"Mehmet Yavaş has brought together a formidable team of scholars of phonological acquisition in this collection. Between them they have produced a ground-breaking volume on atypical phonology. This not only describes a wide range of unusual patterns but it informs our understanding of the nature of the phonological component itself."

--Martin J. Ball, Linköping University, Sweden

"In Unusual Productions in Phonology, internationally known experts present a new and unique examination of non-ambient phonology from multiple perspectives of typical and atypical children and second language learners. This volume is a welcome and much-needed addition to the literature."

--Brian A. Goldstein, La Salle University, Philadelphia, PA, USA

"Phonological acquisition—is it guided by universal principles or language-specific features? This volume, a 'must read' for those interested in child phonology, includes contributions from renowned researchers who present multiple theoretical perspectives and data from a diverse set of languages."

--Carol Stoel-Gammon, University of Washington, Seattle, USA
