The Japanese Electronic Industry Development Associations (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.


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 (LDC96S64) contains data recorded with a standard dynamic microphone---a Sanken MU-2C microphone. Channel 1 (LDC96S65) contains data recorded simultaneously with a condenser microphone that presumably varied from site to site and is available separately.

A summary of the size and content of the corpus is given below:
