LECTURE 03: SOUND PROPAGATION

• Objectives:
  
  
  • Basic properties of lossless tubes
    
    
  • Resonant structure of the vocal tract
    
    
  • Articulator positions (basic speech sounds) translate to predictable spectral signatures
    
    
  • Digital filter-based models of the vocal tract (linear acoustics)
    
    
  • Relationship of the parameters of these digital models to speech recognition.
