Term
| If F1 is tuned near to H1 |
|
Definition
Inertance becomes insynch with the vibration
• Threshold of phonation pressure lowers
• Phonation occurs with less effort |

| Basics of Vocal tract innertance |
|
Definition
a tube w/a column of air in it
-vocal tract shape can course inertance to be in or out of sync w/vocal folds, thereby affecting phonation in sync=aids out sync = ceases |

| All Formant frequencies lower uniformly when |
|
Definition
| the vocal tract is lengthened or w/lip rounding |
|
|
Term
| All Formant frequencies rise uniformly when |
|
Definition
| the vocal tract is shortened or w/lip rounding |
|
|
Term
|
Definition
| "The sound source is the time-varying glottal airflow & the filter is the vocal tract. Whereas the glottis produces a sound of many frequencies, the vocal tract selects (filters) a subset of these frequencies for radiation from the mouth |
|
|
Term
|
Definition
- a resonance of the vocal tract
- a spectral maximum frequency
- a peak in a filter model (LPC or LTA) |
