| These devices modify supraglottal impedance, potentially decreasing the aerodynamic power necessary for phonation. |
| Supraglottal injection of botulinum toxin type A in adductor type spasmodic dysphonia with both intrinsic and extrinsic hyperfunction. |
| Vocal effort in loud voice is produced with increased subglottal pressure during vowels and increased supraglottal pressure during consonants. |
| The airflow was visualized in the immediate supraglottal region using a laser-sheet technique and a digital high-speed camera. |
| The cross-section of the supraglottal channel was systematically varied by increasing the distance between the lateral channel walls. |
| The results clearly showed different flow characteristics depending on the supraglottal configuration. |
