Psychoacoustic Assessment of Speech Communication Systems. The Diagnostic Discrimination Test,
Abstract
The report traces the rationale, development and experimental evaluation of the Diagnostic Discrimination Test (DDT). The DDT is a three-choice test of consonant discriminability. Specifically, it is a test of the discriminability of the perceptual/acoustic dimensions of consonant phonemes within specific vowel contexts. The DDT was created and developed in an attempt to provide a diagnostic assessment of communication system deficiencies to aid in system design and development. Results are presented in terms of the sensitivity of the DDT to various degrees of speech impoverishment, and of the reliability of the DDT upon successive experimental replications. (Author)
