THIS IS THE VOICE

An expert popular science account of human speech.

In his latest, New Yorker staff writer Colapinto provides an intensely researched, tightly focused, lucidly written story that is long but not too long. As the author points out, to call human speech a “miraculous feat” understates the case. All other animals “use their voices to make in-the-now proclamations about immediate survival and reproductive concerns, including expressions of fear, anger, hunger and mating urges.” Evolved perhaps 200,000 years ago, human language allows us to refer to events in the past or future and to make plans that we share with others, “to build the villages, towns, cities and nations that have given us primacy over the Planet and everything on it.” Even before birth, infants listen, their brains absorbing a dazzling array of tone, phonetics, syntax, patterns, and rules. Despite what early experts taught, language is not pre-installed in the brain at birth; babies learn it, usually accumulating a “mental dictionary” of 60,000 words by age 18. They achieve this because words are not random assemblages of digits. They carry meaning, and we are a species that craves meaning. Midway through the book, Colapinto moves from the mechanism of speech to its purpose. Darwin compared the changes languages undergo to natural selection, but the author disagrees. Over time, he maintains, changes in articulation, accent, and vocabulary have not increased but hobbled their efficiency, creating a Babel of incomprehensible tongues that pushes us apart. Observers claimed that the spread of media, from radio to the internet, would homogenize American speech, but the opposite occurred. Instant communication has combined with bitter ideological, economic, and cultural clashes to accelerate the creation of new American speech patterns. In the final chapter, Colapinto discusses political oratory, which has united Americans in the past. He gives high marks to the rhetoric of presidents such as Lincoln, Kennedy, and Reagan; however, like the majority of Americans, he considers Trump a divisive force.

A rich trove of science and contemporary culture.
