Resonance disorders can occur due to:

Resonance disorders can arise from a range of causes, which is why the option indicating both structural and functional causes is accurate. Structural causes can include anatomical abnormalities such as a cleft palate or vocal fold issues that physically alter the airflow and sound quality during speech. On the other hand, functional causes may involve the way speech is produced or learned, which can include specific patterns of articulation that affect how sound resonates in the vocal tract.

Understanding resonance disorders is essential for speech-language pathologists and assistants, as effective assessment and treatment require grasping these diverse influences. The recognition that both structural and functional factors can contribute to resonance disorders informs a more comprehensive approach in both diagnosis and intervention, allowing for tailored strategies that address the individual needs of clients.
