A transgender person does not identify with their biological sex and may seek to live in the opposite gender role. Through voice and speech, we receive essential information about a person, which makes the voice a secondary sexual characteristic. Voice therapists can help transgender individuals achieve a modification of their speech and voice, thereby making it easier for them to live in their desired gender. In addition to basic information on the topic of transgender identity, the book provides insights into gender-specific voice and communication parameters, relevant therapeutic components, goals, and possible exercises in voice therapy. It serves as a well-founded source of information for transgender individuals and their relatives, offering food for thought regarding one's own voice and communication patterns.
