Our model builds on earlier models of unsupervised phone-like unit discovery from acoustic data (Lee and Glass, 2012), and unsupervised symbolic lexicon discovery using the Adaptor Grammar framework (Johnson et al., 2006), integrating these earlier approaches using a probabilistic model of phonological variation. We show that the model is competitive with state-of-the-art spoken term discovery systems, and present analyses exploring the model\u2019s behavior and the kinds of linguistic structures it learns.<\/jats:p>","DOI":"10.1162\/tacl_a_00146","type":"journal-article","created":{"date-parts":[[2018,12,28]],"date-time":"2018-12-28T15:44:35Z","timestamp":1546011875000},"page":"389-403","source":"Crossref","is-referenced-by-count":42,"title":["Unsupervised Lexicon Discovery from Acoustic Input"],"prefix":"10.1162","volume":"3","author":[{"given":"Chia-ying","family":"Lee","sequence":"first","affiliation":[{"name":"Computer Science and Artificial Intelligence Laboratory, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy J.","family":"O\u2019Donnell","sequence":"additional","affiliation":[{"name":"Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Glass","sequence":"additional","affiliation":[{"name":"Computer Science and Artificial Intelligence Laboratory, Massachusetts Institute of Technology, Cambridge, MA 02139, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"issue":"24","key":"p_3","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1016\/S0167-6393(99)00033-3","volume":"29","author":"Bacchiani M","year":"1999","journal-title":"Speech Communication"},{"key":"p_4","first-page":"93","volume":"2","author":"B\u00f6rschinger Benjamin","year":"2014","journal-title":"Transactions of ACL"},{"key":"p_5","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1023\/A:1007541817488","volume":"34","author":"Brent Michael R.","year":"1999","journal-title":"Machine Learning"},{"issue":"8","key":"p_6","doi-asserted-by":"crossref","first-page":"294","DOI":"10.1016\/S1364-6613(99)01350-9","volume":"3","author":"Brent Michael R.","year":"1999","journal-title":"Trends in Cognitive Sciences"},{"issue":"4","key":"p_8","doi-asserted-by":"crossref","first-page":"327","DOI":"10.1080\/00031305.1995.10476177","volume":"49","author":"Chib Siddhartha","year":"1995","journal-title":"The American Statistician"},{"issue":"4","key":"p_11","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1109\/TASSP.1980.1163420","volume":"28","author":"Davis Steven B.","year":"1980","journal-title":"IEEE Transactions on Acoustics, Speech, and Signal Processing"},{"issue":"2","key":"p_16","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1214\/aos\/1176342360","volume":"1","author":"Ferguson T.S.","year":"1973","journal-title":"Ann.
