Abstract:
The evaluation of voice communications systems has traditionally been done by articulation testing using a team of listeners. Although this method is conceptually straightforward it can be time consuming, and there are a number of variables which must be controlled for consistent results. Consequently, electronic evaluation promises savings in time and money if it can be shown to have results equivalent to articulation tests. One electronic evaluation method, the Voice Interference Analysis Set manufactured by General Electronic Laboratories, Inc. was tested to determine if it produced results equivalent to articulation tests. In the laboratory, tones, noise, and pulse interference were mixed in an audio channel and the electronic results compared with articulation tests conducted under similar conditions. Then the results from a field teshich both an electronic evaluation and an articulation test had been run on a voice communication system were analyzed for corre lation between the two evaluations. On the basis of these tests, it is concluded that electronic evaluation of voice communications systems is possible subject to certain restric tions. Furthermore, certain theoretical and practical limitations of the Voice Interference Analysis Set are discussed. Author
