Abstract
A speech analyzing stage () and a method for analyzing a speech signal is described. The speech analyzing stage () is part of an automatic speech recognition system () and is adapted for analyzing in the spectral domain a speech signal sampled at one of at least two different system sampling rates. The speech analyzing stage () comprises a first spectral analyzer () for analyzing the speech signal up to a first frequency (f) which is preferably derived from the lowest system sampling rate (2×f) and a second spectral analyzer () for analyzing the speech signal at least above the first frequency (f).
