摘要：Objectives: To analyze the speech fluency parameters of dishonest speak. Method: Quantitative and cross sectional study with descriptive and analytical approaches. Twenty subjects participated in the research equally distributed between gender and level of education. The narrative of two speeches was filmed, one true (pre-test) and the other false (test), from the simulation of an interview in which the camera is used in video mode. Data were tabulated in an Excel spreadsheet, compared and analyzed by statistical analysis using the chi-square test, the normal distribution test and the t test, presenting significance level of p < 0,05. Results: The mean age of participants was 28.7 ± 9.8. The pre-test (truth) and test (lying) moments did not reveal statistically significant differences when fluency was analyzed or when the number of syllables and words was compared. There is negative correlation in both syllables and words quantities that indicates when a person is speaking the truth it has a higher frequency of words, or syllables, which lessen with a lie. Conclusion: The parameters of speech fluency did not make it possible to distinguish true speeches from liars. Studies with the largest and involving the most impacting stressors are carried out to verify whether or not the test stimulus was sufficient to change the fluency in dishonest speeches and thus ratify (or not) the results of this study.
