CSR-I (WSJ0) Other

LDC93S6A - Complete CSR-I corpus LDC93S6B - CSR-I Sennheiser speech LDC93S6C - CSR-I other speech During 1991, the DARPA Spoken Language Program initiated efforts to build a new corpus to support research on large-vocabulary Continuous Speech Recognition (CSR) systems. The first two CSR Corpora consist primarily of read speech with texts drawn from a machine-readable corpus of Wall Street Journal news text and are thus often known as WSJ0 and WSJ1. (Later sections of the CSR set of corpora, however, will consist of read texts from other sources of North American business news and eventually from other news domains). The texts to be read were selected to fall within either a 5,000-word or a 20,000-word subset of the WSJ text corpus. (See the documentation for details). Some spontaneous dictation is included in addition to the read speech. The dictation portion was collected using journalists who dictated hypothetical news articles. Two microphones are used throughout: a close-talking Sennheiser HMD414 and a secondary microphone, which may vary. The corpora are thus offered in three configurations: the speech from the Sennheiser, the speech from the other microphone and the speech from both; all three sets include all transcriptions, tests, documentation, etc. In general, transcriptions of the speech, test data from ARPA evaluations, scores achieved by various speech recognition systems and software used in scoring are included in seperate folders from the waveform data. Updates This corpus has been updated to be contained as a single web download. The directory structure of the original CDs has been maintained.

LDC93S6A —— 完整CSR-I语料库；LDC93S6B —— CSR-I 森海塞尔（Sennheiser）语音数据集；LDC93S6C —— CSR-I 其他语音数据集。
1991年，美国国防高级研究计划局（Defense Advanced Research Projects Agency, DARPA）启动口语语言项目，着手构建新型语料库以支撑大词汇量连续语音识别（Large-vocabulary Continuous Speech Recognition, CSR）系统的研究工作。首批两款CSR语料库主要采用从机器可读《华尔街日报》（Wall Street Journal，简称WSJ）新闻语料库中提取文本的朗读语音，因此常被称为WSJ0与WSJ1。（不过后续CSR系列语料库将采用北美商业新闻其他来源的朗读文本，最终扩展至其他新闻领域）。
待朗读的文本选自WSJ语料库的5000词或20000词子集，详细信息请参阅对应文档。除朗读语音外，数据集还包含部分自发口述语音：口述部分由记者录制假想新闻文章完成。
全程使用两款麦克风：近距离拾音的森海塞尔HMD414麦克风，以及一款可更换的辅助麦克风。因此该语料库提供三种配置方案：仅森海塞尔麦克风采集的语音、仅辅助麦克风采集的语音，以及二者的合集；所有三个数据集均包含完整的转录文本、测试集、文档等内容。
一般而言，语音转录文本、ARPA评估测试数据集、各类语音识别系统的评测得分以及评分所用软件，均与波形数据分别存放于独立文件夹中。
更新说明
本语料库已更新为可单次网页下载的完整包，保留了原始光盘的目录结构。
