This has not happened. One reason for the lack of progress here was that problem complexity was seriously underestimated. Another was that appropriate protocol was not followed during system development. Appropriate standards are now available and will be reviewed. Nevertheless, there is a critical, and growing, demand for effective SI systems. This situation leads to a need for some sort of a stopgap procedure that would fill the temporary void. Fortunately, a large amount of SI research has been carried out during the cited period. Its results (which will be summarized) lead to the postulation that an aural perceptual (AP SI) system, although somewhat subjective, could be used to meet this requirement. A number of them have been developed (an example will be provided) and relevant research supports the position that, if rigorously controlled and cautiously interpreted, they can provide useful SI information. It also is recommended that, if an appropriate research model is followed, the speech/voice analysis approach should be seriously considered as a platform for the creation of digital speaker identification systems.
