“…It allows the decomposition of discrete time signals into sinusoidal components whose frequencies are multiples of a fundamental frequency [4][5]. The amplitudes and phases of the sinusoidal components can be estimated using the FFT and is represented mathematically as For a given bio-signal ( ) x n whose sampling period is T with N number of total samples (NT is therefore the total duration of the signal segment).…”

“…And it is an FFT algorithm that computes the discrete Fourier transform (DFT) of arbitrary sizes (including prime sizes) by re-expressing the DFT as a convolution. Bluestein's algorithm can also be used to compute a more general transform based on the (unilateral) Z-Transform [4][5][6]. In particular, it can compute any transform in the form: …”

“…For many applications of emotion recognition, such as virtual agents, the system must select responses while the user is speaking. However, some emotion recognition systems are based on turn-wise processing [8][9][10].…”
