Abstract : A facility for quantifying the speech intelligibility of voice communication systems using the Diagnostic Rhyme Test has operated continuously at the Acoustics Laboratory of the Royal Signals and Radar Establishment since February 1985. User acceptability trials that enable Service personnel to operate, and then assess, voice communication systems under simulated operational conditions have also been conducted. This report describes the procedures used to assess both intelligibility and acceptability, and presents the results of studies investigating the use of digital vocoders in high noise environments. An Executive Summary is provided to give project offices and others responsible for designing, specifying or procuring voice communications systems (and components) an indication of the services that are available.
