CSLU: Kids` Speech Version 1.1

Introduction 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. 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. Data Data collection was performed using the CSLU Speech Toolkit 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. 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"). Samples For an example of the speech in this corpus, please listen to this sample of spontaneous speech.

【引言】口语语言理解中心（CSLU）儿童语音语料库版本1.1，由语言数据联盟（Linguistic Data Consortium, LDC）以目录号LDC2007S18发布，ISBN为1-58563-395-X。该语料库收录了俄勒冈州Forest Grove学区1100名幼儿园至十年级儿童的自发与引导式语音数据。所有儿童按年级分层，每个年级约100名受试者，需从包含319个语音平衡且简洁的单词、句子或数字字符串的总列表中，朗读约60个条目。每段自发语音均以字母表朗诵开篇，时长约一分钟的独白。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，同时附带配套的词级转录文本。本语料库的开发旨在推动不同年龄段儿童语音特征的相关研究，以及训练与评估适用于语言训练及其他涉及儿童的交互任务的语音识别器，包括用于聋童语言发展的语音识别器。

【数据采集】本次数据采集采用CSLU语音工具包，以及两台运行Windows NT 4.0操作系统的计算机完成。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操作困难。每位受试者在计算机前的平均停留时长为20分钟，最终采集得到约8至10分钟的语音数据，通过搭载头戴式麦克风的Soundblaster 16 PnP音频卡，以16位采样精度、16kHz采样率进行数字化存储。引导式语音部分包含200个孤立单词与10个数字字符串，以动画角色下方的文本提示形式呈现，该动画角色会生成与录制提示同步的精准可视口型，同时同步显示文本提示，随后儿童需复现该引导式语音内容。完成引导式语音采集后，实验人员将向受试者提出一系列旨在引发自发语音的问题（例如"谈谈你最喜欢的电影"）。
