声音之间的差异通常被大致分为“自然”和“后天”两类，这意味着有些声音是由我们的解剖学遗传决定的，而另一些声音是我们从周围的人那里模仿来的，或者是我们为了表现自己的个性而选择的。然而，通常不可能将可观察到的差异归因于一个源或另一个源，因为这两个源在实验上都是不可控制的。在同卵双胞胎的情况下，大自然提供了这样的控制。我们可以合理地假设，一对同卵双胞胎的解剖结构差异很小。如果他们的声音有差异的话，这可能是由于“学习”造成的。此外，如果这对双胞胎是在相同的环境中长大的，这可能是他们的选择，而不是直接模仿。本文对三对同卵双胞胎的/l/和/r/音素进行了研究。
The differences between voices are often broadly categorized as either 'organic' or 'learned', implying that some are determined by our anatomical inheritance, and others by what we copy from people around us or choose in order to mark our individuality. It is normally impossible, however, to assign observable differences to one source or the other, since neither source is experimentally controllable. In the case of identical twins, nature provides such a control. It can reasonably be assumed that the anatomical differences within a pair of identical twins are minimal. Differences between their voices, if any, may be attributed to 'learning' and, furthermore, if the twins have grown up in the same environment, to choices rather than to direct imitation. This paper presents a study of the /l/ and /r/ phonemes of three pairs of identical twins.
