The Influence of First and Second Formants on the Intelligibility of Clipped Speech
Experiments are described which show that speech from which information concerning all but one formant has been suppressed prior to infinite amplitude clipping is either highly intelligible or virtually unintelligible, depending on whether second or first formant information has been selected for preservation. Conclusions reached from these findings are used to account for the results of earlier experiments on the intelligibility of various forms of amplitude- and frequency-distorted speech.
