Paper seminar by Young Joon Moon.  Presented on: 2017-11-16
a. Title: RASTA-PLP Speech Analysis
   Authors: Hynek Hermansky et al. 
b.Title: Revising Perceptual Linear Prediction(PLP)
  Authors: Florian Honig et al.
Using those two papers, the concept of PLP and MFCC (Mel Frequency Cepstral Coefficients) was introduced and also the computation steps of PLP and MFCC were introduced. Based on those information, possible enhancement of performance of the filter banks, which are used those speech analysis methods, was discussed.
PLP has good performance in the present of noise when it is compared to MFCC. However, in a clean acoustic environment, both feature types have about equal results especially on HUB4 which is acoustically less homogeneous.
