Speech discrimination requires five distinct auditory features

Evidence

The hearing system is a very important sensory organ for us humans. It is a receiver of sound information that, together with our speech producing system, enables us to participate in acoustical communication. Therefore the ability of hearing-impaired patients to discriminate speech is one of the important aspects to be measured quantitatively in clinical audiology. There are five fundamental features that are necessary in order to discriminate speech: sensitivity, frequency selectivity, amplitude discrimination, temporal resolution and information processing. To avoid serious social handicaps, the five features have to be good enough to discriminate and understand speech. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1868
