- Abstract
Cockpits of the aircrafts, especially those propeller-driven and the interior of a broad range of ground combat platforms, especially tracked ones, are characterized by high amplitude low frequency noise. This noise is coming from the engine and is interfering with communication. Since command and control in critical combat mission is a key to mission success, high speech intelligibility is the basic requirement in practice. A broad range of digital techniques and algorithms exists today which can be used and implemented either in personal headsets or in vehicular communications harness to increase the speech quality. However, these digital techniques and algorithms can have influence on the intelligibility of the processed speech. For this reason, digital algortihms must be assessed from intelligibility point of view, since high intelligibility is a crucial and basic requirement. This article is focused on the methods which are suitable for the evaluation of intelligibility of the processed speech and for the assessment of speech enhancement algorithms. Various methods which can be used for the assessment of speech enhancement algorithms from this point of view are described here.
