Research on the Regional Difference Among Japanese Dialects and Creation of Spoken Japanese Dialect Corpus

我们记录了青森县、山形县、千叶县、爱知县、富山县、奈良县、鸟取县、香川县和福冈县等9个县的日语口语方言。研究人员记录了57名男性和77名女性演讲者在175个dat上的讲话数据。我们将一部分语音数据转录成假名字符。我们编辑收集到的数据并将其记录在cd - rom上；一小部分数据也被记录在cd上。我们对日语口语方言的声学特征进行了研究，这些声学特征反映了日语口语方言的声学特征，对日语口语方言的分段和韵律分析是有效的。我们设计了语音样本上音标序列的标记程序，并开发了一个标记系统。最近，我们发现语音中浊音辅音的鼻音化越来越少。首先，我们提取了鼻化后的声母爆破辅音的声学特征，以掌握广播演播室的实际情况，并找出客观的评价方法用于教育。我们分析了NHK播音员的鼻音/ga/，研究了区分鼻音浊音和非鼻音浊音的参数。我们记录了日本人和外国人所说的日本火车站和私营公司名称的语音数据。对1542例日语口语进行了峰频率和基频分析，建立了包含语音波的日语口语数据库。

We have recorded spoken Japanese dialects from 9 districts ofAomori, Yamagata, Chiba, Aichi, Toyama, Nara, Tottori, Kagawa, and Fukuoka prefectures. Speech data were recorded from 57 male and 77 female speakers onto 175 DATs. We transcribed a part of the speech data into Kana characters. We edited the collected data and recorded them onto CD-ROMs; a small part of the data were recorded also onto CDs.We have made studies on acoustic features which reflects acoustic aspects of distinctive features effective for segmental and prosodic analyzes of Japanese spoken dialects. We devised a procedure for labeling a sequence of phonetic symbols onto speech sample and developed a labeling system.Recently, we find less nasalization of voiced velar consonants in speech. First, we extracted acoustic features of nasalized velar plosive consonants so as to grasp the actual conditions in broadcast studios and to find out objective evaluation methods to be applied for education. We analyzed nasalized /ga/ of NHK announcers and studied the parameters for discriminating nasalized voiced velar consonants from non-nasalized ones.We recorded speech data of the names of railroad stations and private companies in Japan spoken by Japanese and foreign speakers. We made formant frequency and fundamental frequency analyzes of 1542 spoken Japanese and made their database including the speech wave.
