Computational approaches to phonology have gained in popularity in recent years. These approaches use models to formalize hypotheses about how people learn aspects of sound structure, or to investigate basic principles about how sound systems are organized. The Northeast Computational Phonology Workshop (NECPhon) is an informal gathering of scholars interested in any aspect of computational phonology. Our goal is to provide a relaxed atmosphere where researchers can share their latest work. This is the sixth annual NECPhon, and the first time the workshop has been held at the University of Maryland.
