What is the term for difficulty speaking due to an obstruction of air in the nose or throat?

The term for difficulty speaking due to an obstruction of air in the nose or throat is "Voice Disorders." This classification pertains specifically to issues that affect the voice itself, often involving the vocal cords, larynx, or resonance. When there is an obstruction in the nasal passages or throat, it can disrupt the normal modulation and quality of the voice, leading to challenges in producing sound clearly and effectively.

Voice disorders encompass a range of conditions that influence the pitch, volume, and quality of the voice. This is distinct from fluency disorders, which typically relate to the flow of speech (such as stuttering), articulation difficulties that focus on the clarity of speech sounds, and broader speech and language communication disorders that incorporate various aspects of speech and language development and processing. By understanding these distinctions, one can better identify and address the specific nature of speech issues related to physical obstructions in the vocal tract.
