Introduction

The text component of the CALLHOME English package includes transcripts and documentation files for 120 unscripted telephone conversations between native speakers of English; a separate catalog entry, (LDC97S42) provides the speech data for these conversations, which are partitioned into separate subdirectories for "training" (80 conversations), "development test set" (20 conversations) and "evalutation test set" (20 conversations).

Data

The transcripts cover a contiguous ten minute segment of each call in the training and development test sets, and a five minute segment of each call in the evaluation set, yielding a total of 18.3 hours of transcribed spontaneous speech, comprising about 230,000 words. The transcripts are timestamped by speaker turn for alignment with the speech signal and are provided in standard orthography.

In addition to transcript files, this corpus contains full documentation on the transcription conventions and format. Complete auditing information on the speakers represented in the transcripts (including gender, channel quality and so on) is also included.

This corpus is distributed throughout the LDC's FTP server.

The corpus of telephone speech (LDC97S42) is available separately, as well as an associated lexicon (LDC97L20).
