High-speed imaging of the vocal folds is a cutting-edge tool that captures the vibration of the vocal cords in extreme detail—up to thousands of frames per second. It's especially useful when standard video stroboscopy doesn't provide enough information, such as in cases with irregular or asymmetrical vibration, vocal tremor, or subtle scarring that may not be seen with slower imaging methods. This test is ideal for singers, performers, or anyone with complex or persistent voice problems.

The procedure is done in the office and usually takes about 10–20 minutes. A small endoscope is placed through the mouth or nose while you perform specific vocal tasks. It is not painful, but you might feel a bit of pressure or discomfort, especially if done through the nose — numbing spray helps reduce this. The actual imaging part is quick and safe, with no sedation needed and no recovery time. You can speak normally afterward. The high-resolution video gives your doctor valuable insight into the precise mechanics of your voice and helps shape a personalized treatment plan. This test carries minimal risk and often complements other voice evaluations like stroboscopy or acoustic analysis.
