收藏资源简介：
<h3>Introduction</h3><br> <p>IARPA Babel Lithuanian Language Pack IARPA-babel304b-v1.0b was developed by <a href="http://www.appen.com/">Appen</a> for the IARPA (Intelligence Advanced Research Projects Activity) <a href="http://www.iarpa.gov/index.php/research-programs/babel">Babel</a> program. It contains approximately 210 hours of Lithuanian conversational and scripted telephone speech collected in 2013 and 2014 along with corresponding transcripts.</p><br> <p>The Babel program focuses on underserved languages and seeks to develop speech recognition technology that can be rapidly applied to any human language to support keyword search performance over large amounts of recorded speech.</p><br> <h3>Data</h3><br> <p>The Lithuanian speech in this release represents that spoken in the Aukštaitian and Samogitian dialect regions of Lithuania. The gender distribution among speakers is approximately equal; speakers' ages range from 16 years to 71 years. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments including the street, a home or office, a public place, and inside a vehicle.</p><br> <p>Audio data is presented as 8kHz 8-bit a-law encoded audio in sphere format and 48kHz 24-bit PCM encoded audio in wav format. Transcripts are encoded in UTF-8. Further information about transcription methodology is contained in the documentation accompanying this release.</p><br> <p>Evaluation data is available from <a href="http://www.nist.gov/">NIST</a> in support of <a href="http://www.nist.gov/itl/iad/mig/openkws.cfm">OpenKWS</a>.</p><br> <h3>Samples</h3><br> <p>Please view this <a href="desc/addenda/LDC2019S03.sph">audio sample</a> and <a href="desc/addenda/LDC2019S03.txt">transcript sample</a>.</p><br> <h3>Updates</h3><br> <p>None at this time.</p></br> Portions © 2015 U.S. Government</br> </br>The U.S. Government acquired this data from Appen Pty Ltd, which assigned the copyright to the data to the U.S. Government.
