title: JEIDA/JCSD-Channel 0 Isolated Digits

description: <h3>Introduction</h3><br>
<p>The Japanese Electronic Industry Development Association's (JEIDA) Common Speech Data Corpus (JCSD) was prepared by Jonathan Hamaker, Richard J. Duncan and Joe Picone of the Institute for Signal and Information Processing at Mississippi State University.</p><br>
<h3>Data</h3><br>
<p>This collection consists of high-fidelity recordings of 150 native speakers of Japanese; each speaker produces four repetitions of 323 short prompts, including city names, control words, monosyllabic words, isolated digits and strings of four digits. Each reading session was recorded with two microphones, yielding two channels that differ in audio quality for each utterance. Channel 0 (<a href="http://catalog.ldc.upenn.edu/LDC96S64" rel="nofollow">LDC96S64</a>) contains data recorded with a standard dynamic microphone---a Sanken MU-2C microphone. Channel 1 (<a href="http://catalog.ldc.upenn.edu/LDC96S65" rel="nofollow">LDC96S65</a>) contains data recorded simultaneously with a condenser microphone that presumably varied from site to site and is available separately.</p><br>
<p>A summary of the size and content of the corpus is given below:</p><br>
<p>number of speakers 150 speakers males 75 females 75 range of speaker age 10 yrs. to 70 yrs. number of items per speaker 323 items isolated digits 15 four digit sequences 35 city names 100 monosyllables 110 control words (set A) 13 control words (set B) 24 control words (set C) 26 number of repetitions per item 4 repetitions total number of utterances 193,763 utterances (per channel) sample frequency 16 kHz sample type 16-bit linear number of microphones 2 (dynamic and condenser)</p><br>
<p>For purposes of publication by the LDC, the corpus was originally organized onto 40 CD-ROMs; the partitioning of the data files was done primarily by channel (20 CD-ROMs each for channel 0 and channel 1) and secondarily by category of prompts. These prompts include:</p><br>
<p>Description Number of items Control Words: Banking Services 13 Word Processors 24 Home Electronic Equipment 26 Digits: Isolated Digits 15 Four Digit Sequences 35 City Names: 100 a phonetically-rich subset of common Japanese city names Monosyllables: 110 all Japanese monosyllables plus several used to pronounce foreign words</p><br>
<p>JEIDA/JCSD-Channel 0 and JEIDA/JCSD-Channel 1 can each be ordered as complete sets. Components of the corpus can also be purchased as outlined below:</p><br>
