  1. Instrumentation “The altar of technology” (Chial, 1990)

  2. Options for Quantitative Evaluation(s) • Acoustic analysis • Respiratory Analysis • Resonance Analysis

  3. Respiratory Analysis • Aerophone (Kay Elemetrics) • Pulmonary Function Analyzer (Kelleher Medical) • Computer supported-digital • Analog devices

  4. Acoustic Analysis • Kay Elemetrics • Computerized Speech Laboratory (CSL) • Visi-Pitch II • Laryngograph • Tiger Instruments • Dr. Speech (Minifie) • C-Speech (Malinovic)

  5. Resonance • Nasometer • Spectroscopy

  6. Respiration • Vital capacity for speech needs • variety of pressure, force and ratio • calibration • cleaning/disinfecting

  7. Acoustics • Frequency, Intensity and Waveform • Fundamental Frequency: F0 • modal • Perturbation measures • jitter: relative average perturbation (Koike) • “hoarseness” • shimmer:

  8. Resonance • Nasalance: oral-nasal acoustic ratio • Kay Elemetrics, Pine Brook, New Jersey • “Nasogram” • Quantification of nasality
