采用连续识别记忆实验研究口语单词的识别记忆。独立变量是一个单词的初始和后续呈现之间的中间单词数（滞后），刺激集中说话者的总数，以及单词是否以相同的声音或不同的声音重复。在实验1中，识别判断仅基于单词同一性。在所有滞后值和说话人变异性的水平上，同音重复比异音重复识别得更快、更准确。在实验2中，识别判断同时基于单词身份和语音身份。实验对象非常准确地识别出重复的声音。说话者的性别影响语音识别，但不影响物品识别。这些结果表明，说话者声音的详细信息被保留在口头单词的长期情景记忆表征中。
Recognition memory for spoken words was investigated with a continuous recognition memory task. Independent variables were number of intervening words (lag) between initial and subsequent presentations of a word, total number of talkers in the stimulus set, and whether words were repeated in the same voice or a different voice. In Experiment 1, recognition judgments were based on word identity alone. Same-voice repetitions were recognized more quickly and accurately than different-voice repetitions at all values of lag and at all levels of talker variability. In Experiment 2, recognition judgments were based on both word identity and voice identity. Subjects recognized repeated voices quite accurately. Gender of the talker affected voice recognition but not item recognition. These results suggest that detailed information about a talker's voice is retained in long-term episodic memory representations of spoken words.
