The judges completed auditory-perceptual judgment (APJ) and acoustic analysis of 30 transgender women and 23 transgender men, aged between 18 and 43 years, based on the production of the sustained vowel /a/ and connected speech (number counting and days of the week). The APJ was made in consensus by two judges; vocal deviation was analyzed using the GRBASI scale; the parameters pitch (high, medium, and low) loudness (strong, adequate, and weak), resonance (laryngopharyngeal, balanced, and nasal), articulation (locked, adequate, and exaggerated), intonation (descending, level, and ascending), and gender perception (feminine, masculine, and neutral). For the acoustic evaluation, the software PRAAT was used to extract the parameters oscillatory frequency (f&lt;sub&gt;o&lt;/sub&gt;), f&lt;sub&gt;o&lt;/sub&gt; deviation, minimum and maximum frequency (f&lt;sub&gt;o&lt;/sub&gt;min/f&lt;sub&gt;o&lt;/sub&gt;max), first (F&lt;sub&gt;1&lt;/sub&gt;), second (F&lt;sub&gt;2&lt;/sub&gt;), third (F&lt;sub&gt;3&lt;/sub&gt;), and fourth (F&lt;sub&gt;4&lt;/sub&gt;) formant frequencies. The Kruskal-Wallis test, chi-square test, and Fisher's exact test were used for the statistical analysis of the data. For the regression analysis, the data were analyzed descriptively and inferentially using SPSS 29.0 software. A binary logistic regression model was applied to predict the binary nominal qualitative dependent variable of gender congruence through voice. In all statistical tests, a significance level of 5% (P &lt; 0.05) was used.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The average f&lt;sub&gt;o&lt;/sub&gt; was 146.289 Hz for trans women and 157.409 Hz for trans men. For trans women, gender perception was related to the parameters pitch (P = 0.013), articulation (P = 0.017), and intonation (P = 0.000).
