Preliminaries to analysis of quality in speech communication

In this study we first give our reason for introducing confusion of timbre-signal in speech-communication technology. We consider treatment of this point more important for our introduction than an ordinary quality treatment applied, for example, to articulation- and loudness-rating of communication systems. Then we proceed to analyse the mechanism of quality judgement in the confusion test carried out as our experimental study. In our judging we clarify two processes, those of identification and discrimination, the former associated directly with similarity and the latter with dissimilarity in timbre judgement. By introducing a concept of direction in confusion, we endeavor to derive from these two processes of judgement (identification and discrimination) the two confusion modes (incoming and outgoing) and to use them as the best available tool by which to dispose of confusion. Next, we stress the point that in speech-communication engineering we must advance our confusion study along a radical line – that of duality of quality; in other words, we must proceed not only with the confusion in phonemic aspect but also with the confusion in vocal aspect. The first is readily available for articulation transmission and the second for naturalness transmission either in telephonic blind communication or in broadcasting of speech programs by radio where, in the majority of cases, the aim of transmission is to transfer emotional information involved with speech and not to restrict the transference of intellectual information expressed by speech.
