BIOS1163: Speech Science

This unit aims to provide an understanding of the anatomy, physiology and physics of speech. Students will gain a detailed knowledge of the anatomy of the head and neck as well as functional activities involving swallowing and speech. In addition student will learn the role of physics in sound production. Control of breathing and respiration in normal and pathological condition is also covered in this unit. Practical classes will take a case-based approach to learning. This unit includes laboratory classes in which human cadavers are studied; attendance at such classes is required.

At the completion of this unit, you should be able to:

  • LO1. Use anatomical and directional terminology appropriately.
  • LO2. Understand the ethics of working with human cadavers.
  • LO3. Name and describe the structure and function of the four basic tissues in the body, and the basic structure of the peripheral nervous system.
  • LO4. Identify and describe the anatomical features of the skull and describe the differences between adult and foetal skulls.
  • LO5. Understand and describe the anatomy and movements of joints, focusing on the temporomandibular joint, and identify and describe the anatomy, movements and innervation of the muscles of mastication and facial expression.
  • LO6. Understand and describe the anatomy, function and innervation of the oral cavity, the hard and soft palates, pharynx, larynx and their component structures, and their influence on swallowing, sound production and speech.
  • LO7. Understand and describe the blood supply and lymphatic drainage of the head and neck, and understand the role of the lymphatic system in disease.
  • LO8. Understand and identify the sensory and motor nerve supply to the head and neck, and be able to deduce the effect of a nerve lesion on speech and swallowing.
  • LO9. Understand, define and apply principles of physics associated with production of speech including vibrations and waves, superposition of waves, standing waves, frequency response curves and Fourier’s theorem, sound production, fluid flow and the Bernoulli principle, myoelastic aerodynamic theory and source filter theory.
  • LO10. Understand and describe the normal anatomy and physiology of the respiratory system.
  • LO11. Understand the basic processes of respiration and the roles of relaxation pressure, maximum inspiratory pressure and maximum expiratory pressure in respiration for speech.
