• This is a relatively new method for the analysis of speech signals. In this analysis all-pole modeling is applied to an auditory spectrum derived by:
  
  
  • convolving p(w) with critical band masking pattern
    
    
  • resampling the critical band spectrum at approximately l bark intervals
    
    
  • pre-emphasized by a simulated fixed equal loudness curve
    
    
  • compression of the resampled and pre-emphasized spectrum through the cubic root non-linearity, simulating the intensity-loudness power law
