Abstract

See full text

Non-acoustic data from a vicinity of speech input is obtained. A subject speaker is identified as the source of the speech input from the obtained non-acoustic data by detecting mouth motion on one or more faces segmented from the non-acoustic data by comparing a first pixel intensity associated at a first time with a second pixel intensity at a second time, and selecting a face corresponding to the subject speaker from the one or more faces in response to a determination that a number of significantly changed pixels between the first pixel intensity and the second pixel intensity exceeds a threshold. A demographic is assigned to the subject speaker based on an analysis of one or more non-acoustic attributes of the subject speaker extracted from the non-acoustic data. The speech input is processed using a speech recognition system adjusted using a model selected based on the demographic.
