LoKiS corpus
The LoKiS corpus includes acoustic recordings from a longitudinal study involving approximately 60 German-speaking children. So far, recordings have been made at five different points in time (from first to fith grade, six to eleven years old).
The corpus is being extended as part of the DFG project "The Acoustic and Perceptual Correlates of Gender in Children's Voices" (SI 743/9-1/2, project duration 2020–2028).
