Two recordings identified by a letter (A or B) were made in each case. Mixtures were then generated by adding a speech signal to the background noise signal. For the reverberant environments -+Su+- and -+Ca+-, the speech signals were recorded in an office room using the same microphone pair. For the outdoor environment -+Sq+-, the speech signals were mixed anechoically through simulation. The distance between the sound source and the array centroid was 1.0 m for female speech and 0.8 m for male speech. The direction of arrival (DOA) of the speech source was different in each mixture and the signal-to-noise ratio (SNR) was drawn randomly between -17 and +12 dB.
