  2. Air flow pattern for breathy voice more rounded; i.e., more like a sinusoid. Glottal Source Air flow Because of this more sinusoidal flow signal, the spectrum shows a stronger first harmonic than modal. The more ragged spectrum in the higher freqs (less harmonic regularity) is due to turbulence associated with air escaping thru the glottal chink. This is called aspiration. From Klatt, D.H. & Klatt, L.C. (1990) Analysis, synthesis, and perception of voice quality variations among female and male talkers. J. Acoust. Soc. Am., 87, 820-857.

  3. Clear (non-breathy) Phonation Note: Points 1 & 2 are different ways to say the same thing. • Highly periodic time waveform • Extremely well defined harmonics (i.e., nearly all energy is at multiples of f0) • Weak H1 (explanation later)

  4. Moderately Breathy Phonation Less periodic time waveform Well defined harmonics only in the low frequencies Much stronger H1 (explanation later)

  5. Very Breathy Phonation • Even less periodic time waveform • Well defined harmonics only in the low frequencies • Very strong H1 (explanation later)
