Abstract : |
This paper deals with the use of linear microphone arrays for detection, localization and enhancement of a generic acoustic message produced in a noisy environment. A CrosspowerSpectrum Phase based analysis and a Coherence Measure representation are presented, that allow an accurate time delay estimation employed for the acoustic source position hypothesis. Preliminary results in terms of source localization accuracy are given. Once source position is estimated, an enhanced version of the original acoustic message is derived, that can represent the input for a speech recognition system., |
