Effects of Stimulus Duration and Type on Perception of Female and Male Speaker Age
Susanne Schötz · Lund University Publications (Lund University) · 2005
Our abilitiy to estimate speaker age was investigated with respect to stimulus duration and type as well as speaker gender in four listening tests with the same 24 speakers, but with four different types of stimuli (ten and three seconds of spontaneous speech, one isolated word and six concatenated isolated words). Results showed that the listeners' judgements were about twice as accurate as chance, and that stimulus duration and type affected the judgements. Moreover, stimulus duration affected the listeners’ judgments of female speakers somewhat more, while stimulus type affected the judgments of male speakers more, indicating that listeners may use different strategies when judging female and male speaker age.
