9. A non-transitory computer readable medium having software that improves a speech intelligibility and speech quality that models a speech segment based on a detected background comprising: a modeling logic that represents the background noise detected from an input signal comprising a desired signal and a plurality of undesired signals; a signal-to-noise logic that approximate a signal-to-noise ratio of at least one of the signals that comprise the input signal; an articulation logic that approximates an articulation index of the at least one of the signals that is processed by the signal-to-noise processor; and shaping logic that adjusts the spectrum of the speech segment to improve an intelligibility and quality of the speech segment, wherein the articulation index measures the intelligibility of the speech segment, and the shaping logic adjusts the spectrum of the speech segment based on a comparison of the articulation index to a plurality of predetermined thresholds.
