Abstract: We exploit the properties of the third-order spectra in two proposals to obtain speech detection functions. One is obtained from the principal domain of the bispectrum and the other one from the integrated bispectrum. We have developed a threshold-based system in which the detection functions can be easily integrated, Experiments show the improvement on the detection scores over the energy-based function in noisy environments.
