摘要

本研究考察了 20 名听力正常、母语为英语的成年听者在多人咿呀学语(MTBs)中对英语元音的识别能力。在由 1、2、4、6、8、10 和 12 个说话者(说话者人数 [N])以及信噪比为 -12、-6 和 0 dB 的语音状噪声组成的 MTB 中,呈现了嵌入 h-V-d 结构的 12 个元音。结果表明,当信噪比较低时,元音识别率与 N 呈非单调函数关系。MTB 对元音识别的掩蔽效应与辅音识别最为相似,但与之前研究中报告的单词和句子识别的掩蔽效应则不太相似。

English vowel recognition in multi-talker babbles mixed with different numbers of talkersa).
The present study examined English vowel recognition in multi-talker babbles (MTBs) in 20 normal-hearing, native-English-speaking adult listeners. Twelve vowels, embedded in the h-V-d structure, were presented in MTBs consisting of 1, 2, 4, 6, 8, 10, and 12 talkers (numbers of talkers [N]) and a speech-shaped noise at signal-to-noise ratios of -12, -6, and 0 dB. Results showed that vowel recognition performance was a non-monotonic function of N when signal-to-noise ratios were less favorable. The masking effects of MTBs on vowel recognition were most similar to consonant recognition but less so to word and sentence recognition reported in previous studies.
