Abstract
Five members of the IAVI‐examined spectrographically and aurally pairs of samples corresponding to (1) mimicked voice‐real voice, (2) mimicked voice‐mimicked voice, and (3) real voice‐real voice, to decide whether or not the two components of the pair belonged to the same or different persons. There were two types of recordings; one type obtained in a quiet environment, the other within an ambient noise environment. Results suggest that there is no significant spectrographic intraspeaker variability within the mimicked voices produced by the particular professional mimic employed in this experiment. However, the examiners found significant interspeaker variation between the real voice of each mimicked person and its mimicked voice by the mimic, variation that allowed them to produce right discriminations. In all cases, average fundamental frequencies differed. The recordings including noise yielded less significant results than the ones obtained in quiet. In addition, these pairs of voices were presented to nontrained listeners aurally only, in a free field, requesting them to decide whether or not the two voices of each pair were the same or different. They produced right answers in approximately 75% of the tests.
