Show 37 Figure 5. Spectrograph of multiphonic ingressive fry. 26. Notice the lower, weaker fundamental in yellow that stays stationary while the main fundamental and its overtones ascend. Overpressure, or windpipe noises, have been heard by most people thanks largely to Louis Armstrong's singing of "What a Wonderful World." Wishart believes that the overpressure technique originates from the shaking of the windpipe below the larynx, and it certainly helps to think of this when learning to produce overpressure. Overpressure may be produced by itself (audio example 27), or combined with the vocal folds (audio example 28). The final lunged nonvocal fold category is forced blown sounds. What overpressure was below the larynx, forced blown sound is above the larynx. Forced blown sound requires constriction above the larynx. Separate pitches are easily produced and perceived in forced blown sounds. Audio example 29 demonstrates a plain forced . blown sound and then forced blown sounds combined with low and high pitches. |
