CALLFRIEND Farsi Second Edition Speech was developed by the Linguistic Data Consortium (LDC) and consists of approximately 42 hours of telephone conversation (100 recordings) among native Farsi speakers. The calls were recorded in 1995 and 1996 as part of the CALLFRIEND collection, a project designed primarily to support research in automatic language identification. One hundred native Farsi speakers living in the continental United States each made a single telephone call, lasting up to 30 minutes, to a family member or friend living in the United States.
This release represents all calls from the collection. LDC released recordings from 60 calls without transcripts in 1996 as CALLFRIEND Farsi (LDC96S50) after 20 of those calls were used as evaluation data in the first NIST Language Recognition Evaluation (LRE). Seven of these original 60 calls were deemed unsuitable for transcription and, thus 53 of the original CF Farsi files are included along with 47 new files.
Corresponding transcripts are available in CALLFRIEND Farsi Second Edition Speech Transcripts (LDC2014T01).
All recordings involved domestic calls routed through the automated telephone collection platform at LDC and were stored as 2-channel (4-wire), 8-KHz mu-law samples taken directly from the public telephone network via a T-1 circuit. Each audio file is a FLAC-compressed MS-WAV (RIFF) format audio file containing 2-channel, 8-KHz, 16-bit PCM sample data.
This release includes speaker information, including gender, the number of speakers on each channel and call duration.
