We propose a robust formant extraction algorithm that combines the spectral peak picking, formants location examining skin of the flayed one for peak merger checking, 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 to efficiently find out suspected peak mergers.The proposed algorithm does not require much computation, and is shown to be superior gyroor c3 electric bike parts to previous formant extraction algorithms through extensive tests using TIMIT speech database.
