British English, American English, Antarctic English: How Do Accents Develop?

A group of British researchers spent months alone on the isolated continent of Antarctica.

There, an acoustic analysis was made of their speech characteristics as individuals.

In a matter of months, changes were observed.

The acoustical study created a computational model based partially on a common accent in Antarctica to predict the phonetic changes they expected to hear from this group’s prolonged isolation.

Recorded productions of the participating individuals were then taken and compared to the model.

In some ways, the model predicted the phonetic changes in the individuals’ accents.

Published in The Journal of the Acoustical Society of America, the results suggest that the initial stages of phonetic changes in accent occur incrementally when individuals in isolation interact.

Let’s delve deeper into this example of how accents and phonetics develop across the same language.

Shared Spoken Idiosyncrasies

Defining a spoken accent as “shared spoken idiosyncrasies across a community of speakers,” the study touches upon theories regarding potential evolutionary reasoning behind the development of accents.

Some evolutionists theorize that, due to its difficulty in imitation by outsiders, the function of an accent can allow the in-group to identify imposters, while simultaneously breeding cooperation, coordination, and camaraderie amongst individuals with the same accent.

Children are more apt at developing accents than adults, because the phonetic specifications are highly dependent on precise timing and vocal organ coordination, which is more easily acquired at a younger age.

How Accents Form

In this study, communication density was identified as the primary catalyst for accent formation.

This means that who you talk to and how often you talk to them can influence the early stages of accent formation.

The Antarctic researchers’ unique position of isolation created an environment resembling a microcosm of a former colonial settlement.

There was little-to-no communication with outside groups and yet regular communication with each other.

Being inside this bubble amplified the results.

BrainStuff’s Laurie L. Dove notes that the two primary factors influencing accent are isolation and human nature.

Dove writes,

“Human nature, vague as it sounds, simply refers to our innate love of being in groups. When a human is part of a crowd, they identify membership by wearing certain styles of clothing or eating specific foods. That group of people also may speak a certain way — so distinctly so that an accent becomes part of the group’s identity.”

What else impacts accent formation?

Next week, we’ll talk about social class, migration, and invasion.
