Global Online Education for Speech Science Competency (GOESSC) was established in 2004 to provide guidelines and multimedia teaching software for effective teaching of basic speech science (undergraduate level) and applied speech science (graduate level) courses.

The ultimate goal of teaching speech science courses to speech pathology students is to facilitate their effective learning of very complex Multifunctional Relationships among Anatomy, Physiology, Acoustics, Perception, Pathology, and Measurement of Speech.

Six GOESSC teaching software programs were developed by Byoung W. Kim, Ph.D. and John Grozik, M.S. during their tenure at University of Wisconsin-Milwaukee to simplify the Complexity of the Multifunctional Relationships via Multimedia Simulation (Theory-based Animation).

The List of Six GOESSC Interactive Multimedia Teaching Software:

  1. Phonetic & Perception Simulations
  2. Simulation of Respiration, Phonation, & Prosody
  3. Neuroscience for Human Communication: Neural Information Flow from Intention to Articulation  
  4. Speech Articulation: Animation of Muscle Vectors
  5. Applied Speech Science for Dysarthrias
  6. Applied Speech Science for Voice & Resonance Disorders

The PowerPoint Show files for all GOESSC Interactive Teaching Software have been recently created and made available for free download for the purpose of introducing the major content of the software. All files are PPT Slide Show of Key Images without Audio except for “Phonetic & Perception Simulation” which has full audio wav. files of major English Speech Sounds. For the use of full application software, you will need to purchase the GOESSC interactive multimedia software. They are fully compatible with Windows XP, Vista, 7 (32-bit), and 7 (64-bit) Professional  Operating System with XP-Mode/Virtual PC (free download).

Please contact Byoung W. Kim, Ph.D. ( for more information.
