Using artificial intelligence to simulate the process of learning Japanese accent rules: Toward the integration of accent into the grammar curriculum

在上一财年，我们开始对语料库的口音注释(两个人+两个机器，每句话)进行系统的比较，并通过咨询一位受过语音培训的东京日语母语人士来解决由此产生的任何分歧。这项工作在本财政年度完成，因此数据库中的所有26,000多个条目现在都已手工更正。在这项工作进行期间，对Chamame的四种口音规则(C、F、M和P)的广泛测试分三个阶段进行。首先，利用整理后的《源氏词典》对话句的语料集，从出现频率、共现频率、与词性的关系等方面分析了重音规则。其次，作为个案研究，我们不仅使用了来自玄机语料库的数据，而且还使用了《新经济日语口音词典》附录中的数据，对P规则(由前缀触发)进行了更深入的研究。第三，对Unidic(Chamame使用的口音信息词典)进行了分析，以描述所有可能的口音规则及其组合，并为每一种规则精心挑选了一个说明性例子。随着语料库的最终完成和规则系统的阐明，最初的计划是在本财政年度下半年进行学习模拟并传播结果。不幸的是，由于日本以外的公益组织改变了从属关系，它被自动要求终止赠款。然而，研究本身仍在继续，随着语料库的完成，许多令人兴奋的可能性即将出现。

In the previous fiscal year, we began conducting a systematic comparison of the corpus's accent annotations (two human + two machine for every sentence) and resolving any resulting disagreements through consultation with a phonetically-trained Tokyo Japanese native speaker. This undertaking finished during this fiscal year, and thus all 26,000+ entries in the database have now been hand-corrected.While this undertaking was ongoing, extensive testing of Chamame's four types of accent rules (C, F, M, and P) proceeded in three stages. First, using the cleaned-up dataset of sentences from the dialogues in Genki, the accent rules were analyzed in terms of frequency, co-occurrence, and relationship to part-of-speech. Second, "P" rules (triggered upon prefixation) were examined in greater depth as a case study, using not only the data from the Genki corpus but also data from the appendix to Shinmeikai Japanese Accent Dictionary. Third, Unidic (the dictionary Chamame draws on for accent information) was analyzed in order to delineate the full range of possible accent rules and combinations thereof, with a carefully-selected illustrative example for each.With the corpus finally completed and rule system thus clarified, the original plan was to run learning simulations and disseminate the results during the second half of this fiscal year. Unfortunately, due to a PI's change in affiliation to outside Japan, it was automatically required to terminate the grant. However, the research itself has continued, and with the corpus now complete, many exciting possibilities are on the horizon.
