    Sammanfattning : Human speech production is a complex process, involving neuromuscular control signals, the effects of articulators' biomechanical properties and acoustic wave propagation in a vocal tract tube of intricate shape. Modeling these phenomena may play an important role in advancing our understanding of the involved mechanisms, and may also have future medical applications, e. LÄS MER

    Sammanfattning : Speech perception, articulation, and word learning are three major tiers of language development in young children, integrating perceptual and productive language abilities. Infant speech perception precedes speech production and is the basis for native language learning. LÄS MER
