Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Acoustic and Perceptual Measurements of 3- and 4-Year Old Children's Productions of Word-Initial /ɹ/ and /w/
    (2023-05-18) Ancel, Elizabeth E; Smith, Michael L; Rao, V. N. Vimal; Munson, Benjamin; ancel014@umn.edu; Ancel, Elizabeth E; University of Minnesota Studies in the Applied Sociolinguistics of Speech and Language Lab
    This data contains acoustic and perceptual measurements of 3- and 4-year-old children's productions of /ɹ/- and /w/- initial words. Young children's production of the /ɹ/ sound is highly variable and often inaccurate, with [w] as the most common substitution error. One acoustic indicator of the goodness of children’s /ɹ/ productions is the difference between the frequency of the second formant (F2) and third formant (F3), with a smaller F3-F2 difference being associated with a perceptually more adult-like /ɹ/. This data contains both automatically extracted F3-F2 differences for the full set of 117 children, as well as manual measurements of a subset of the children (n=14). Additionally, this data contains untrained listeners' perceptual measurements of the children's productions for comparison.
