Abstract: An endpoint deployed in a room may analyze a video output of a video camera disposed within the room for an image of a microphone disposed within the room. Based on the analyzing, the endpoint may then detect the image of the microphone within the video output of the video camera. The endpoint may then determine if the microphone is receiving speech from an active speaking participant, who may be one of the one or more participants that are disposed within the room. In the event the microphone is receiving speech from the active speaking participant, the endpoint may then display on a video display the video output of the video camera that has been altered to show a framing of the active speaking participant.

Abstract: An acoustic transformation system and method. A specific embodiment is the transformation of acoustic speech signals produced by speakers with speech disabilities in order to make those utterances more intelligible to typical listeners. These modifications include the correction of tempo or rhythm, the adjustment of formant frequencies in sonorants, the removal of adjustment of aberrant voicing, the deletion of phoneme insertion errors, and the replacement of erroneously dropped phonemes. These methods may also be applied to general correction of musical or acoustic sequences.
