The research project was designed to investigate by various means those kinds of information in speech which do not deal directly with the actual verbal message per se. The name given to this non-verbal information is affective information. The work attempted to make use of the physical information in the speech processing system to predict the intelligibility of the speech signal. Intelligibility as here defined is synonymous with fidelity of transmission since the subjects response is merely a repetition of the perceived input signal. With respect to affective information the goal has been to identify as far as possible the acoustical properties of the speech signal which are identified with various perceptual responses to that speech signal. The first non-verbal aspect that was considered was speech quality. Since this concept is of considerable importance both in the technology of speech processing developments and from a psychological point of view, various attempts at defining psychoacoustical correspondences have been made during the term of this project.
