METHOD OF AND 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 (Pk(z)) is each time determined in successive recursion steps (54, 55, 56, 5...

Zusammenfassung: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 (Pk(z)) is each time determined in successive recursion steps (54, 55, 56, 57, 58, 59, 60). After the last recursion step the formant frequencies (f1, f2, ...) are determined.
