Abstract : A model of the speech recognition process was presented in an attempt to find adequate measures of intelligibility and intelligence. An experiment was designed to test the model and the validity of the measures. Four trained subjects responded to distorted speech samples from a message set containing twelve single words and from a message set containing thirty-six three-word sequences. The goal was to predict the scores which would be obtained on the sequences from the scores obtained on the single words. A posteriori predictions were attempted using percentage correct measures and measures derived from information theory and a priori predictions were made from the decision theory model proposed in the study. The results of these data support the information theory and decision theory model. (Author)
