This paper compares the performance of a filter bank with merely 8 channels to other preprocessing methods in a speech recognition task. The filter bank is the product of former investigations in perception of German long vowels which are shortly summarized. Although the application of the 8 channel filter bank reduces the computing expense drastically, the recognition results are comparable to those of other algorithms. Consequently, the filter bank may be recommended for low cost preprocessing.
