    "title": "How to use context to disambiguate overlapping categories: The test case of Japanese vowel length",
    "subtitle": null,
    "abstract": "Infants learn the sound categories of their language and adults\nsuccessfully process the sounds they hear, even though sound\ncategories often overlap in their acoustics. Most researchers\nagree that listeners use context to disambiguate overlapping cat-\negories. However, they differ in their ideas about how context\nis used. One idea is that listeners normalize out the systematic\neffects of context from the acoustics of a sound. Another idea\nis that contextual information may itself be an informative cue\nto category membership, due to patterns in the types of contexts\nthat particular sounds occur in. We directly contrast these two\nways of using context by applying each one to the test case of\nJapanese vowel length. We find that normalizing out contextual\nvariability from the acoustics does not improve categorization,\nbut using context in a top-down fashion does so substantially.\nThis reveals a limitation of normalization in phonetic acquisi-\ntion and processing and suggests that approaches that make use\nof top-down contextual information are promising to pursue.",
