- W2023228304 abstract "This paper considers the estimation for formant frequencies and bandwidths from voiced speech signals that are degraded with additive white noise. Each period of the speech signal is divided into the open and closed glottal phases using the electroglottograph signal. The speech signal in the closed phase is modeled as the sum of damped sinusoids, with each sinusoid corresponding to one formant. The analysis procedure thus leads to an estimate of the frequency, bandwidth, and energy of each formant. The results indicate that typically just three formants account for most of the energy in the closed phase. The noise-robustness properties of the algorithm are increased by using a total least-squares approach in obtaining the parameters and by using data from multiple consecutive closed phases. This work verifies and extends the results of S. Parthasarathy and D. Tufts [IEEE Trans. Acoust. Speech Signal Process. ASSP-35, 1241–1249 (1987)].
