An examination of more than sixty years of successes and failures in developing technologies that allow computers to understand human spoken language. Stanley Kubrick's 1968 film 2001: A Space Odyssey famously featured HAL, a computer with the ability to hold lengthy conversations with his fellow space travelers. More than forty years later, we have advanced computer technology that Kubrick never imagined, but we do not have computers that talk and understand speech as HAL did. Is it a failure of our technology that we have not gotten much further than an automated voice that tells us to “say or press 1”? Or is there something fundamental in human language and speech that we do not yet understand deeply enough to be able to replicate in a computer? In The Voice in the Machine, Roberto Pieraccini examines six decades of work in science and technology to develop computers that can interact with humans using speech and the industry that has arisen around the quest for these technologies. He shows that although the computers today that understand speech may not have HAL's capacity for conversation, they have capabilities that make them usable in many applications today and are on a fast track of improvement and innovation. Pieraccini describes the evolution of speech recognition and speech understanding processes from waveform methods to artificial intelligence approaches to statistical learning and modeling of human speech based on a rigorous mathematical model—specifically, Hidden Markov Models (HMM). He details the development of dialog systems, the ability to produce speech, and the process of bringing talking machines to the market. Finally, he asks a question that only the future can answer: will we end up with HAL-like computers or something completely unexpected?

A New York Times bestselling writer explores what our unique sonic signature reveals about our species, our culture, and each one of us. Finally, a vital topic that has never had its own book gets its due. There’s no shortage of books about public speaking or language or song. But until now, there has been no book about the miracle that underlies them all—the human voice itself. And there are few writers who could take on this surprisingly vast topic with more artistry and expertise than John Colapinto. Beginning with the novel—and compelling—argument that our ability to speak is what made us the planet’s dominant species, he guides us from the voice’s beginnings in lungfish millions of years ago to its culmination in the talent of Pavoratti, Martin Luther King Jr., and Beyoncé—and each of us, every day. Along the way, he shows us why the voice is the most efficient, effective means of communication ever devised: it works in all directions, in all weathers, even in the dark, and it can be calibrated to reach one other person or thousands. He reveals why speech is the single most complex and intricate activity humans can perform. He travels up the Amazon to meet the Piraha, a reclusive tribe whose singular language, more musical than any other, can help us hear how melodic principles underpin every word we utter. He heads up to Harvard to see how professional voices are helped and healed, and he ventures out on the campaign trail to see how demagogues wield their voices as weapons. As far-reaching as this book is, much of the delight of reading it lies in how intimate it feels. Everything Colapinto tells us can be tested by our own lungs and mouths and ears and brains. He shows us that, for those who pay attention, the voice is an eloquent means of communicating not only what the speaker means, but also their mood, sexual preference, age, income, even psychological and physical illness. It overstates the case only slightly to say that anyone who talks, or sings, or listens will find a rich trove of thrills in This Is the Voice.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
