Subject: Speech Processing

Topic: Speech Analysis in Time Domain

Difficulty: Low

(i) The short-time processing technique (in both time and frequency) produce parameter signals of the form

$ U(n) = \sum_{m=-\infty}^{\infty} T[S(m)] W(n-m) $ .....(1)

where, S(n): Speech signals

U(n): Non-zero value

W(n): Window function

U(n) corresponds to short-time energy or amplitude if T in eq.(1) is squaring or absolute magnitude …
