Recognition memory for consonants and vowels selected from within and between phonetic categories was examined in a delayed comparison discrimination task. Accuracy of discrimination for synthetic vowels selected from both within and between categories was inversely related to the magnitude of the comparison interval. In contrast, discrimination of synthetic stop consonants remained relatively stable both within and between categories. The results indicate that differences in discrimination between consonants and vowels are primarily due to the differential availability of auditory short-term memory for the acoustic cues distinguishing these two classes of speech sounds. The findings provide evidence for distinct auditory and phonetic memory codes in speech perception.
在一项延迟比较辨别任务中,研究了从语音类别内部和之间选择的辅音和元音的识别记忆。从类别内部和之间选择的合成元音的辨别准确率与比较间隔的大小呈负相关。相比之下,合成塞音在类别内部和之间的辨别保持相对稳定。结果表明,辅音和元音之间辨别的差异主要是由于区分这两类语音的声学线索在听觉短期记忆中的可用性不同。这些发现为语音感知中不同的听觉和语音记忆编码提供了证据。
