Maximum phonation time (MPT) is frequently used by speech therapists in clinics and in surveys in the field of Voice. The description of how it is used, however, varies a lot. AIM: Compare and analyze the different ways MPT is measured in the national and international literature and check if these variations interfere in the final results. METHODS: the thesis comprehends three studies. The first study is a review on how MPT is measured and standardized in the international literature. The second study checks Brazilian literature for the way MPT is measured applying: the sound used; the patient’s position; the assessor’s given order; the type of instruments used and the final average calculation. The third study, based on the second study, establishes four sequences of measurement. These sequences were tested in 60 adults (30 men and 30 women) aged between 18 and 45. RESULTS: in the first study, it was observed that the description of the MPT measurement method doesn’t show clearly all the steps of the process. Besides, the standardization is related to the population of each country. In the national surveys of the second study, what stands out is: the use of vowels (89%); placing the patient standing up (41.8%) and the choice of a longer time for three emissions for the final calculation (30,9%). While testing the sequences in the third study, it was observed a relevant difference in the MPT numbers for men and women and there was no relevant difference in the four sequences. CONCLUSION: in the International literature, it was observed that the process of measurement carried out was not fully described; moreover, the standardization was according to each reality and many times, outdated. In the national literature, it was observed that what was more frequent in the surveys was the use of vowels and the choice of a longer time for three emissions in the MPT final calculation. The data resulting from the different ways of measuring show similarity in relation to how you place the patient and the way the final measurement is calculated
