!::Two-channel noisy recordings of a moving speaker within a limited area::
+
+ !! Motivation + 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 the limited area? + + !! Results + The results are available [http://www.onn.nii.ac.jp/sisec13/evaluation_result/MOV/MOV2013.htm|here] !! Scenario @@ -Lines: 22-26 changed to +Lines: 30-34 @@
