Imagine the scene: you are sitting on the tube and on gets someone you instinctively feel is American. To make sure you ask them the time and fight, but how did you know?

A. When we say someone ‘looks American’, we take into consideration dress, mannerism, and physical appearance. However, since the Americans do not constitute one single race, what exactly is meant by ‘look’? In fact, one salient feature is a pronounced widening around the jaw – a well-documented phenomenon. Writer Arthur Koestler once remarked that friends of his, whom he had met thirty years after they’ emigrated to the United States, had acquired an ‘American physiognomy’, i.e. a broadened jaw, an appearance which is also prevalent in the indigenous population. An anthropologist friend of his attributed this to the increased use of the jaw musculature in American enunciation. This ‘change of countenance’ in immigrants had already been observed by the historian M. Fishberg in 1910.

B. To paraphrase the philosopher Emerson, certain national, social and religious groups, such as ageing actors, long-term convicts and celibate priests, to give just a few examples, develop a distinguishing ‘look’, which is not easily defined, but readily recognized. Their way of life affects their facial expression and physical features, giving the mistaken impression that these traits are of hereditary or ‘racial’ origin. All the factors mentioned above contribute, as well as heredity. But the question of appearance being affected by pronunciation – as in the case of American immigrants including those from other English speaking countries over the course of many years – is of great interest, and calls for further study into the science of voice production. This can only benefit those working in the field of speech therapy, elocution and the pronunciation of foreign languages, and help the student from a purely physiological point of view. Naturally, the numerous psychological and socio-linguistic factors that inhibit most adult learners of foreign languages from acquiring ‘good’ pronunciation constitute a completely different and no less important issue that requires a separate investigation.

C. The pronunciation of the various forms of English around the world today is affected by the voice being ‘placed’ indifferent, parts of the mouth. We use our Speech organs in certain ways to produce specific sounds, and these muscles have to practice to learn new phonemes. Non-Americans should look in the mirror while repeating ‘I really never heard of poor reward for valour’ with full use of tile USA retroflex/phoneme, and note what happens to their jawbones after three or four repetitions. Imagine the effect of these movements on the jaw muscles after twenty years! This phoneme is one of the most noticeable features of US English and one that non-Americans always exaggerate when mimicking the accent. Likewise, standard British RP is often parodied, and its whine of superiority mocked to the point of turning the end of one’s nose up as much as possible. Not only does this enhance the ‘performance’, but also begs the question of whether this look is the origin of the expression ‘stuck up’?

D. Once on a Birmingham bus, a friend pointed to a fellow passenger and said, ‘That man’s Brummie accent is written all over his face.’ This was from someone who would not normally make crass generalizations. The interesting thing would be to establish whether thin lips and a tense, prominent chin are a result of the way Midlands English is spoken, or its cause, or a mixture of both. Similarly, in the case of Liverpool, one could ask whether the distinctive ‘Scouse accent was a reason for or the frequency of high cheekbones in the local population.

E. When one learns another accent, as in the theatre, for example, voice coaches often resort to images to help their students acquire the distinctive sound of the target pronunciation. With ‘Scouse’, the mental aid employed is pushing your cheekbones up in a smile as high as they will go and you have got a very slack mouth full of cotton wool. The sound seems to spring off the sides of your face-outwards and upwards. For a Belfast accent, one has to tighten the sides of the jaws until there is maximum tension, and speak opening the lips as little as possible, This gives rise to the well-known ‘Ulster jaw’ phenomenon. Learning Australian involves imagining the ordeals of the first westerners transported to the other side of the world. When exposed to the merciless glare and unremitting heat of the southern sun, we instinctively screw up our eyes and grimace for protection.

F. Has this contributed to an Australian ‘look’, and affected the way ‘Aussies’ speak English or vice versa? It is a curious chicken and egg conundrum, but perhaps the answer is ultimately irrelevant. Of course, other factors affect the way people look and sound, and it would certainly be inaccurate to suggest that all those who speak one form of a language or dialect have a set physiognomy because of their pronunciation patterns. But a large enough number do, and that alone is worth investigating. What is important, however, is establishing pronunciation as one of the factors that determine physiognomy, and gaining a deeper insight into the origins and nature of the sounds of speech And of course, one wonders what ‘look’ one’s own group has!
