Recent studies have shown that ability to recognize an imitated voice is affected by topic and familiarity with the person being imitated. The signal detection methods used in those studies give no specific information about the distribution of non matching positive responses (false alarms) amongst voices used as distracters (foils). This paper shows that there was a selective listener preference for Foil 4. However, preliminary comparison of Foil 4 with the target imitated voice has not revealed conclusively any similarities in speech features that account for listeners’ preferential selection.
