OBJECTIVE MEASUREMENT OF VOICE CHANNEL INTELLIGIBILITY

Following the results of a feasibility study (Hartman and Boll, 1976) an objective intelligibility measure is developed using a large data base consisting of 8-50 word phonetically balanced word groups with twelve different kinds of distortion. Justification for the use of this particular measure is included, with mathematical derivations and physical interpretations. A discussion of the feasibility of a hardware implementation of the software developed here is also included. (Author)
