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., . “Consonant identification in N-talker babble is a nonmonotonic function of N,” J. Acoust. Soc. Am. >118, 2775–2778; . “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.

Am。“在各种背景竞争者中的单词识别性能”。学院音频> 8 ，71–80]，但是对多说话者ba语的研究很少采用目标语言以外的其他语言的背景ba语。为了确定背景语音的不利影响是由于语言内容还是语音掩蔽器的声学特性引起的，本研究评估了当背景噪声的语言与该语言相同或不同时的语音噪声识别目标语音。重复先前的发现，结果表明，无论说话者所说的语言如何，母语为英语的英语听众在六语者和二语者中的英语句子识别能力较差。此外，我们的结果表明，在两个说话者的bble语中，英语ba语对母语为英语的听众的影响要大于普通话对ba语的不利影响。这些发现证明了“语言干扰”形式的信息在句子中的掩盖。此干扰是否处于语言结构的词汇，次词汇和/或韵律级别，以及是否受目标语言和噪声语言之间的语音相似性所调制。
