Fundamental to appropriate diagnoses and treatment of vocal fold pathology is direct visualization of laryngeal structures and vocal fold vibratory patterns. Clinical evaluation of laryngeal pathology, and its impact on vocal fold vibration, has been aided in the last three decades by technological developments that have permitted clinicians to visualize the larynx during voicing and to make relatively inexpensive permanent recordings of the visual image synched with the acoustic signal. The current gold standard of clinical observation of laryngeal vibration is stroboscopy (Hartnick & Zeitels, 2005). Studies have reported that stroboscopy improves diagnoses of vocal pathologies when compared to straight endoscopic light thereby improving treatment decisions in 1433% of patients typically seen in oto-laryngology practices (Casiano, Zaveri, & Lundy, 1992; Sataloff, Spiegel, & Hawkshaw, 1991; Woo, Colton, Casper, & Brewer, 1991).
