The purpose of this study is to conduct a literature review focused on the instruments used to assess an objective and qualitative voice of teachers. A bibliographic review of the publications listed in PubMed and Scielo over the past 5 years, was performed which were connected with the evaluation of voice teachers. The instruments used in the 15 articles found show that 80% of the studies involved questionnaires, 40% performed auditory perceptual assessments of the voice, 40% used telelaringoscopía or videostroboscopy, 33% did speech therapist or speech therapy evaluation, 27% performed sound analysis of the voice, laryngeal evaluation accounted for 27%, 27% use protocol characterization of the sample, 13% used a VHI scale, 13% evaluated the aerodynamic parameters, and only 7% used auto-co-hetero, a GRABSI scale, evaluation of articulation and posture, orofacial motricity assessment and dental evaluation. Several assessment tools were found that account for the diversity of both the instruments and the procedures used to evaluate the voice used especially in regard to questionnaires, and subjective evaluation protocols. Medical devices have a standard application protocol that allows you to replicate the procedure in the same way in different parts of the world; but in Speech Therapy all the procedures depend on the availability of instruments and the professional experience of the therapists.
