Speech in Noisy Environments (SPINE2) Part 1 Transcripts

Introduction This corpus was used as part of the training set for the Second Speech in Noisy Environments Evaluation (SPINE2). SPINE2 provides a continuing forum for assessing the state of the art and practice in speech recognition technology for noisy military environments and for exchanging information on innovative speech recognition technology in the context of fully implemented systems that perform realistic tasks. The evaluation will provide researchers, potential sponsors, and customers with a quantitative means to appreciate the strengths and weaknesses of the technologies. Also, the results reported on will invite customer interest in the potential utility of the technologies. More information on this evaluation is available here. This work was sponsored in part by National Science Foundation Grant No. ISS-9982201. Data This publication contains the Speech in Noisy Environments 2 (SPINE2) Training Transcripts, created for the Department of Defense (DoD) Digital Voice Processing Consortium (DDVPC) by Arcon Corp., and produced by the Linguistic Data Consortium (LDC) as catalog number LDC2001T05 with ISBN 1-58563-207-4. The audio for this publication is available as Speech in Noisy Environments (SPINE2) Training Audio LDC2001S04, ISBN 1-58563-206-6. These corpora support the 2001 Speech in Noisy Environments evaluation. The training data comprises two talker pairs (four speakers total) with 32 conversations (sessions) per talker pair (64 conversations total). The audio for each session is presented in three forms: Unprocessed: the signal recorded at the participant's microphone Bitstream: the compressed "channel" data produced by the vocoder's analysis stage for transmission from sender to receiver Processed: the signal produced by the vocoder's synthesis stage, given the bitstream data as input. There are a total of 64 clean audio files and 64 vocoded files, one "game" each, for a rough total of seven hours of audio data, 1.6Gb (including the unprocessed, the processed, and the bitstream files), 20,850 total tokens (730 unique tokens).

引言
本语料库曾作为第二届嘈杂环境语音识别评测（Second Speech in Noisy Environments Evaluation，SPINE2）训练集的组成部分。SPINE2搭建了持续性交流平台，用于评估面向嘈杂军用场景的语音识别技术的当前水平与实践应用，并针对已落地执行真实任务的系统中的创新语音识别技术开展信息交换。本次评测将为研究人员、潜在资助方与客户提供量化手段，以明晰各类技术的优劣之处；同时，公开的评测结果也将吸引客户关注相关技术的潜在应用价值。如需了解本次评测的更多信息，可访问此处。本研究部分由美国国家科学基金会 (National Science Foundation) 资助，项目编号ISS-9982201。

数据
本出版物包含《嘈杂环境语音2训练转录文本》（Speech in Noisy Environments 2 Training Transcripts，SPINE2），由Arcon公司为美国国防部 (Department of Defense) 数字语音处理联盟 (Digital Voice Processing Consortium，DDVPC) 制作，并由语言数据联盟 (Linguistic Data Consortium，LDC) 以编目编号LDC2001T05、ISBN 1-58563-207-4正式发布。本出版物配套的音频可通过《嘈杂环境语音训练音频》（Speech in Noisy Environments Training Audio，SPINE2）获取，编目编号LDC2001S04，ISBN 1-58563-206-6。上述语料库均服务于2001年嘈杂环境语音识别评测。

训练数据包含2组说话人对（共计4名说话人），每组说话人对对应32段对话（会话），总计64段对话。每段会话的音频包含三种形式：
- 未处理版：由参与方麦克风录制的原始信号
- 比特流版：由声码器分析阶段生成的压缩“信道”数据，用于发送方与接收方之间的传输
- 处理版：以比特流数据为输入，经由声码器合成阶段生成的信号

本次数据集总计包含64个纯净音频文件与64个声码处理后的音频文件，每个对应一段任务会话，总音频时长约7小时，总数据量1.6Gb（涵盖未处理版、处理版与比特流文件），共计20850个Token（其中730个为唯一Token）。
