Main advantages:
- high quality of articulation (minimum speech distortion);
- suppression of non-stationary noise;
- fast adaptation;
- using of the cheap electret microphones.
Technology was tested in real condition with using of electret microphones with uni-direction diagram, distance between microphones is 0.05 - 0.07 meter, distance to source of the speech is 0.7 meter.
