The Arizona Child Acoustic Database is a longitudinal collection of audio samples from children between the ages of 2-7 years. The long-range goal of this project is to provide new insight into the physical mechanisms of vocal sound production during a critical period of growth and development. These data are being used to inform our efforts of building a model of speech production for child talkers.
