title: [The voice of the child, morphological evolution of the larynx and its acoustic consequences].
abstract: From a review of the literature, the authors analyze the role of laryngeal modifications in the evolution of a child's voice. The modifications found are topographic (laryngeal descent in the neck), morphologic (increase in volume modification of laryngeal shape), and histologic (lamina propria differentiation), each responsible for acoustic modifications. The chronological evolution of the voice integrates these modifications in a global context of development, where the central nervous system is of primary importance.
