This task is focused on a natural situation when the target is an uttering person whose location is limited to a specific area. For example, the target could be a speaker who is seated in a meeting (noisy) room. Its position is distant from microphones (say more than 1 meter) and is changing due to small movements of the speaker's head. The goal is to remove typical noise (e.g. babble noise) from the recorded speech. We assume that two microphones are available.
- For such situation, a priori information may be provided in the form of noise-free recordings of the target from several (fixed) positions within the assumed area. For example, such recordings could be obtained during speaker-only intervals. How effectively can we exploit the a priori knowledge to enhance recordings of the speaker when the noise is present and his/her position is not perfectly known and could be changing within a limited area?

!! Scenario
The target is a loudspeaker that occurs within a 30x30cm area. The loudspeaker is (always) directed towards two microphones that are 2 meters distant from the center of the area. Details of the scenario are given in the following figure. @@ -Lines: 26-30 changed to +Lines: 30-34 @@
