Abstract
A method of and a device for deriving formant frequencies from a part of a speech signal. For determining the formant frequencies from a part of a speech signal located within a given time interval, the Split Levinson algorithm is used. In the Split Levinson algorithm a higher order singular predictor polynomial (P.sub.k (z)) is each time determined in successive recursion steps. After the last recursion step the formant frequencies (f.sub.1, f.sub.2, . . . ) are determined.
