This book is the first to provide detailed practical guidance for therapists in speech and language therapy with cochlear implant patients. The book includes the basics of the cochlear implant as a technical device but also provides assistance in planning the entire therapy process. In addition, comprehensive therapy materials are available to aid in planning and conducting therapy. Furthermore, interdisciplinary cooperation between surgeons, audiologists, and therapists is of great importance. Therefore, the book explores possibilities for constructive exchanges between these disciplines. Due to the multifaceted view of the topic, this book is not only interesting for therapists but also for all individuals working with people with profound hearing impairments. The basis of English translation of this book, originally in German, was facilitated by artificial intelligence. The content was later revised by the authors for accuracy.
