Abstract :
A new relationship between Filter/Detectors and the Short-Time Fourier Transform magnitude is derived. The result provides a common basis for comparison of speech spectrograms, the sliding Discrete Fourier Transform, average power spectrum estimation techniques, perception-based speech analysis systems, and channel vocoders.
