Abstract
A system for detecting a voice signal includes: a first integrator for receiving an input signal and for providing a first integrator output signal, wherein the first integrator includes a first attack time; a second integrator for receiving the input signal and for providing a second integrator output signal, the second integrator including a second attack time that is substantially slower than the first attack time; and a comparator configured for receiving the first and second integrator output signals and for providing a comparator output signal indicating detection of a voice signal when the first integrator output signal exceeds the second integrator output signal by at least a threshold amount.
