CSR-I (WSJ0) Other

LDC93S6A - Complete CSR-I corpus LDC93S6B - CSR-I Sennheiser speech LDC93S6C - CSR-I other speech<br>
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.
<br>
<br>
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).
<br>
<br>
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.

<br>
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 on separate discs from the waveform data.

LDC93S6A——完整CSR-I语料库；LDC93S6B——CSR-I森海塞尔语音语料；LDC93S6C——CSR-I其他语音语料。

1991年，美国国防高级研究计划局（Defense Advanced Research Projects Agency, DARPA）口语语言项目启动相关工作，旨在构建可支撑大词汇量连续语音识别（Continuous Speech Recognition, CSR）系统研究的新语料库。

首批两款CSR语料库主要采用源自《华尔街日报》（Wall Street Journal, WSJ）机器可读新闻文本的朗读语音，因此常被称为WSJ0与WSJ1。（不过后续的CSR语料集将采用北美商业新闻其他来源的朗读文本，最终覆盖其他新闻领域）。

待朗读的文本选自WSJ语料库的5000词或20000词子集（详细信息参见相关文档）。除朗读语音外，语料库还包含部分即兴口述内容：口述部分由记者口述假想新闻文章采集得到。

整个数据集全程采用两种麦克风采集：近距交谈式森海塞尔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：仅森海塞尔麦克风采集的语音、仅辅助麦克风采集的语音，以及双麦克风采集的语音；三种配置均包含完整的标注文本、测试数据与文档等内容。

总体而言，语音标注文本、ARPA评估测试数据、各类语音识别系统的测试得分，以及评分所用软件，均存储于与波形数据分离的光盘介质中。

背景概述

CSR-I (WSJ0) Other Discs 1-2是DARPA口语语言项目创建的语音识别研究数据集，主要包含基于《华尔街日报》文本的朗读语音和记者自发听写内容，使用Sennheiser和另一种麦克风双通道录制。数据集包含完整的语音波形数据、转录文本和评估材料，专为哈佛大学附属机构使用而限制访问。
