Conceição Cunha, Samuel Silva, António Teixeira, Catarina Oliveira, Paula Martins, Arun A. Joseph, Jens Frahm
2019 Interspeech 2019  
For this study, while the analysis of data for more speakers is ongoing, we considered a set of two EP native speakers and addressed the study of oral and nasal vowels mainly in the context of stop consonants  ...  The characterisation of nasal vowels is not only a question of studying velar aperture.  ...  We thank Philip Hoole for the scripts for noise supression and all the participants of the experiment for their time and voice.  ...

Compensatory articulation in American English nasalized vowels

Christopher Carignan, Ryan Shosted, Chilin Shih, Panying Rong
2011 Journal of Phonetics  
In acoustic studies of vowel nasalization, it is sometimes assumed that the primary articulatory difference between an oral vowel and a nasal vowel is the coupling of the nasal cavity to the rest of the  ...  Acoustic modulations observed in nasal vowels are customarily attributed to the presence of additional poles affiliated with the naso-pharyngeal tract and zeros affiliated with the nasal cavity.  ...  This research has been presented on a number of occasions and we are grateful to the many audience members who have presented us with suggestions and challenges along the way.  ...
