Acoustic Analysis 
Acoustic Analysis is an analysis of the voice range and voice quality made at the time of the initial evaluation. Acoustical analysis provides an objective measure of severity of the voice disorder.

Aerodynamic Evaluation
Aerodynamic Evaluation is an assessment of vocal function or voice use which determines the air pressures and air flow rates used during various voice tasks. Excessive air pressure or air flow usually results in improper use of the voice. Information from the aerodynamic assessment is used in planning treatment of the voice disorder.

Trial Voice Therapy
Trial Voice Therapy is the use of specific exercises during the voice evaluation to determine if and what type of changes the patient is capable of making with his/her voice

Video Strobolaryngoscopy
Video Stroboscopy is a specialized diagnostic procedure in which a stroboscopic light is used in conjunction with a laryngoscope to electronically slow down the motion of the vocal folds in order to identify subtle changes in vibratory patterns that are diagnostically significant. Video Stroboscopy is used to differentiate vocal fold nodules from vocal fold polyps and cysts. With the use of a camera and video recording system, the examination can be viewed many times by the examiners and patient.

Voice Handicap Inventory
A Voice Handicap Inventory is a valid and reliable self-assessment tool for use by patients to determine their perception of the severity of their voice. Other self-assessment instruments such as the Voice Related Quality of Life (VRQOL) also are used for this purpose.

Voice Range Profile
A Voice Range Profile is a test of vocal function to determine the frequency and intensity (pitch and loudness) limits of one's voice.
