OBJECTIVE: To determine and correlate the results of maximum phonation time (TMF) of the phonemes / e / fricative (/ é /), / e /, / s / and / z / and relations s / z and é / e of women. MATERIAL AND METHODS: Sixty women with no laryngeal disorders, aged between 18 and 44 years (average 21.96), issued the phoneme / é /, / e /, / s / and / z / in the standing position in TMF with habitual loudness and pitch. Calculate the ratios é / e and s / z. Spearman correlation test, a significance level of 5%. RESULTS: Mean TMF: / é / = 14.35s; / e / = 14.20s, / s / = 18.04s, / z / = 17.20s. Moderate positive correlation between / é / and / s / (p = 0.0002); strong positive between / e / and / z / (p = 0.0000), weakly positive between / é / and / e / (p = 0.001), strong positive between / s / and / z / (p = 0.0000), no significant correlation between the ratios é / e and s / z. CONCLUSIONS: The correlation between / é / and / e / and between / s / and / z / can be justified by articulator features in common between each pair of phonemes, especially the point of articulation of fricatives that provides greater control of the air outlet. The correlation between / é / and / s / and between / e / and / z / can be explained, respectively, by the absence and presence of glottal adduction. There was no correlation between the ratios s / z and é / e, and contrary to expectations, because they propose to evaluate the same phenomena. This may be related to the presence of articulator constriction of fricatives which increases the TMF and does not favor adequate assessment of the control of breathing at TMF.
