1. A method for determining a biometric parameter associated with a subject, the method comprising:
receiving a first signal obtained using a first sensor, the first sensor comprising a microphone disposed on an earpiece of an audio device, wherein the first sensor is used to estimate the biometric parameter within a degree of confidence;
determining a signal-to-noise ratio (SNR) of first signal is less than a threshold value for determining the biometric parameter;
signaling a second sensor to receive a second signal upon determining the SNR is less than the threshold, the second sensor being disposed on the audio device, wherein the second sensor is used to estimate the biometric parameter when the first sensor is unable to estimate the biometric parameter within the degree of confidence;
determining the biometric parameter based, at least in part, on the second signal; and
estimating when the subject falls asleep using the biometric parameter.
