Abstract
Methods and apparatus to operate an audience metering device with voice commands are described herein. In an example method, at least one of a television program audio signal or a voice command from an audience member is transduced into an audio input signal. Based on the audio input signal and a television audio line signal, a residual audio signal is generated. One or more vectors from the residual audio signal are extracted. Based on the one or more vectors extracted from the residual audio signal, the voice command is identified.
