ABSTRACT Purpose: to relate ultrasound images with auditory-perceptual data on vocal quality settings in adult speakers of Brazilian Portuguese. Methods: the corpus consisted of speech samples (sentences contained in the instructional material of the Vocal Profile Analysis Scheme - VPAS-PB) from seven adult subjects of both genders, recorded simultaneously by acoustic and ultrasonographic means. Data analysis was based on auditory-perceptual judgments of vocal quality and ultrasound images generated by the AAA software. Results: vocal quality settings related to the position of the tongue body and the extension of the tongue and jaw found correspondences to the contours of ultrasound images of the tongue in selected key segments (oral vowels), especially those with greater degrees of manifestation. Conclusion: there were correspondences between vocal quality settings detected in the perceptual sphere and their respective tongue body and jaw ultrasound images.
