Purpose: to verify, with the auditory-perceptual and acoustic parameters, the occurrence of voice changes in children with no voice complaints, per sex.  Methods: the registers of 36 children with no voice complaints, aged 6 to 8 years, of whom 19 were males, were assessed. The databank consisted of the recordings of sustained vowels, sentences, and spontaneous speech. The auditory-perceptual analysis was conducted with the Consensus Auditory-Perceptual Evaluation of Voice, and the acoustic analysis, with VoxMetria. The fundamental frequency, jitter, shimmer, noise, and glottal-to-noise excitation ratio were analyzed. The Mann-Whitney test was applied for numerical variables, and the McNemar test, for the categorical ones, at the p &lt; 0.05 significance level.  Results: of the 5 children with mild voice changes, 4 were males. The most frequent resonance deviation was the laryngopharyngeal one. There was no difference between the sexes in the auditory-perceptual findings. The fundamental frequency in the group with changes was lower than that in the group without changes. There was a statistical association between the changes in the auditory-perceptual assessment and the acoustic parameters.  Conclusion: voice changes occurred in 13.89% of the studied sample of children with no voice complaints, without differences between the sexes in the auditory-perceptual parameters. Vocal deviations were in a mild degree in all children who had them, the most frequent ones being roughness and breathiness. The fundamental frequency and shimmer were the acoustic parameters whose values most often occurred outside the reference limits, in both genders.
