Frame Blocking and Windowing Algorithm

The signal s(n) of figure1 is blocked into frames of N samples and each adjacent frames are separated by M samples. Thus, the first frame is formed by the first N samples of the speech signal. The second frame is M samples after the first, overlapping it by N-M samples.

What is framing of speech signal?

What is framing ? # Frame blocking or framing is a fundamental signal processing technique that consists of dividing the original signal into blocks often called frames with length an overlap and a framing hop H ( H = N f − M ) .

What is windowing in speech?

Windowing is a classical method in signal processing and it refers to splitting the input signal into temporal segments. The borders of segments are then visible as discontinuities, which are incongruent with the real-world signal.
