Early efforts were based on the faith that speech is a string of phonemes that can be isolated and recognized one by one. This wave broke when it became clear that the physical realization of a phoneme is smeared in time and mingled with that of its neighbors, and also context and speaker-dependent. Next came the invention of the highly successful time-warping DP-matching methods in which whole words are matched by templ~tes. This wave is still going strong, at least in Japan, but it may have reached a high mark. To probe this question, we investigate the case of the \"jion\", a subset of character readings that \"generates\" a large subset of Japanese. This set has low redundancy and contains many minimal pairs. Error analysis of DP-matching shows that most errors occur between pairs that differ only in their . initial consonant, especially if it belongs to groups such as plosives or nasals. Combining DP-matching wi th limi tedscope phoneme recognition could break through present limits.","doi":null,"url":"https://ijcai.org/proceedings/1985/175","pdf":"https://ijcai.org/proceedings/1985/0175.pdf","markdown":"https://ijcai.org/proceedings/1985/175.md","bibtex":"https://ijcai.org/proceedings/1985/bibtex/175","volume":{"slug":"1985","title":"Proceedings of the Ninth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1985","url":"https://ijcai.org/proceedings/1985/","year":1985,"location":"Los Angeles, California, USA","dates":"","editors":"Aravind Joshi","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Natural Language","track":"Natural Language","number":175,"pages":{"first":883,"last":884},"keywords":[],"videos":[],"references":[{"position":1,"raw":"Repp,B.H. \"On Levels of Description in Speech Research,\" JASA 69, 1981, 1462-1464.","title":"On Levels of Description in Speech Research","authors":"B H Repp","year":"1981","venue":"JASA","doi":null,"url":null,"internal_url":null},{"position":2,"raw":"McCawley,J.D.
