CSR-I (WSJ0) Sennheiser

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. This amounts to approximately 70 hours of speech. 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. Please note this corpus has been updated from its original disc release to a web download, some of the documentation may still reflect its original disc state. However all data is still present.

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）口语语言项目启动新型语料库构建工作，以支撑大词汇量连续语音识别（Large-vocabulary Continuous Speech Recognition, CSR）系统的相关研究。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, 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语料集的分支将采用北美商业新闻其他来源的朗读文本，最终拓展至其他新闻领域。
待朗读的文本选自WSJ语料库的5000词或20000词子集（详细信息请参见配套文档）。除朗读语音外，数据集还包含部分自发口述语音：口述语料由记者录制假想新闻文章完成，总时长约70小时。
整个数据集采集过程中使用了两款麦克风：近距离拾音的森海塞尔HMD414麦克风，以及一款可替换的辅助麦克风。因此该语料库提供三种配置版本：仅包含森海塞尔麦克风录制的语音、仅包含辅助麦克风录制的语音，以及同时包含两款麦克风录制语音的完整合集；三个版本均涵盖全部语音转写文本、测试集、文档及其他相关资源。
通常而言，语音转写文本、ARPA（Advanced Research Projects Agency）评估测试数据、各类语音识别系统的评测得分及评分所用软件，均与波形数据存储在不同的光盘介质中。
请注意，该语料库已从最初的光盘发行版本更新为网络下载版本，部分文档可能仍沿用最初的光盘发行说明，但所有数据集内容均完整保留。

背景概述

CSR-I (WSJ0) Sennheiser是一个用于大词汇量连续语音识别研究的英语语音数据集，包含约80小时的录音，由123名说话人（男女各半）使用Sennheiser HMD414麦克风录制，采样率为16kHz。数据基于《华尔街日报》文本，包括读语音和自发听写部分，专为DARPA-CSR项目设计，提供完整的正交转录和语言模型，适用于语音识别系统开发和评估。
