C_S_D 3220 Lecture Notes - Lecture 5: Eth, Vocal Folds, Formant
Document Summary
Foundation for many procedures of acoustical analysis of speech. We"re skimming the surface of this one . Considering your entire vocal tract as filter. Voice energy from larynx is modified by vocal tract constrictions and openings. Moving beyond just bumps and ridges to the real points of constriction and the. Let"s think about the points of resonance of the vocal tract ( pipe ) Mathematical formula that predicts where sound will resonate along a pipe. Formula based on speed of sound and length. Let"s consider resonance and length of the pipe. Resonances (based on odd-quarter wavelength formula) will be at 500, What if we made it half as long? (infant) Length of the vocal tract will determine your resonance frequencies. Your text is reporting data from (mostly) adult males. Age and sex mostly determine vocal tract length. Resonance frequencies are not really affected by straight or curved pipes. I like to move it: http www. youtube. com/watch? v=ffglpio620y&feature=related.
