Palatal Sound : A Comprehensive Model of Vocal Tract Articulation

Författare

  • Michael Edgerton

Summary, in English

Palatal Sound is a model of vocal tract articulation influenced by physiologic and acoustic analysis of the voice. Specifically, the term articulation refers to all movement within the vocal tract that results in open, filter-like sonorities, as well as in turbulent to absolute airflow modification. This model presents a complete mapping of place within the vocal tract that features flexibility across different vocal tract sizes and proportions. The principles behind this comprehensive mapping of acoustic and physical sound production techniques should not be foreign to those persons who create, combine, design, model or research sound. Therefore, this model might suggest avenues of sound exploration regardless of media or application. This text first presents a brief overview of the current trends of oral modification using vowels, followed by an introduction to and acoustic analyses of the comprehensive vocal tract model as applied to open-like sonorities. This model is then expanded through the presentation of other methods of open-like behaviours. Following the discussion of open sonorities, turbulent-like behaviours are discussed by first identifying the use of language-based fricatives and stops. After this (re-)exposition, the comprehensive model is applied to turbulent structures through examples and acoustic analyses. Finally, these turbulent methods are completed by additional, complementary methods of vocal tract turbulence. The intentions of this paper are: (i) to document this model clearly, (ii) to identify differences between speech and song articulatory behaviour and that of this comprehensive model with the aid of selected acoustic analyses, (iii) to suggest that this model renders valuable scientific information about the limits of vocal tract physiology, and (iv) to propose the practical use of this model by composers and performers.
