A description is given of the evaluation of a simulated suppression system performing ideal suppression of a jammer signal, given the voicing states (voiced, unvoiced, silent) of the target and jammer speech as a function of time and the isolated target and jammer speech waveforms. By applying suppression to select regions of jammer speech as a function of the voicing states of the target and jammer, and by measuring the intelligibility of the resulting jammer-suppressed cochannel speech, it is possible to identify those regions of cochannel speech on which interference suppression most improves intelligibility. Such results can help focus algorithm development efforts.
