What are the three major resonating cavities in speech?

The three major resonating cavities in speech are correctly identified as the nasal, oral, and pharyngeal cavities. These cavities play crucial roles in shaping the sound produced during speech and contribute to the unique resonance qualities of an individual's voice.

The nasal cavity is essential for producing nasal sounds, such as /m/, /n/, and /ŋ/, where airflow passes through the nose. The oral cavity, being the largest of the three, is vital for the articulation of various speech sounds, including vowels and consonants, by modifying the shape and configuration as the tongue, lips, and palate adjust during sound production. The pharyngeal cavity connects the oral and nasal cavities to the larynx and is involved in resonating the sound before it exits through the mouth and nose.

While other options mention organs or cavities associated with speech, they do not focus on the primary cavities responsible for resonance in speech production. For instance, the lungs are crucial for providing air pressure necessary for phonation, while the esophageal cavity is not involved in sound resonance during normal speech. Similarly, the trachea serves as an airway but does not function as a resonating cavity. The larynx is involved in sound production rather than resonance. Understanding the roles
