Abstract

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.

在不同说话人数的多人咿呀学语中识别英语元音a)。

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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
