  This paper introduces to a special session on nasalization at the XVIth ICPhS. Nasal studies have a long history, at the interface between phonetics and phonology. Nasal processes are best accounted for by considering the phonetic constraints acting on the production and the perception of nasal sounds, as well as the nasal phonological patterns in the world’s languages. Alternately, nasal studies improve our general understanding of phonetic and phonological processes. The three invited papers of the session are presented and discussed in this framework.
Nasalization-2 Nasals and nasalization: the relation between segmental and coarticulatory timing
Patrice Speeter Beddor, University of Michigan
Paper File
  Cross-language acoustic and perceptual studies in our lab test the hypothesis that certain aspects of variation in the temporal extent of vowel nasalization are linked to concomitant, inversely related variation in the duration of a flanking nasal consonant. Data from English, Thai, and Ikalanga are reported that support this hypothesis, and phonological phenomena consistent with the observed patterns of variation are considered.
Nasalization-3 Investigating the aerodynamics of nasalized fricatives
Ryan K. Shosted, University of Illinois, Urbana-Champaign
Paper File
  Nasalized oral fricatives do not exist in phonemic opposition to oral fricatives in any language of the world. It has been claimed that nasalized fricatives cannot exist phonetically; however, numerous grammatical descriptions suggest otherwise. This claim is addressed by measuring the presence of nasal airflow during the production of various anterior fricatives in conditions of coarticulatory nasalization. If nasal exhalation is taken as the definition of nasalization, then nasalized fricatives are shown to occur in speech. The potential acoustic and perceptual consequences of nasal flow during oral fricatives are discussed.
Nasalization-4 Compatibility of features and phonetic content. The case of nasalization
Maria-Josep Solé, Universitat Autònoma de Barcelona
Paper File
  This paper reviews data on the compatibility of nasalization with manner and voicing features. First, it addresses the relations between nasalization and manner features and discusses the scales of nasalization spreading in the light of aerodynamic and acoustic factors. Second, it examines the interdependent relations between voicing and nasality. These observations lead to propose disfavoured sequences involving nasals. The paper argues that aerodynamic and acoustic interactions between features determine their likelihood to combine within segments and when segments follow each other.
Nasalization-5 Moving phonological science from paper to the laboratory: the case of nasals and nasalization
John J. Ohala, University of California, Berkeley
Paper File
  The three papers in this session illustrate dramatically how far phonological science has evolved over the past few centuries. The behavior of speech sounds, in this instance, nasals, which previously could only be described or notated in a variety of ways, is now explained by reference to physical principles from anatomy, physiology, and acoustics, and perception.
Nasalization-6 Coarticulatory timing and aerodynamics of nasals and nasalization
Didier Demolin, Universidade de São Paulo & Université libre de Bruxelles
Paper File
  This paper discusses Beddor, Shosted and Solé papers that deal with the relation between segmental and coarticulatory timing for nasals and nasalization; the aerodynamics of nasalized fricatives and the compatibility and phonetic content of features in the case of nasalization. Three points are discussed: (i) the hypothesis of a constant size of velum gesture; (ii) nasalized fricatives and (iii) nasalization in manner features and voicing.
