Pitch changes in the vocal tone

"pitch changes in the voice result directly from the action of the larynx. Five factors are involved, namely, (1) the length, (2) weight or mass, and (3) tension of the vocal folds, (4) their elasticity, and (5) the sub-glottal breath pressure. The first three of these are essentially the properties of the vibrating string. The longer and heavier the string, the lower the resulting pitch will be; the tighter the string, the higher the pitch will be."

Virgil Anderson.

Pitch and length are inversely related.
