Cognitive componets of speech at different time scales

Publication Date
  • Cognitive Component Analysis (Coca) Is Defined As Unsupervised Grouping Of Data Leading To A Group S
  • We Focus Here On Speech At Different Time Scales Looking For Possible Hidden ‘Cognitive Structure’
  • Statistical Regularities Have Earlier Been Revealed At Multiple Time Scales Corresponding To: Phonem
  • Gender
  • Height And Speaker Identity
  • We Here Show That The Same Simple Unsupervised Learning Algorithm Can Detect These Cues
  • Our Basic Features Are 25-Dimensional Short Time Mel-Frequency Weighted Cepstral Coefficients
  • Assumed To Model The Basic Representation Of The Human Auditory System
  • The Basic Features Are Aggregated In Time To Obtain Features At Longer Time Scales
  • Simple Energy Based Filtering Is Used To Achieve A Sparse Representation
  • Our Hypothesis Is Now Basically Ecological: We Hypothesize That Features That Are Essentially Indepe
  • The Representations Are Indeed Shown To Be Very Similar Between Supervised Learning (Invoking Cognit
  • Hence Lending Additional Support To Our Cognitive Component Hypothesis
