My recent work as an artist is centred around a search for what Heidegger calls an “experience with language”—moments in which our awareness of language spikes and our relationship with it changes. Where I found the most potential is on the sound/sense continuum of the human voice, and it is an oscillation between the extremes of this continuum that defines my recent works. This paper examines these works and their underpinning ideas, but focuses on the culminating project of my thesis: Solo for Self-Talk Chamber. For this project, I spoke aloud to myself for fourteen hours, one hour at a time, in a purpose-built room. The process was documented and exhibited as a book work, a video and a performance, all of which are discussed in detail.

During phonation, the vocal folds collision during the glottal closure is considered to be a risk factor for pathological development. This thesis is aimed at designing a dependable finite element analysis (FEA) model of the vocal folds for frequency and dynamic analysis and for calculating the impact stress between the vocal folds during glottal closure. A three-dimensional model with irregular geometry and a layered structure was designed. The measured viscoelastic properties of the vocal-fold mucosa and the transverse isotropic elastic properties of the vocal fold muscle are applied to the model. The boundary conditions are assumed to be fixed on lateral, anterior and posterior surfaces based on anatomical structure analysis. This model is symmetrical about the right and left vocal folds.The frequency and dynamic characters are presented using the software ABAQUS. The FEA model is validated by both experimental modal analysis (EMA) model results and in-vivo experimental results from the literature.In the vibration analysis, the eigenfrequency and eigenmode of the FEA model are determined. The model results compare well with the experiments performed on a silicone vocal fold model. The eigenmodes show the vibration direction at different excitation frequencies. In the closure process, the closure and collision dynamic results are obtained. The results show that: (1) the closure process is independent of the subglottal pressure; (2) the glottal opening amplitude and closing velocity vary approximately linear with the subglottal pressure; (3) the maximum impact stress occurs on the mid area of the inferior surfaces; (4) the impact stress is approximately linear with the subglottal pressure; and (5) the impact stress will cause vocal fold tissue damage when the subglottal pressure is over 800 Pa.It is anticipated that the model will help to identify voice disorders such as vocal-fold paralysis and vocal-fold nodules.

This project explores the unseen (that which is not considered) in relation to the idea of the existence of another dimension of language. It considers the possibility that, in regard to language, some essential component may have been omitted or unperceived. Through works of art this project explores possibilities for the visual signification of this information. My interest is in exploring ways in which these qualities can be recovered by creating representational codes of the unseen, which evoke a potential for an inclusive language. My enquiry focuses on sound with particular emphasis on 'voice' as a way in which to explore these concepts through visual means. Voice is considered as something which projects or articulates or otherwise could be described as 'speaking'. For example voice is considered in relation to thought, and also the human experience of sound in space. This includes sound generated by self, intrinsic and extrinsic to the body. Voice plays two roles - one as a space from which to retrieve the unseen, and the other as a drawing tool - a way in which to represent what seems unrepresentable.
