Control of the head involves somatosensory, vestibular, and visual feedback. The dynamics of these three feedback systems must be identified in order to gain a greater understanding of the head control system. We have completed one step in the development of a head control model by identifying the dynamics of the visual feedback system. A mathematical model of human head tracking of visual targets in the horizontal plane was fit to experimental data from seven subjects performing a visual head tracking task. The model incorporates components based on the underlying physiology of the head control system. Using optimization methods, we were able to identify neural processing delay, visual control gain, and neck viscosity parameters in each experimental subject.

The Voice

Modern personal computers are fast enough to analyze singing and provide real-time visual feedback of relevant acoustic elements. This feedback provides a quantitative dimension to the learning process in support of developing appropriate sung outputs. However, no computer-based system can replace the singing teacher, as the qualitative listening of an experienced musician cannot be replicated by a computer algorithm. The application of real-time visual displays can facilitate greater efficiency in learning fundamental skills through direct feedback in lessons and during private practice, leaving the teacher more time to work on qualitative aspects of performance that a computer cannot contribute to, such as stagecraft, interpretation, understanding the words, collaborating with an accompanist, and when to use different voice qualities. This chapter describes typical displays that are used in real-time visual feedback systems for singing training and considers how spectrography in particular can be used in pedagogical practice in the voice studio.
