Abstract:

The application of digital voice communication systems for military usage has been hampered by the lack of reliable predictions of system voice quality and acceptability. Although intelligibility tests have proved useful to system designers and have provided lower limits to system acceptability, there has been no simple method for rank ordering voice processors operating in a given transmission environment with respect to voice quality. A method for rank ordering which is useful for up to about ten systems and gives reliable results is described in this report along with a typical system evaluation at NRL. This evaluation shows the ability of the test to rank order systems under simulated transmission conditions. It should be noted that adding a new system to a previous ranking with this method is difficult and may require rerunning the entire test.
