A book on how formants behave in acoustic tubes. An initial step in relating vowel acoustics to vowel articulation.

This collection examines the promise and limitations for computer-assisted language learning of emerging speech technologies: speech recognition, text-to-speech synthesis, and acoustic visualization. Using pioneering research from contributors based in the US and Europe, this volume illustrates the uses of each technology for learning languages, the problems entailed in their use, and the solutions evolving in both technology and instructional design. To illuminate where these technologies stand on the path from research toward practice, the book chapters are organized to reflect five stages in the maturation of learning technologies: basic research, analysis of learners’ needs, adaptation of technologies to meet needs, development of prototypes to incorporate adapted technologies, and evaluation of prototypes. The volume demonstrates the progress in employing each class of speech technology while pointing up the effort that remains for effective, reliable application to language learning.

Traditionally, investigations into speech and pronounciation have relied on the unaided skills of the phonetician in recognising and reproducing speech sounds. But many practicioners are now using instruments to gain a greater understanding of speech and to be able to analyse speech patterns in situations when speaking and hearing would otherwise be inaccessible without the use of these instruments. This new book looks at how this form of investigation has developed, and considers the types of data that can be used and which questions can be solved using experimental phonetics.

Getting Great Sounds: The Microphone Book imparts microphone tips and tricks of the pros to make them available to any sound engineer or home studio enthusiast. It explains aspects of all kinds of microphones, how they work, and how to use them in session recording. A well-known recording engineer with decades of industry experience, Tom Lubin presents technical information in a friendly, straightforward, and easy-to-grasp way, based on real-life experiences. This third edition includes a review of key practices at the end of chapters and a new section that provides an overview of microphone manufacturers you may not have heard of. There are now over one hundred and fifty companies making microphones for studio applications of one form or another, and most are small companies owned by people who are passionate about good sound. These companies feature high quality microphones, and many use classic designs with more affordable prices. How to choose and use microphones was once a skill passed down from senior sound engineers to their assistants as they would listen and learn by observation. Today, few large studios have assistant engineers, and an overwhelming number of studios are operated by their owners who are often self-taught and lack the benefit of the big-studio tutelage. This book is your guide to understanding the ins and outs of microphones and music studio production.

Bringing together the knowledge of world experts on different aspects of primate auditory function, this book bridges the epistemological gap between primate ethologists and auditory neurobiologists. Leading ethologists, comparative psychologists, and neuroscientists who have developed new experimental approaches apply their methods to a variety of issues dealing with primate vocal behavior and the neurobiology of the primate auditory system. The synthesis of ethological and neurobiological approaches to primate vocal behavior presented in this book will yield a rich understanding of the acoustic and neural bases of primate audition and shed light on the evolutionary precursors to speech.

A landmark history of early radio in Germany and the quest for broadcast fidelity When we turn on a radio or stream a playlist, we can usually recognize the instrument we hear, whether it’s a cello, a guitar, or an operatic voice. Such fidelity was not always true of radio. Broadcasting Fidelity shows how the problem of broadcast fidelity pushed German scientists beyond the traditional bounds of their disciplines and led to the creation of one of the most important electronic instruments of the twentieth century. In the early days of radio, acoustical distortions made it hard for even the most discerning musical ears to differentiate instruments and voices. The physicists and engineers of interwar Germany, with the assistance of leading composers and musicians, tackled this daunting technical challenge. Research led to the invention in 1930 of the trautonium, an early electronic instrument capable of imitating the timbres of numerous acoustical instruments and generating novel sounds for many musical genres. Myles Jackson charts the broader political and artistic trajectories of this instrument, tracing how it was embraced by the Nazis and subsequently used to subvert Nazi aesthetics after the war and describing how Alfred Hitchcock commissioned a later version of the trautonium to provide the sounds of birds squawking and flapping their wings in his 1963 thriller The Birds. A splendid work of scholarship by an acclaimed historian of science, Broadcasting Fidelity reveals how the interplay of science, technology, politics, and culture gave rise to new aesthetic concepts, innovative musical genres, and the modern discipline of electroacoustics.

This book provides state-of-the-art coverage of research in laboratory phonology. Laboratory phonology denotes a research perspective, not a specific theory: it represents a broad community of scholars dedicated to bringing interdisciplinary experimental approaches and methods to bear on how spoken language is structured, learned and used; it draws on a wide range of tools and concepts from cognitive and natural sciences. This book describes the investigative approaches,disciplinary perspectives, and methods deployed in laboratory phonology, and highlights the most promising areas of current research.Part one introduces the history, nature, and aims of laboratory phonology. The remaining four parts cover central issues in research done within this perspective, as well as methodological resources used for investigating these issues. Contributions to this volume address how laboratory phonology approaches have provided insight into human speech and language structure and how theoretical questions and methodologies are intertwined. This Handbook, the first specifically dedicated tothe laboratory phonology approach, builds on the foundation of knowledge amassed in linguistics, speech research and allied disciplines. With the varied interdisciplinary contributions collected, the Handbook advances work in this vibrant field.
