对不同背景噪音下的语音感知的研究表明，包含语言内容的噪音对听者的影响不同于非语言噪音[例如，Simpson， S. A.和Cooke， M.(2005)]。“N-口语体的辅音识别是N的非单调函数，”J. Acoust。Soc。Am. 118,2775 -2778；斯佩里，j.l.，威利，t.l.，和席尔，m.r.（1997）。在不同背景竞争对手中的单词识别性能。但很少有多语者在目标语以外的语言中使用背景语的研究。为了确定背景语音的不利影响是由于语言内容还是由于语音掩蔽器的声学特性，本研究评估了背景噪声的语言与目标语音的语言相同或不同时的噪声语音识别。与之前的研究结果相同，研究结果显示，无论是哪种语言，母语为英语的听者在听六语宝宝的英语句子时的识别能力都不如听两语宝宝的英语句子。此外，我们的研究结果表明，在两语者的牙牙学语中，母语为英语的听者受到英语牙牙学语的不利影响要大于普通话牙牙学语的不利影响。这些发现证明了以“语言干扰”的形式对噪声中句子识别的信息掩蔽。这种干扰是否发生在语言结构的词汇、亚词汇和/或韵律层面，以及是否受到目标语言和噪声语言之间语音相似性的调节，仍有待确定。(c) 2007年美国声学学会。
Studies of speech perception in various types of background noise have shown that noise with linguistic content affects listeners differently than nonlinguistic noise [e.g., Simpson, S. A., and Cooke, M. (2005). "Consonant identification in N-talker babble is a nonmonotonic function of N," J. Acoust. Soc. Am. 118, 2775-2778; Sperry, J. L., Wiley, T. L., and Chial, M. R. (1997). "Word recognition performance in various background competitors," J. Am. Acad. Audiol. 8, 71-80] but few studies of multi-talker babble have employed background babble in languages other than the target speech language. To determine whether the adverse effect of background speech is due to the linguistic content or to the acoustic characteristics of the speech masker, this study assessed speech-in-noise recognition when the language of the background noise was either the same or different from the language of the target speech. Replicating previous findings, results showed poorer English sentence recognition by native English listeners in six-talker babble than in two-talker babble, regardless of the language of the babble. In addition, our results showed that in two-talker babble, native English listeners were more adversely affected by English babble than by Mandarin Chinese babble. These findings demonstrate informational masking on sentence-in-noise recognition in the form of "linguistic interference." Whether this interference is at the lexical, sublexical, and/or prosodic levels of linguistic structure and whether it is modulated by the phonetic similarity between the target and noise languages remains to be determined.
