CSLU: Kids` Speech Version 1.1

<h3>Introduction</h3><br>
<p>CSLU: Kids' Speech Version 1.1 , Linguistic Data Consortium (LDC) catalog number LDC2007S18 and isbn 1-58563-395-X, is a collection of spontaneous and prompted speech from 1100 children between Kindergarten and Grade 10 in the Forest Grove School District in Oregon. All children -- approximately 100 children at each grade level -- read approximately 60 items from a total list of 319 phonetically-balanced but simple words, sentences or digit strings. Each utterance of spontaneous speech begins with a recitation of the alphabet and contains a monologue of about one minute in duration. This release consists of 1017 files containing approximately 8-10 minutes of speech per speaker. Corresponding word-level transcriptions are also included.</p><br>
<p>This corpus was developed to facilitate research about the characteristics of children's speech at different ages and to train and evaluate recognizers for use in language training and other interactive tasks involving children, including to train recognizers used in language development with deaf children.</p><br>
<h3>Data</h3><br>
<p>Data collection was performed using the <a href="http://www.cslu.ogi.edu/toolkit/" rel="nofollow">CSLU Speech Toolkit</a> and two computers running Windows NT 4.0. Each computer was manned by a CSLU staff member who monitored progress and helped the child with any difficulties. The average time at the computer was 20 minutes, yielding approximately 8-10 minutes of speech digitized at 16 bits and 16kHz using Soundblaster 16 PnP audio cards with head-mounted microphones.</p><br>
<p>The prompted speech, consisting of 200 isolated words and 10 numeric strings, was presented as text appearing below an animated character that produced accurate visible speech synchronized with recorded prompts. A text prompt was also displayed. The child then reproduced the prompted word. Once the prompted speech collection was completed, the experimenter then asked the subject a series of questions designed to elicit spontaneous speech (i.e "Tell me about your favorite movie").</p><br>

<h3>引言</h3><br>
<p>CSLU儿童语音数据集（版本1.1）由语言数据联盟（Linguistic Data Consortium，LDC）以目录号LDC2007S18及ISBN 1-58563-395-X发布，该数据集收录了俄勒冈州森林格罗夫学区1100名幼儿园至十年级儿童的自发语音与提示性语音。每个年级约有100名儿童参与，他们需从包含319个语音平衡但简洁的单词、句子或数字串的总列表中朗读约60个条目。每一段自发语音均以字母表朗诵开篇，时长约为一分钟的独白。本次发布包含1017个音频文件，每位说话者对应约8至10分钟的语音数据，同时附带对应的词级转录文本。</p><br>
<p>本语料库的构建旨在助力不同年龄段儿童语音特征的相关研究，同时可用于训练与评估语音识别器，以应用于儿童语言训练及其他涉及儿童的交互任务，包括训练用于听障儿童语言发展的语音识别器。</p><br>
<h3>数据</h3><br>
<p>数据采集采用<a href="http://www.cslu.ogi.edu/toolkit/" rel="nofollow">CSLU语音工具包</a>与两台运行Windows NT 4.0的计算机完成。每台计算机由一名CSLU工作人员值守，负责监控采集进度并协助儿童解决遇到的问题。儿童平均上机时长为20分钟，最终采集到约8至10分钟的语音数据，语音以16位采样精度、16kHz采样率进行数字化，采集设备为搭载头戴式麦克风的Soundblaster 16 PnP音频卡。</p><br>
<p>提示性语音部分包含200个孤立单词与10个数字串，展示形式为动画角色下方的文本，该角色会生成与录制提示同步的精准可视口型动画，同时屏幕上也会显示文本提示。儿童需复现提示的语音内容。完成提示性语音采集后，实验人员会向受试者提出一系列问题，以引导其产生自发语音（例如“谈谈你最喜欢的电影”）。</p><br>
