Fig 3. Generalizing talker identity across source mechanisms.
Listeners learned talker identity successfully from both laryngeal (LV) and electrolarynx (EL) vocal sources, but were unable to generalize talker identity to the untrained mechanism. After learning talker identity from one source mechanism, listeners performed no better than chance at identifying the same talkers using the other mechanism, regardless of whether sentence content was familiar (darker boxes) or novel (lighter boxes). Figure conventions as in Figure 2.
