1.Psychoacoustic Evaluation
- Psychoacoustic evaluation is a method that analyzes the subjective characteristics of patients’ voice in objective features.
2.Phonatory Aerodynamic Test
- Voice is created as the air pressure from the lung makes the vibration in the air through the larynx and passes through the pharynx to form a sound. The inhaled air is the source of energy for the voice. Thus aerodynamic evaluation is essential in identifying the mechanism of vocal disorders.
3.Speech and Voice Acoustic study
- Acoustic evaluation checks the overall voice quality by measuring voice indexes which represent the characteristics of vocal fold movement.
4.Voice Range Profile Program
- Voice range profile program shows the phonation amplitude and phonetic pattern of voice pitch range through 5 note-scale phonation
5.Rhino-Laryngeal Stroboscope
- Rhino-laryngeal storoboscope shows the vocal folds in a clear image and is a very useful method of observing the characteristics of vocal fold vibration and identifiying disorders during phonation.
