一个令人惊讶的不同之处是证明了美国和标准的英国南部英语的发言者对近似的看法。18名受试者（6名AE和12名SSBE）进行了一项识别任务，其中他们判断刺激是否更像/r/或/w/。刺激包括五个声音，从源/r/复制合成，其中F2和F3的值被调整为落在[“turned r”]和[w]的典型频率之间。两个方言组的表现之间唯一的显着差异发生在一个标记中，其中F3处于典型的/r/频率，F2降低到/w/频率。AE和SSBE使用者分别有90%和59%的时间将这个标记识别为/r/。这是出乎意料的，因为两种方言中的/r/都以低F3为特征。然而，这种差异可能是由于SSBE中/r/的“唇齿”变体的存在。由于这种变体没有低F3，SSBE扬声器必须比AE扬声器容忍更广泛的/r/-类型。因此，SSBE中的/r/范畴可能越来越多地由F2而不是F3定义，这也对这种重音中的/r/的未来产生了影响
A surprising dissimilarity is attested in the perception of approximants by speakers of American and Standard Southern British English. Eighteen subjects (6 AE and 12 SSBE) performed an identification task in which they judged whether stimuli were more like /r/ or /w/. The stimuli comprised five sounds, copy‐synthesised from a source /r/, where the values of F2 and F3 we adjusted to fall between the frequencies typical for ["turned r"] and [w]. The only significant difference between the two dialect groups' performance occurred with a token in which F3 was at a frequency typical for /r/ and F2 was lowered to that of /w/. AE and SSBE speakers identified this token as /r/ 90% and 59% of the time, respectively. This is unexpected as /r/ in both dialects is characterised by a low F3. However, the difference may be due to the existence of the 'labiodental' variant of /r/ in SSBE. As this variant does not have a low F3, SSBE speakers must tolerate a wider diversity of /r/‐types than AE speakers. Therefore, the /r/ category in SSBE may be becoming increasingly defined by F2, rather than F3, which also has implications for the future production of /r/ in this accent
