Instrumentation “The altar of technology” (Chial, 1990)
Options for Quantitative Evaluation(s) • Acoustic analysis • Respiratory Analysis • Resonance Analysis
Respiratory Analysis • Aerophone (Kay Elemetrics) • Pulmonary Function Analyzer (Kelleher Medical) • Computer supported-digital • Analog devices
Acoustic Analysis • Kay Elemetrics • Computerized Speech Laboratory (CSL) • Visi-Pitch II • Laryngograph • Tiger Instruments • Dr. Speech (Minifie) • C-Speech (Malinovic)
Resonance • Nasometer • Spectroscopy
Respiration • Vital capacity for speech needs • variety of pressure, force and ratio • calibration • cleaning/disinfecting
Acoustics • Frequency, Intensity and Waveform • Fundamental Frequency: F0 • modal • Perturbation measures • jitter: relative average perturbation (Koike) • “hoarseness” • shimmer:
Resonance • Nasalance: oral-nasal acoustic ratio • Kay Elemetrics, Pine Brook, New Jersey • “Nasogram” • Quantification of nasality
