Glottalization of vowels in the dialect of Lamunkhin Evens

The article presents an acoustic analysis of glottalized vowels and glottal consonants of the Lamunkhin dialect of the western dialect of the Even language. The problem of the experimental study of vocalism and consonantism of Even dialects remains unresolved to date, since their description has long been carried out through auditory perception and subjective assessment. There is  a threat that in the near future the sound features of the Lamunkhin dialect of the Even language may disappear without proper  research  attention.  The  purpose  of  the  work  is  to  study  a  one-time  glottal insertion  (explosion,  bow,  click),  glottalization,  as  well  as  the  glottal  gap  (attack, indentation) using accurate objective methods. The novelty of this work is due to the fact that for the first time on the material of the Even language, a special study of various types of additional laryngeal articulation, formed when the glottis is narrowed and closed, was undertaken. An auditive analysis of the sound of vowels and a visual interpretation  of  their  illustrations  –  spectrograms  and  oscillograms  were  made. The  analysis  made  it  possible  to  formulate  the  following  conclusions:  for  glottal bowed and gap consonants, the obligatory is the preposition to initial vowels and the postposition to final vowels; the glottal insertion can act as a borderline suture between two vocal nuclei in the vowels of a complex formation; in spontaneous speech, the glottal  bow  appears  sporadically  in  place  of  anterolingual  consonants  such  as  [t] and [d]. In articulatory terms, all these phenomena are modeled by true vocal folds. The results of the study can be used in expanding the theoretical laws and principles of the phonetics of the Even language, in creating educational and methodological manuals for teachers and philologists of higher educational institutions
