CSR-I (WSJ0) Complete

Introduction 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 on separate discs from the waveform data.

引言
LDC93S6A — 完整CSR-I语料库
LDC93S6B — CSR-I 森海塞尔（Sennheiser）语音语料库
LDC93S6C — CSR-I 其他语音语料库

1991年，美国国防高级研究计划局（Defense Advanced Research Projects Agency, DARPA）口语语言项目启动构建新语料库的工作，以支撑大词汇量连续语音识别（Continuous Speech Recognition, CSR）系统的相关研究。首批两款CSR语料库的主体内容为朗读语音，其文本源自机器可读的《华尔街日报》（Wall Street Journal, WSJ）新闻语料库，因此常被称为WSJ0与WSJ1。（不过后续的CSR语料集子集将采用北美商业新闻其他来源的朗读文本，最终覆盖至其他新闻领域）。

待朗读的文本选自WSJ语料库的5000词或20000词子集（详细信息请参阅相关文档）。本语料库除包含朗读语音外，还收录了部分自发口述语音。口述语音部分由记者口述假想新闻文章的方式采集获得。

本次采集全程使用两种麦克风：近距离拾音的森海塞尔HMD414，以及一款可更换的辅助麦克风。因此本语料库提供三种配置版本：森海塞尔采集的语音、辅助麦克风采集的语音，以及二者的合集；三类数据集均包含完整的转录文本、测试集、文档资料等。

通常而言，语音转录文本、ARPA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。

背景与挑战

背景概述

CSR-I (WSJ0) Complete 是一个用于大规模词汇连续语音识别研究的英语语音数据集，包含约141小时的语音录音，来自123名说话者阅读《华尔街日报》摘录，并附带完整的正交转录和语言模型。数据采用双麦克风录制，音频格式为单通道、16位、16 kHz，旨在支持语音识别系统的开发和评估。
