While reverberation often degrades speech intelligibility, previous studies have shown that prior exposure to reverberation can reduce its adverse effects on speech perception. The current study investigated the effect of prior exposure to reverberation on the perception of nonnative speech sounds. We compared the results from two experiments, one in “blocked presentation” where the target words with the same amount of reverberation were presented to participants consistently, and another in “random presentation” where the amount of reverberation added to the target words changed between each trial. A Japanese minimal pair,/ie/ ‘house’ -/iie/ ‘no’, where vowel length creates a phonemic difference, was used as the target. The results for native listeners showed that their responses did not differ significantly between the blocked and random presentations. On the other hand, the effect of presentation type was significant in terms of the responses from the nonnative listeners. The results showed that nonnative listeners did not respond differently between the anechoic and reverberant conditions in the blocked presentation. However, there was a significant difference between the anechoic and reverberant conditions in the random presentation. The results from the nonnative listeners suggest that they try to obtain information of reverberation from the exposure since they could not use top-down processing effectively as much as native listeners.

虽然混响通常会降低语音清晰度，但之前的研究表明，事先接触混响可以减少其对语音感知的不利影响。当前的研究调查了先前接触混响对非母语语音感知的影响。我们比较了两个实验的结果，一个是在“阻塞呈现”中，将具有相同混响量的目标词始终呈现给参与者，而另一个在“随机呈现”中，添加到目标词的混响量在每个实验之间发生变化。审判。日语最小对，/ie/ 'house' -/iie/ 'no'，其中元音长度产生音位差异，被用作目标。本地听众的结果表明，他们的反应在屏蔽和随机演示之间没有显着差异。另一方面，就非母语听众的反应而言，呈现类型的影响是显着的。结果表明，非本地听众在阻塞演示中的无回声和混响条件之间没有不同的反应。然而，随机呈现的消声和混响条件之间存在显着差异。非母语听众的结果表明他们试图从曝光中获取混响信息，因为他们不能像母语听众那样有效地使用自上而下的处理。就非母语听众的反应而言，演示类型的影响是显着的。结果表明，非本地听众在阻塞演示中的无回声和混响条件之间没有不同的反应。然而，随机呈现的消声和混响条件之间存在显着差异。非母语听众的结果表明他们试图从曝光中获取混响信息，因为他们不能像母语听众那样有效地使用自上而下的处理。就非母语听众的反应而言，演示类型的影响是显着的。结果表明，非本地听众在阻塞演示中的无回声和混响条件之间没有不同的反应。然而，随机呈现的消声和混响条件之间存在显着差异。非母语听众的结果表明他们试图从曝光中获取混响信息，因为他们不能像母语听众那样有效地使用自上而下的处理。
