This book was born from the need to unify terminology in speech therapy especially in the area of voice where different professionals (such as singing teachers doctors actors and speech therapists) converge each with their own technical language inherited or based on outdated literature. The lack of consensus hinders interdisciplinary communication affecting diagnosis treatment and research. The work seeks to standardize concepts to serve as an academic and clinical reference promoting a common basis for artistic practice accurate diagnosis and scientific research.The voice as an artistic and scientific phenomenon requires a multidisciplinary approach that combines individual expression with anatomical and physiological knowledge. A uniform terminology improves communication between professionals avoiding misunderstandings and ensuring coordinated and quality care. This consensus is essential to advance research education and clinical practice in the field of vocal health.
