![]() Ghazeli, S.: Back Consonants and Backing Coarticulation in Arabic. The methods that you use for estimating the LPC model may also influence the result. Since speech signals are evaluated up to the 4th formant, a 8th order LPC/AR model should be sufficient for most applications. Each spectral peak requires a pair of complex conjugates AR poles. FFT finds the energy distribution in the actual speech sound, whereas LPC estimates the vocal tract filter that shaped that speech. 870–882 (2000)ĭeng, L.: A Database of Vocal Tract Resonance Trajectories for Research in Speech Processing. To do formant analysis you dont need such big filter order. There are two methods for spectral analysis: the fast Fourier transform (FFT) and linear prediction (LPC). 1017–1020 (2006)īoudraa, M., Boudraa, B., Guerin, B.: Twenty Lists of Ten Arabic Sentences for Assessment.
