Speech in Noisy Environments (SPINE2) Part 2 Audio

Introduction Speech in Noisy Environments (SPINE2) Part Audio was used as the development 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 release contains the Speech in Noisy Environments 2 (SPINE2) Clean and Vocoded Development 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) Development Transcripts LDC2001T07. For an example transcript, please click here. These corpora supported the 2001 Speech in Noisy Environments evaluation. The development data comprises two talker pairs (four speakers total) with 16 conversations (sessions) per talker pair (32 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 32 clean audio files and 32 vocoded files, one "game" each, for a rough total of three and a half hours (207 minutes) of audio data, 811Mb (including the unprocessed, the processed, and the bitstream files), 9,700 total tokens (600 unique tokens). Samples Please view this unprocessed sample and processed sample. Updates There are no updates at this time. Portions © 2001 Trustees of the University of Pennsylvania

嘈杂环境下语音（SPINE2）开发集音频被用作第二届嘈杂环境下语音评测（SPINE2）的开发集。SPINE2搭建了持续性交流平台，用于评估面向嘈杂军事环境的语音识别技术的当前水平与实践应用，并针对可执行真实任务的成熟落地系统中的创新语音识别技术开展信息交换。本次评测为研究人员、潜在资助方与客户提供了量化手段，以评估各类技术的优势与不足。本研究部分由美国国家科学基金会资助，项目编号为IIS-9982201。

数据集详情
本次发布的数据集包含由Arcon公司为美国国防部（DoD）数字语音处理联盟（DDVPC）打造的嘈杂环境下语音2（SPINE2）干净语音与声码化语音开发音频语料库。本次发布数据集的转录文本可通过《嘈杂环境下语音（SPINE2）开发转录文本LDC2001T07》获取。如需查看转录文本示例，请点击此处。该语料库为2001年嘈杂环境下语音评测提供了数据支撑。
开发集包含2组说话人对（共4名说话人），每组说话人对对应16段对话（会话），总计32段对话。每段会话的音频包含三种形式：
1. 未处理音频：由参与者麦克风录制的原始信号
2. 比特流数据：由声码器分析阶段生成的压缩“信道”数据，用于发送方至接收方的传输
3. 处理后音频：以比特流数据为输入，经声码器合成阶段生成的信号
本次数据集共包含32个干净音频文件与32个声码化音频文件，每段对应一个“任务场景”，总音频时长约3.5小时（207分钟），总数据量为811Mb（包含未处理音频、处理后音频与比特流文件），总Token（Token）数达9700个，其中唯一Token（Token）为600个。
