A method of enhancing the intelligibility of speech sounds in a communications headset, includes: detecting an incoming signal with speech content; based upon detectable parameters in the incoming signal, determining a combination of signal processing parameters including a high pass cutoff frequency value and a low pass cutoff frequency value for a filtering function, and an expander threshold level, an expander attack time, and an expander release time for an expander function; and sequentially applying the filtering function and expander function to the incoming signal so that the degraded sound quality of the incoming signal may be modified real-time to increase intelligibility as variations occur in speech sound quality of the incoming signal.
