speech signal in the cepstrum domain, and propose Composite Reverberant Speech (CRS) model and Direct Training Reverberant Speech (DTRS) model to obtain reverberant speech model.
