Brief Summary
This is a study of patients with spasmodic dysphonia to determine how best to measure the severity of the disorder in patients. It addresses which characteristics of speech are the best indicator of whether or not a particular treatment has benefited a person with spasmodic dysphonia. We hope to recruit 20 participants each at 2 different centers. The evaluation for each participant will be done on a two visits, one just before and another several weeks after treatment.
