Voice tremor is one of the most common and arguably most socially debilitating forms of tremor as it significantly impairs daily communication and social interactions of an affected individual. It is, however, clinically under-evaluated, partially due to unclear voice tremor classification and challenges with its differential diagnosis. While the understanding of the voice tremor is still being developed, in this chapter we define it as a symptom present in a spectrum of neurological disorders. We focus on essential tremor and laryngeal dystonia where voice tremor represents one of the common symptoms and briefly discuss voice tremor presentations in other neurological disorders. Our goal is to summarize the most recent interdisciplinary developments in voice tremor classification, pathophysiology, and treatment, as well as outline the prospective diagnostic and therapeutic horizons for those who suffer from.
