Introduction

Korean Telephone Conversations Speech was produced by Linguistic Data Consortium (LDC) catalog number LDC2003S03 and ISBN 1-58563-263-5.

The telephone conversations in this corpus were originally recorded as part of the CALLFRIEND project. The CALLFRIEND Korean telephone speech was collected by Linguistic Data Consortium primarily in support of the Language Identification (LID) project, sponsored by the U.S. Department of Defense. The calls were later transcribed for use in other projects.

This publication consists of 100 telephone conversations, 49 of which were published in 1996 as CALLFRIEND Korean, while the rest of 51 are previously unexposed calls.

All 100 conversations have been transcribed and are published as Korean Telephone Conversations Transcripts.

The recorded conversations are between native speakers of Korean and last up to 30 minutes, of which the transcribed speech covers between 15 to 18 minutes. All speakers were aware that they were being recorded. They were given no guidelines concerning what they should talk about. Once a caller was recruited to participate, he/she was given a free choice of whom to call. Most participants called family members or close friends. All calls originated in either the United States or Canada.
