CALLHOME American English Speech was developed by the Linguistic Data Consortium (LDC) and consists of 120 unscripted 30-minute telephone conversations between native speakers of English. All calls originated in North America; 90 of the 120 calls were placed to various locations outside of North America, while the remaining 30 calls were made within North America. Most participants called family members or close friends. This corpus contains speech data files with documentation describing their contents and format along with the software packages needed to uncompress the speech data. Corresponding transcripts and documentation are available separately, as is an associated lexicon (LDC97L20).
