    Abstract: Techniques are provided for reverberation compensation for far-field speaker recognition. A methodology implementing the techniques according to an embodiment includes receiving an authentication audio signal associated with speech of a user and extracting features from the authentication audio signal. The method also includes scoring results of application of one or more speaker models to the extracted features. Each of the speaker models is trained based on a training audio signal processed by a reverberation simulator to simulate selected far-field environmental effects to be associated with that speaker model. The method further includes selecting one of the speaker models, based on the score, and mapping the selected speaker model to a known speaker identification or label that is associated with the user.

    Abstract: Techniques are provided for video summarization, based on speaker segmentation and clustering, to identify persons and scenes of interest. A methodology implementing the techniques according to an embodiment includes extracting audio content from a video stream and detecting one or more segments of the audio content that include the voice of a single speaker. The method also includes grouping the one or more detected segments into an audio cluster associated with the single speaker and providing a portion of the audio cluster to a user. The method further includes receiving an indication from the user that the single speaker is a person of interest. Segments of interest are then extracted from the video stream, where each segment of interest is associated with a scene that includes the person of interest. The extracted segments of interest are then combined into a summarization video.
