Providing an in-depth discussion of emoji use in a global context, this volume presents the use of emoji as a hugely important facet of computer-mediated communication, leading author Jieun Kiaer to coin the term 'emoji speak'. Exploring why and how emojis are born, and the different ways in which people use them, this book highlights the diversity of emoji speak. Presenting the results of empirical investigations with participants of British, Belgian, Chinese, French, Japanese, Jordanian, Korean, Singaporean, and Spanish backgrounds, it raises important questions around the complexity of emoji use.Though emojis have become ubiquitous, their interpretation can be more challenging. What is humorous in one region, for example, might be considered inappropriate or insulting in another. Whilst emoji use can speed up our communication, we might also question whether they convey our emotions sufficiently. Moreover, far from belonging to the youth, people of all ages now use emoji speak, prompting Kiaer to consider the future of our communication in an increasingly digital world.
