METHODS AND APPARATUS TO OPERATE AN AUDIENCE METERING DEVICE WITH VOICE COMMANDS
First Claim
1. A method to identify audience members based on voice, the method comprising:
- obtaining an audio input signal including a program audio signal and a human voice signal;
receiving an audio line signal from an audio output line of a monitored media device;
processing the audio line signal with a filter having adaptive weights to generate a delayed and attenuated line signal;
subtracting the delayed and attenuated line signal from the audio input signal to develop a residual audio signal;
identifying a person that spoke to create the human voice signal based on the residual audio signal; and
logging an identity of the person as an audience member.

Abstract
Methods and apparatus to operate an audience metering device with voice commands are described herein. An example method to identify audience members based on voice, includes: obtaining an audio input signal including a program audio signal and a human voice signal; receiving an audio line signal from an audio output line of a monitored media device; processing the audio line signal with a filter having adaptive weights to generate a delayed and attenuated line signal; subtracting the delayed and attenuated line signal from the audio input signal to develop a residual audio signal; identifying a person that spoke to create the human voice signal based on the residual audio signal; and logging an identity of the person as an audience member.

15. A machine accessible medium storing instructions, which when executed, cause a machine to:
-
obtain an audio input signal including a program audio signal and a human voice signal;
receive an audio line signal from an audio output line of a monitored media device;
process the audio line signal with a filter having adaptive weights to generate a delayed and attenuated line signal;
subtract the delayed and attenuated line signal from the audio input signal to develop a residual audio signal;
identify a person that spoke to create the human voice signal based on the residual audio signal; and
log an identity of the person as an audience member.

16. An audience measurement device to identify audience members based on voice, the device comprising:
-
a transducer to obtain an audio input signal including a program audio signal and a human voice signal;
a filter having adaptive weights to receive an audio line signal from an audio output line of a monitored media device, and to process the audio line signal to generate a delayed and attenuated line signal;
a difference detector to subtract the delayed and attenuated line signal from the audio input signal to develop a residual audio signal;
an identification device to identify a person that spoke to create the human voice signal based on the residual audio signal; and
a memory to log an identity of the person as an audience member. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
