DIVA Model (Directions Into Velocities of Articulators)

The DIVA Model (Directions Into Velocities of Articulators) is a scientific framework explaining how the brain controls speech production. It suggests that the brain plans speech sounds by sending precise instructions to the muscles that move your lips, tongue, and other articulators. These instructions are based on auditory targets (how the sounds should sound) and motor commands (how to produce those sounds). The model emphasizes learning and feedback, meaning the brain constantly compares the produced speech with intended sounds and adjusts movements for accuracy. It helps researchers understand normal speech and disorders affecting speech production.
