CALLFRIEND Egyptian Arabic Second Edition

<h3>Introduction</h3><br> <p>CALLFRIEND Egyptian Arabic Second Edition was developed by the Linguistic Data Consortium (LDC) and consists of approximately 25 hours of unscripted telephone conversations between native speakers of Egyptian Arabic. This second edition updates the audio files to wav format, simplifies the directory structure and adds documentation and metadata. The first edition is available as CALLFRIEND Egyptian Arabic (<a href="../../../LDC96S49">LDC96S49</a>).</p><br> <p>The CALLFRIEND series is a collection of telephone conversations in several languages conducted by LDC in support of language identification technology development. Languages covered in the collection include American English, Canadian French, Egyptian Arabic, Farsi, German, Hindi, Japanese, Korean, Mandarin Chinese, Spanish, Tamil and Vietnamese.</p><br> <h3>Data</h3><br> <p>All data was collected before July 1997. Participants could speak with a person of their choice on any topic; most called family members and friends. All calls originated in North America. The recorded conversations last up to 30 minutes.</p><br> <p>The data was recorded as 8kHz u-law SPH encoded stereo files, with one end of the phone call on each channel. In this release, files were converted to WAV format, and information from the original SPH headers is described in the documentation. SPH files are not included in this second edition.</p><br> <p>The audio files were originally split into train, dev and test folders of 20 recordings each, but they are combined in this release.</p><br> <p>Completed calls passed through a human auditing process to verify that the target language was spoken by the participants, to check the quality of the recordings, and to record information about dialect, noise and distortion.</p><br> <h3>Samples</h3><br> <p>Please listen to this <a href="desc/addenda/LDC2019S04.wav">sample</a>.</p><br> <h3>Updates</h3><br> <p>None at this time.</p></br> Portions © 1996, 1997, 2019 Trustees of the University of Pennsylvania<h3>引言</h3><br><p>CALLFRIEND埃及阿拉伯语第二版由语言数据联盟（Linguistic Data Consortium，简称LDC）研发，包含约25小时的埃及阿拉伯语母语者之间的非脚本电话对话。本第二版将音频文件更新为WAV格式，简化了目录结构，并新增了文档与元数据。第一版以《CALLFRIEND埃及阿拉伯语》（<a href="../../../LDC96S49">LDC96S49</a>）形式发布。</p><br><p>CALLFRIEND系列由语言数据联盟（LDC）为支撑语言识别技术研发打造，汇集了多语种电话对话数据集。该系列涵盖的语种包括美式英语、加拿大法语、埃及阿拉伯语、波斯语、德语、印地语、日语、韩语、普通话、西班牙语、泰米尔语以及越南语。</p><br><h3>数据说明</h3><br><p>所有数据采集于1997年7月之前。参与者可与自选对象就任意话题进行通话，多数通话对象为家人与朋友。所有通话均始发于北美，单段录音对话时长最长可达30分钟。</p><br><p>原始数据采用8kHz μ律（u-law）SPH编码立体声格式录制，每个声道分别对应通话双方的音频。本发布版已将文件转换为WAV格式，原始SPH文件头中的相关信息已在文档中说明。本第二版不包含原始SPH文件。</p><br><p>原始音频文件原本分为训练集（train）、开发集（dev）与测试集（test）三个文件夹，每个文件夹包含20条录音，但本发布版已将三者合并。</p><br><p>所有完成的通话均经过人工审核流程，用于验证参与者使用的目标语言是否符合要求、检查录音质量，并记录方言、噪音与失真情况等相关信息。</p><br><h3>样本示例</h3><br><p>请收听此<a href="desc/addenda/LDC2019S04.wav">示例音频</a>。</p><br><h3>更新说明</h3><br><p>暂无更新。</p><br><p>部分内容 © 1996、1997、2019 宾夕法尼亚大学托管委员会</p>
