The Corpus of Spontaneous Japanese spoken by non-native speakers is a large-scale annotated corpus for spoken language research. Corpus has been focused on as new language research data, which was established with high quality on a large scale. Most of the corpora, however, aim at the speech of native speakers, and few at non-native speakers. Our research, paying attention to such speech of non-native speakers, has established a large-scale annotated corpus. This corpus could show phonetic features in speech of non-native speakers, and furthermore provide research of interlanguage and sociolinguistics with beneficial data.The Corpus of Spontaneous Japanese spoken by non-native speakers contains about 2000 minutes of spontaneous speech that correspond to about 360k words. All these speech material are recorded using head-worn close-talking microphones and DAT, and down-sampled to 16kHz, 16bit accuracy. The speech material is transcribed using a two-way transcription scheme designed especially for CSJ (the Corpus of Spontaneous Japanese).Recorded speech is transcribed in two different ways: orthographic and phonetic transcriptions. In "orthographic" transcription, speech is transcribed using Kanji (Chinese logograph) and Kana (Japanese syllabary) just like ordinary Japanese text, but unlike the ordinary Japanese writing, our orthographic transcription has rigorous rules about the usage of Kanji and Kana letters.Part of the corpus is segment labeled. The labels are basically phonemic, but some phonetic labels are used, too. Phonetic labels are introduced for the study of phonetic variation and spontaneous speech-specific phenomena.5 utterances are also intonation labeled with X-JToBI. In the scheme of X-JToBI both the tone and BI (boundary index) labels were considerably extended to match the paralinguistic features of the spontaneous speech intonation.

非母语者自发日语语料库是一个大规模的口语研究语料库。语料库作为一种新型的语言研究数据，大规模高质量地建立起来，受到了人们的关注。然而，大部分语料库都是针对本族语者的，而针对非本族语者的语料库却很少。我们的研究关注非本族语者的这类言语，建立了一个大规模的标注语料库。该语料库能够反映非母语者的语音特征，为中介语和社会语言学的研究提供有益的数据。非母语者的自发日语语料库包含约2000分钟的自发语音，对应约36万个单词。所有这些语音材料都是使用头戴式近距离说话麦克风和DAT记录的，并下采样到16 kHz，16位精度。语音材料的转录使用了专门为CSJ（The Corpus of Spontaneous Japanese）设计的双向转录方案。在“正字法”转录中，语音像普通日语文本一样使用汉字和假名进行转录，但与普通日语文字不同的是，我们的正字法转录对汉字和假名字母的使用有严格的规则。标签基本上是音素的，但也使用了一些语音标签。语音标签的引入是为了研究语音变异和自发的言语特异性现象。5个话语也被标注了语调X-JToBI。在X-JToBI方案中，声调和BI（边界指数）标签都被大大扩展，以匹配自发语音语调的非语言学特征。
