The book gives an overview of telephone interpretation from a professional, innovative and pedagogical approach. There are not many studies on telephone interpretation, as this technique was first introduced in the twentieth century. Nevertheless, it is becoming very popular due to its effectiveness: it is an excellent option for situations that cannot be planned in advance (for instance, emergency services), it is provided immediately and it is available 24/7, it relies on readily available everyday technology (mobile telephones) and it decreases the cost of the interpretation services. Due to these advantages, many interpreters and students are interested in becoming specialists. This book is unique in its perspective and contributors. It was written by specialists who are involved fist-hand in the study and practice of telephone interpretation: pioneers and successful companies providing the service, researchers who are carrying out state-of-the-art investigations, telephone interpreters who describe their day-to-day work; and university lecturers, who provide academic and pedagogical approaches by designing lessons and hypothetical cases for students to practice.
