    "subtitle": null,
    "abstract": "Speech perception requires ongoing perceptual category learning.\nEach talker speaks differently, and listeners need to learn\neach talker’s particular acoustic cue distributions in order to\ncomprehend speech robustly from multiple talkers. This phonetic\nadaptation is a semi-supervised learning problem, because\nsometimes a particular cue value occurs with information\nthat labels the talker’s intended category for the listener,\nbut other times no such labels are available. Previous work has\nshown that adaptation can occur in both purely supervised (all\nlabeled) and purely unsupervised (all unlabeled) settings, but\nthe interaction between them has not been investigated. We\ncompare unsupervised with (semi-) supervised phonetic adaptation\nand find, surprisingly, that adult listeners do not take advantage\nof labeling information to adapt more quickly or effectively,\neven though the labels affect their categorization. This\nsuggests that, like language acquisition, phonetic adaptation in\nadults is dominated by unsupervised, distributional learning.",
