Tinnitus evoked by speech.
Modulation of tinnitus by a variety of somatosensory stimuli and alteration of gaze has been described. We present two cases of tinnitus induced by speech (voice). The tinnitus was troublesome in both patients, and both had hearing loss and ischemic changes in the central nervous system documented by magnetic resonance imaging. We discuss cross-modal plasticity and how it may explain the tinnitus in these two patients.
