Speech in Noisy Environments (SPINE2) Part 1 Audio

Introduction Speech in Noisy Environments (SPINE2) Part 1 Audio was used as part of the training set for the Second Speech in Noisy Environments Evaluation (SPINE2). SPINE2 provided 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 provided researchers, potential sponsors, and customers with a quantitative means to appreciate the strengths and weaknesses of the technologies. This work was sponsored in part by National Science Foundation Grant No. IIS-9982201. Data This publication contains the Speech in Noisy Environments 2 (SPINE2) Clean and Vocoded Training Audio Corpus created for the Department of Defense (DoD) Digital Voice Processing Consortium (DDVPC) by Arcon Corp. The transcripts for this publication are available as Speech in Noisy Environments (SPINE2) Training Transcripts LDC2001T05. For an example transcript, please click here. These corpora supported 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). Samples Please view this unprocessed audio sample and processed audio sample. Updates There are no updates at this time. Portions © 2001 Trustees of the University of Pennsylvania

嘈杂环境下语音导论（SPINE2）第一部分音频 曾作为第二届嘈杂环境下语音评估（SPINE2）训练集的组成部分。SPINE2搭建了长效专业交流论坛，用于评估面向嘈杂军事场景的语音识别技术的当前技术水平与实践应用现状，并针对可执行真实任务的完整落地系统中的创新语音识别技术开展信息交流。本次评估为研究人员、潜在资助方及客户提供了量化评估手段，用以明晰相关技术的优势与不足。本项目部分由美国国家科学基金会（National Science Foundation）资助项目编号IIS-9982201支持。

数据集说明 本出版物包含由Arcon公司为美国国防部（Department of Defense, DoD）数字语音处理联盟（Digital Voice Processing Consortium, DDVPC）制作的《嘈杂环境下语音2（SPINE2）纯净与编码训练音频语料库》。本出版物配套的语音转写文本可通过《嘈杂环境下语音（SPINE2）训练转写文本 LDC2001T05》获取，示例转写文本请点击此处。上述语料库支撑了2001年嘈杂环境下语音评估任务。训练数据涵盖2组说话人对（总计4名发言者），每组说话人对包含32段对话会话，整体共计64段对话会话。每段会话的音频包含三种格式：
未处理版：由参与者麦克风录制的原始音频信号
比特流版：由声码器分析阶段生成的压缩信道数据，用于发送端至接收端的信号传输
处理版：以比特流数据为输入，经声码器合成阶段生成的音频信号
本数据集总计包含64个纯净音频文件与64个编码音频文件，每个会话对应一组文件，总音频时长约7小时，总数据量1.6Gb（包含未处理版、处理版与比特流文件），总计20850个Token（Token），其中730个为唯一Token。

示例音频 请查看本未处理音频示例与处理后音频示例。
