Webcommonly of the order of 0.3 to 0.7. The glottal volume current therefore has a frequency spectrum relatively rich in overtones or harmonics. Because of the approximately triangular waveform, the higher frequency components diminish in amplitude at about 12 [dB/octave]. The waveform of the glottal volumeﬂow for a given individual can vary widely. WebSource=vocal folds. Timing of the opening/closing of the vocal folds is plotted on a glottogram. 2. Filter=vocal tract. How the vocal tract filters the glottal source signal changes the frequency. 3. Speech signal=blending of the glottal source and vocal tract. Measures the acoustics outside of the mouth. 1 + 2 = 3 // 3 + -2 = 1.
