Term | Definition |
---|---|
Respiration perceptual meas. | Max phonation time, shallow clavicular, thoracic, diaphragmatic/abdominal breathing, poor efficiency |
Respiration instrumental meas | Water manometer (sub glottal pressure 5for5). Spirometer: airflow (increased w/ lesions & weakness), lung volumes |
Phonation (quality) perceptual meas | Rating scales (GRBAS). S/z ratio. Attack/onset (hard, breathy, fry, simult). Rate (fast/slow), vocal register, |
Phonation (quality) instrumental meas (physio) | Biopsy. Laryngoscopy. Videoendoscopy. Stroboscopy. Electroglottograph. (glottal pulse, shape, open/close phase, irregular TVC motion/closing, mucosal wave, decreases with sustained phonation) |
Phonation (quality) instrumental meas (acoustic) | Visipitch -jitter/shimmer, noise, harmonics, turbulence. Spectogram |
Pitch perceptual meas. | Pitch range (2-3 oct). Best optimal pitch. Pitch matching. |
Pitch instrumental meas. | Visipitch - freq analysis, max freq range, habitual fundmtl freq, jitter |
Loudness perceptual meas | Inside/outside voice, Loud to soft. Soft to loud |
Loudness instrumental meas | Visipitch -shimmer, max/min intensity, dB analysis |
Resonance perceptual meas | Nasal/non-nasal sentences. Nares occluded. Foggy mirror test. |
Resonance instrumental meas | Transnasal endoscopy. Nasal manometer. Pressure bulb. Nasometer. |
Qualities of resonance | Hypernasality (on vowels & v+ consonants). Hyponasality (on nasal consonants). Nassal emission (on v- consonants). Assimilative nasality (between nasal consonants). Cul-de-sac (hollow, muffled, mashed potatoes) |
