Testing Offered at the Voice Center

At NYU Langone’s Voice Center, we provide the specialized testing required to accurately diagnose the cause of your voice, swallowing, or breathing-related condition.

Testing for Voice Disorders

At the Voice Center, we provide an individualized treatment plan based on the results of our advanced diagnostic testing for voice problems.


Stroboscopy is a way to examine the vibratory nature of the vocal cords. The technique uses a strobe light that is linked to the frequency of the patient’s voice. When a person utters a tone, the light flashes at a frequency that is close to that of the person’s voice.

The result is a set of images that mimic the vibration of the vocal cords. Doctors use this information to diagnose and evaluate the vocal cords for the presence of cancer, scar tissue, or stiffness, as well as muscle tone.

Voice Analysis

Hoarseness is often a complicated condition to evaluate because vocal changes can be very subtle. We use a series of tests to analyze your voice and help determine the cause. Typically, the evaluation involves a voice recording, which is then run through a series of computer programs that analyze the data. This analysis provides information on your vocal quality and ability and helps us determine the best way to help you get better.

Testing for Swallowing Disorders

Our team may use one of several methods to examine and evaluate your swallowing problem during a visit to the Voice Center. Learn more.
