Abstract
Disclosed herein are method, systems, and computer-program products for segmenting a binaural recording of speech into parts containing self-speech and parts containing external speech, and processing each category with different settings, to obtain an enhanced overall presentation. The segmentation is based on a combination of: i) feature-based frame-by-frame classification, and ii) detecting dissimilarity by statistical methods. The segmentation information is then used by a speech enhancement chain, where independent settings are used to process the self- and external speech parts.
