Recently, the Lax Vox voice therapy has been used as one of the SOVTE(Semi-Occluded Vocal Tracts Exercise). The purpose of this study was to explore the effect of Lax Vox voice therapy for a patient with Spasmodic dysphonia on voice improvement. One female spasmodic dysphonia patient(age=27) who had been diagnosed by a laryngologist received Lax Vox voice therapy. The Lax Vox protocol was configured as 5 steps (1 warm-up and 4 steps : bubbling without / with phonation/ gliding with phonation/ generalization) in this study. A total of 11 sessions were performed by a certified speech language pathologist. The present study evaluated the acoustic, aerodynamic, auditory perceptual, and patient's self-rating between pre-, mid-, and post- voice therapy. All objective and subjective parameters were improved after voice therapy; Reduced frequency variation, increased maximum phonation time, enlarged voice range, improved 'G' and 'S' in GRBAS & USDRS, and reduced VHI were observed. Especially, decreased
