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.
