Keynote Speech: The role of input in the acquisition of L2 stops
Tutorial Lecture: Historical overview of the VOT dimension in L2 speech research
James Emil Flege is Professor Emeritus in the School of Health Professions at the University of Alabama at Birmingham. His research focused on the production and perception of phonetic segments cross-linguistically, in monolinguals, and in the two languages of bilinguals differing in age of L2 learning (early vs. late), years of L2 use, and frequency of L2 use.
This NIH-sponsored research led to the formulation of the Speech Learning Model. The SLM posits that despite evidence for what appears to be age-related limits on speech learning ability, the processes and mechanisms that make “perfect” L1 acquisition possible remain intact across the life span and available for later L2 speech learning.
According to the SLM: (1) Fine-grained differences in the phonetic implementation of sounds found in two languages remain detectable by learners of all ages; (2) The primary reasons for less-than-perfect L2 learning is the gradual maturation of L1 categories through childhood, and substantial differences between most L1 and L2 learners in the quality and quantity of input received; (3) Learners of all ages retain the capacity to establish new categories based on information regarding phonetic segments derived while using an L2. The likelihood of a category being formed for an L2 sound is hypothesized to depend on the state of development of a learner’s L1 phonetic categories when L2 learning begin, the perceived phonetic dissimilarity of the L2 sound from the closest L1 sound, and the quantity/quality of L2 phonetic input received.
Professor Carol Stoel-Gammon
University of Washington, USA
Keynote Speech: Crosslinguistic investigations of phonological development: The search for universal patterns
Tutorial Lecture: Early phonological development: Qualitative patterns and quantitative measures
Dr. Carol Stoel-Gammon received her Ph.D. in Linguistics from Stanford University (Palo Alto, California) in 1974. She has spent most of her professional career in the Department of Speech and Hearing Sciences at the University of Washington (Seattle, USA); she is now a Professor Emerita in the department. Other teaching positions include the State University of Campinas, Brazil; the University of Colorado; the University of Calgary, Canada; the University of Alberta, Canada; and the University of Canterbury, Christchurch, New Zealand.
Professor Stoel-Gammon’s research interests include prelinguistic and early linguistic development; cross-linguistic studies of phonological acquisition; early identiﬁcation of speech and language disorders; phonological acquisition in children with speech and language disorders; relationships between phonological and lexical acquisition; phonological acquisition in bilingual children; and effects of hearing loss on phonological development. She has published over 150 research articles and book chapters, and is the co-author of two books: Normal and Disordered Phonology in Children (with C. Dunn) and Assessing Prelinguistic and Early Linguistic Behaviors in Developmentally Young Children (with Olswang, Coggins, & Carpenter) and a co-editor of: Phonological Development: Models, Research, Implications (with Ferguson & Menn) and Promoting Language and Literacy Development in Children Who Are Deaf and Hard of Hearing (with Moeller & Ertmer).
Professor Tatsuya Kawahara

Keynote Speech: Modelling difficulties of second language learners using speech technology
Tutorial Lecture: Computer-Assisted Language Learning (CALL) using speech technology
Tatsuya Kawahara received B.E. in 1987, M.E. in 1989, and Ph.D. in 1995, all in information science, from Kyoto University, Kyoto, Japan. From 1995 to 1996, he was a Visiting Researcher at Bell Laboratories, Murray Hill, NJ, USA. Currently, he is a Professor in the School of Informatics, Kyoto University. He has also been an Invited Researcher at ATR and NICT.
He has published more than 300 technical papers on speech recognition, spoken language processing, and spoken dialogue systems. He has been conducting several projects including speech recognition software Julius, the automatic transcription system deployed in the Japanese Parliament (Diet), and an autonomous android Erica.
He was a General Chair of IEEE Automatic Speech Recognition and Understanding workshop (ASRU 2007). He also served as a Tutorial Chair of INTERSPEECH 2010 and a Local Arrangement Chair of ICASSP 2012. He is an editorial board member of Elsevier Journal of Computer Speech and Language, APSIPA Transactions on Signal and Information Processing, and IEEE/ACM Transactions on Audio, Speech, and Language Processing. He is a Fellow of IEEE.
