16. A hardware computer-readable storage device comprising instructions stored thereon that are executable by a computing device to: receive speech recognition data as an output from a speech recognition stage of an audio processing pipeline, the speech recognition stage being configured to compare inputs received from a digital audio processing stage of the audio processing pipeline to a plurality of recognized speech patterns to recognize speech inputs, and the speech recognition data comprising a recognized speech segment and confidence data comprising a recognition confidence value that represents a confidence in a certainty of a match of the recognized speech segment to a speech pattern; receive acoustic locational data as an output from a digital audio processing stage of the audio processing pipeline, the acoustic locational data related to a location of origin of the recognized speech segment as determined via signals from a microphone array; receive image data comprising visual locational information related to a location of each person located in a field of view of a depth-sensing camera; compare the acoustic locational data to the visual locational data to determine whether the recognized speech segment originated from a person in the field of view of an image sensor; adjust the confidence data based upon whether the recognized speech segment is determined to have originated from a person in the field of view of the depth-sensing camera; if it is determined that the recognized speech segment originated from a person in the field of view of the image sensor, then determine whether a face of the person is facing the image sensor; and adjusting the confidence data such that the recognition confidence value has a lower value after adjusting if the face of the person is not facing the image sensor than if the face of the person is facing the image sensor.
