Experience of acoustic analysis of Evenki vocal speech. Part 2

Key Points

The study shows complex acoustic patterns in Evenki vocal speech, particularly in melismatics.
It reveals a falling intonation contour for descending grace notes and a unique orchestration of pharyngealized vowels.
The analysis identifies a three-stage mechanism for executing mordents, impacting vowel intensity significantly.
The findings indicate smooth pitch changes during glissando, contributing to the understanding of vocal phonation in Evenki songs.

Abstract

This article presents the experience of acoustic analysis of a songimprovisation of one of the idiolects related to the UstNyukzha local accent of the Eastern dialect of the Evenki language. The aim was to compare vocal timber effects on vowels and their duration and formant structure in an Evenki folklore song. We consider the functioning of melismas (grace note, mordent, glissando) from the point of view of phonetic mechanisms involved in the process of generating vocal phonation. The results demonstrate the following acoustic patterns of melismatics: 1) falling intonation contour when implementing a descending grace note; 2) complex threestage mechanism for the implementation of the mordent involving a break in the intonation contour with sharply changing intensity of the pharyngealized and epiglottalized vowel; 3) smooth pitch change in the frequency of the fundamental tone when implementing a glissando. 200 https://doi.org/10.22250/241071902024103200
