A Robust Formant Extraction Algorithm Combining Spectral Peak Picking and Root Polishing

Blog Article

We propose a robust formant extraction algorithm that combines the spectral peak picking, formants location examining for peak merger checking, ventilationstejp and the root extraction methods.The spectral peak picking method is employed to locate the formant candidates, and the root extraction is used for solving the peak merger problem.The location and the distance between the extracted formants are also utilized indecent perfume to efficiently find out suspected peak mergers.The proposed algorithm does not require much computation, and is shown to be superior to previous formant extraction algorithms through extensive tests using TIMIT speech database.
