MATERIAL Kazakh-English Language Pack

<h3>Introduction</h3>

<p>MATERIAL Kazakh-English Language Pack, Linguistic Data Consortium
Catalog Number LDC2025S03, was developed by <a
href="http://www.appen.com/">Appen</a> for the IARPA (Intelligence
Advanced Research Projects Activity)
<a href= "https://www.iarpa.gov/index.php/research-programs/material">MATERIAL</a>
(Machine Translation for English Retrieval of Information in Any Language)
program. It contains approximately 57 hours of Kazakh conversational
telephone speech, transcripts, English translations, annotations and queries.</p>
<p>The MATERIAL program focused on underserved languages with the ultimate
goal to build cross language information retrieval systems to find speech
and text content using English search queries.</p>

<h3>Data</h3>
<p>The Kazakh speech in this release represents that spoken in the Northern
and Southern dialect regions of Kazakhstan. Speakers were 18 years of age or older. 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>
<p>Transcripts cover approximately 17% of the speech data, all of which was translated into English. Further
information about transcription and translation methodologies is contained
in the documentation accompanying this release. </p>
<p>Kazakh-English Language Pack also includes English queries and their
relevance annotations. Annotators marked transcripts by query (simple,
conceptual, hybrid) and by their relevance to query search terms.</p>
<p>Speech data is presented mostly as two channel wav or single channel
sphere files, both in 8kHz A-law format. Some wav files are 48kHz PCM.
All text data is UTF-8 encoded.</p>
