This study has been performed to determine the details of voice disorders in hypothyroidism. Materials and methods: Hypothyroidism was confirmed in fifteen patients examined by an endocrinologist, using hormone laboratory tests. In all patients T4 level was less than 5 mg[d] and TSH level was over 10 mu/L. the vocalization and speech quality of all the cases were recorded and analyzed using the MDVP program by Visipitch system. Results: The result of this study indicates that the majority of cases suffer from some degrees of dysphonia dryness of pharynx & larynx, hoarseness & the feeling of having a lump in their larynx are among the common complaints of these patients. Fundamental frequency (FO) in their voices with mean & SD (200  47 Hz) indicates a meaningful difference with normal values (P<0/01). Jitter parameter in studied patients with mean & SD (1/79  1/31) also indicates a meaningful difference with normal values (p<0/01). This is also the case with the Shimmer parameter in the studied patients with mean & SD (6/15  4.66) implying a meaningful difference with normal values (p<0/01). Conclusion: This study indicates that voice problems are very common in hypothyroidism.
