L-D Algorithm:

(i) Take 128 samples of speech signals.

(ii) Find the value for auto-correlation coefficients for segment length equal to 128 - |l - k|, where (l-k) denotes the offset. We use the formula to find the normalized auto-correlation given by: $$ \gamma_{xx}(i) = \frac{\sum_{i=1}^{N-i} x(k)x(k+i)}{\sqrt{\sum_{i=1}^{N-i} x(k) x(k) + …
