A voice specialist will discuss your voice problems, vocal needs, activities, and medical and voice use history.  Additional tests may be recommended:

• Laryngeal Videostroboscopy
  Videostroboscopy provides a view of your vocal folds and larynx. A special light and camera capture and digitally record rapid vocal fold movement during voicing, speaking or singing. 

• Aerodynamic and Acoustic Analysis
  As you speak into a microphone, instruments translate such factors as hoarseness, pitch and loudness into a visual and numerical screen display. This allows a voice specialist to determine how well your systems of voice production are functioning.

• Nasometry
  Impaired voice quality may be a result of problems with the soft palate, which may in turn cause speech to sound hypernasal.  This sometimes occurs in adults with neurological conditions, but is most often seen in children who have been born with a cleft palate or velopharyngeal incompetence (VPI).
