Whilst research shows that talker information affects recognition of recently studied words, it remains unclear whether this information is stored in long-term memory. Three experiments explored whether talker-specificity effects (TSEs) for pseudowords changed over time and were affected by within- and between-talker variability during study. Results showed TSEs immediately after study in all experiments, consistent with episodic models, but TSEs remained a week later only for pseudowords studied in a single voice. Furthermore, source memory data suggested that talker information becomes less accessible over time, supporting hybrid models that incorporate aspects of both episodic and abstract lexical representation.
