Their idea is that the third formant is not affected as much as the first and second formants from the context and therefore more closely related to the ... perceptual warping. For 16 kHz sampled signals, we set α = 0.42 and 0.55 to approximate the Mel and Bark scales, respectively. For 8 kHz, these values are adjusted to α = 0.31 and 0.4...
