The purpose of this study is to describe, from literature review, acoustic analysis using Multi Dimensional Voice Program, reliability of their measurements and their comparison with other acoustic analysis programs; characterization of voices of different groups, and its use to assess the effects and effectiveness of different therapeutic procedures. Conducted literature that prioritized the past five years, including articles whose purpose was according to the interest of this review. The survey was conducted in the databases of Lilacs, BIREME, PubMed, Medline, SciELO and Google Scholar, using the descriptors acoustic, speech acoustics and voice. The most commonly used measures are fundamental frequency, jitter, shimmer and harmonic-noise ratio. The measures of tremor not have as much reliability. The most consistent measures that present a high correlation with other acoustic analysis programs are related to fundamental frequency. Several studies aim to characterize different types of voices such as those of subjects without vocal of both sexes, in order to establish normality parameter for different population groups. In addition, some studies were characterized with different voices disorders. Acoustic analysis is a resource objective and necessary in the evaluation of patients with voice disorders and especially the comparison of several uncles treatment. KEYWORDS: Voice; Speech Acoustics; Voice Quality; Speech Recognition Software; Acoustics Este estudo tem como objetivo descrever, a partir de revisao de literatura, a confiabilidade da analise acustica utilizando o Multi Dimensional Voice Program, comparacao de suas medidas com outros programas de analise acustica; caracterizacao de vozes de diferentes grupos; e sua utilizacao para verificar os efeitos e eficacia de diferentes procedimentos terapeuticos. Realizou-se levantamento bibliografico que priorizaram estudos dos ultimos cinco anos, incluindo-se artigos cujo objetivo estivesse de acordo com o interesse da presente revisao. A pesquisa foi realizada nos bancos de dados das bases Lilacs, BIREME, PubMed, MedLine, Scielo e Google Schoolar, por meio dos descritores acoustic, speech acoustics e voice. As medidas mais utilizadas sao frequencia fundamental, jitter, shimmer e proporcao harmonico-ruido. As medidas de tremor nao apresentam boa confiabilidade. As medidas mais consistentes que apresentam alta concordancia com outros programas de analise acustica sao as relacionadas com a frequencia fundame
