Abstract
A computing device can capture video data of at least a portion of a mouth area (e.g., mouth, lips, tongue, chin, jaw) of a user of the device. The computing device can also capture sound data including a voice of the user as well as noise (e.g. background noise). The video data can be processed to detect a movement of the portion of the mouth area. The movement of the portion of the mouth area can be analyzed and compared with mouth area movement models characteristic of oral communication (e.g., speech, song). If the movement of the portion of the mouth area corresponds to at least one model characteristic of oral communication, then the movement indicates that the user is likely engaging in oral communication. Noise reduction can be applied and/or increased on the captured sound data to reduce noise and in turn enhance the user's voice.
