This state-of-the-art volume covers recent developments in research on audio description, the professional practice dedicated to making audiovisual products, artistic artefacts and performances accessible to those with supplementary visual and cognitive needs. Harnessing the power of the spoken word, the projects covered in this book illustrate the value of audiovisual content descriptions not only in relation to the role of breaking down physical, cognitive and emotional barriers to entertainment, but also in informing broader media practices such as video archive retrieval, video gaming development and application software creation. The first section maps out the field, discusses key concepts in relation to new developments and illustrates their application; the second part focuses on new audiences for AD, whilst the third part covers the impact of new technologies. Throughout this book contributors focus on methodological innovation, regarding audio description as an opportunity to engage in multi-dimensional linguistic and user-experience analysis, as it intersects with and contributes to a range of other research disciplines. This book is key reading for researchers, advanced students and practitioners of audiovisual translation, media, film and performance studies, as well as those in related fields including cognition, narratology, computer vision and artificial intelligence.
