1. A method for measuring speech intelligibility, the method comprising the steps of: inputting a speech waveform; extracting at least one acoustic feature from the waveform; segmenting at least one phoneme from the at least one first acoustic feature; extracting at least one acoustic correlate measure from the at least one phoneme; determining at least one intelligibility measure, wherein the determination is based upon a language; and mapping the at least one acoustic correlate measure to the at least one intelligibility measure, wherein mapping comprises a vector of at least one value that correspond to the at least one intelligibility measure, the at least one value corresponding to a degree to which the at least one intelligibility measure corresponds to the at least one phoneme.
