This study is to see if discriminability of English vowels by native Japanese speakers can be predicted based on what Perceptual Assimilation Model (=PAM) (Best 1995) states. Native Japanese speakers served as subjects in the following four experiments ; discrimination experiment identification experiment, perceptual assimilation experiment, production experiment. Native English speakers participated as the control group in the discrimination and identification experiments.The results of the series of experiments do not necessarily support what PAM states, but the results indicate Japanese speakers' perception of English vowels is affected by their L1 vowel categories. /ae/ is often perceptually assimilated to Japanese low vowel /a/, and is misidentified with /a/ and /∧/, which are both perceptually assimilated to the Japanese low vowel /a/, but when a velar stop precedes, /ae/ is perceptually assimilated to /ja/, which apparently makes it easier for Japanese subjects to differentiate … More /ae/ from /a/ or /∧/ in this consonantal context. The perception of /ae/ is also strongly affected by the following consonant: when /n/ follows, it is perceptually assimilated to /ea/ because formants bend in /ae/ in /CVn/ contexts, which apparently facilitates better discrimination of /a/ from /a/ or /∧/. The manner of articulation of the following consonant influences Japanese speakers' perception and production of English vowels: percent correct identification and discrimination are lower when a nasal (/n/) or a liquid (/l/) follows than when a stop (/t/ or /d/). Percent correct identification of /i/ is especially low when /l/ follows, and the intelligibility of the /i/ tokens produced by Japanese speakers is also low in this consonantal context. This is probably because there is no equivalent phone to the postvocalic /l/ in Japanese. This may be an indication that the ease to perceive and produce surrounding consonants can influence the perception and production of non-native vowels. Less

这项研究的目的是看看是否可以根据感知同化模型 (=PAM)（Best 1995）的规定来预测以日语为母语的人对英语元音的辨别能力。以日语为母语的人作为以下四个实验的受试者；辨别实验、识别实验、知觉同化实验、生产实验。以英语为母语的人作为对照组参与了辨别和识别实验。这一系列实验的结果并不一定支持 PAM 的说法，但结果表明日本人对英语元音的感知受到他们的 L1 元音类别的影响。 /ae/ 经常在感知上同化为日语低元音 /a/，并且被误认为是 /a/ 和 /∧/，这两个词在感知上都同化为日语低元音 /a/，但是当软腭塞音在前时，/ae/ 会​​在感知上同化为 /ja/，这显然使日语受试者更容易区分……更多 /ae/ 与 /a/ 或 /∧/ 在此 辅音上下文。 /ae/ 的感知也受到以下辅音的强烈影响：当 /n/ 跟随时，它在感知上被同化为 /ea/，因为在 /CVn/ 上下文中，共振峰在 /ae/ 中弯曲，这显然有助于更好地区分 /a/ 与 /a/ 或 /∧/。以下辅音的发音方式会影响日本人对英语元音的感知和发音：鼻音 (/n/) 或流音 (/l/) 跟随时的正确识别和辨别百分比低于塞音 (/t/ 或 /d/) 时的正确率。当 /l/ 跟在后面时，/i/ 的正确识别百分比特别低，并且在这种辅音上下文中，日语使用者产生的 /i/ 记号的可理解性也很低。这可能是因为日语中没有与后元音 /l/ 等效的音素。这可能表明感知和产生周围辅音的难易程度会影响非母语元音的感知和产生。较少的
