Short Time Energy
Equals the [see page 5, sum] of the squares of the samples in one frames.
\[ E = \sum{L_{Bl}-1}{s2 [iT]} \] Where:
| \( E \) | Short-time energy. |
|---|---|
| \( L_m \) | Length of block \( m \). |
| \( s[iT] \) | Sample no \(i\) of signal \(s\). |
Note: This value is large for voiced speech segments.
