Design outcomes

Primary

Measure	Time frame
The main study parameters are the percent correct scores for the different tests for speech perception, pitch-related speech perception and music perception. Furthermore, just-notable-differences (JND*s) for the vocal tract length and the fundamental frequency in the gender categorization task will be measured.
