Stimulus sample discrimination SSD is an objective psychophysical procedure, in which samples are drawn from various signal distributions for comparison and an index of discrimination is measured. A key feature of SSD is the use of samples from a context distribution, which act either as additional or as distracting sources of information with respect to the discrimination task. When the context distribution provides information about the natural variations in the sounds from a musical instrument, SSD may prove useful as a measure of the perceptual accuracy of a sound synthesis algorithm. We report on results from a study in which SSD is applied to measure the degree to which singer identity is preserved in loworder synthesis of the female singers.
