What are the two subcategories of Voice Disorders?

Voice disorders can be categorized into two main subcategories: phonation disorders and resonance disorders. Phonation disorders refer to issues with the production of sound due to difficulties with vocal cord function, which can result in problems such as breathiness, harshness, or hoarseness of the voice. These occur when there is something wrong with how the vocal cords vibrate, leading to improper sound generation.

On the other hand, resonance disorders involve issues with how sound is shaped within the vocal tract after it is produced by the vocal cords. This can result in an abnormal quality of voice, often described as being too nasal or not nasal enough, which affects the overall clarity and richness of vocal output.

Together, these two categories help professionals understand and classify the various difficulties individuals may experience with their voice, enabling them to provide targeted interventions and support.
