This document discusses the key speech organs needed to produce spoken language. It identifies the lips, teeth, tongue, alveolar ridge, hard palate, soft palate, uvula, and glottis as the main speech organs. The lips, teeth, and different parts of the tongue are involved in forming consonant sounds, while the alveolar ridge, hard palate, and tongue help produce sounds like /t/, /d/, and /j/. The soft palate and uvula work with the throat and lungs to create guttural sounds, and the vocal folds and glottis enable voicing and sounds like /h/ when they vibrate.
