Description:		*Introduction* Switchboard Cellular Part 2 Audio was developed by the Linguistic Data Consortium (LDC) and consists of approximately 200 hours of English telephone conversations collected by LDC in 2000. The Switchboard cellular collection focused primarily on cellular phone technology of all service types. The goal was to target 200 subjects balanced by gender to participate in 10 or more five- to six-minute conversations on cellular phones. The speech data was collected for research, development, and evaluation of automatic systems for speech-to-text conversion, speaker identification, language identification, and speech signal detection purposes. *Data* During the study period, LDC collected a total of 2,020 calls, or 4,040 sides (2,950 cellular). Here is a gender breakdown of the participant pool and call sides collected: Gender Participants Sides Female 250 2,405 Male 169 1,635 Total 419 4,040 Each speech file consists of a 1,024-byte ASCII-formatted Sphere header, followed by two-channel interleaved mu-law sample data. The mu-law samples represent the actual digital data transmission from the telephone service provider (MCI), as captured separately for each side of the telephone conversation by LDC's telephone collection platform. The header also indicates the caller_pin, callee_pin, topic_id, cellular service/handset information and speaker demographic information. The data files are not compressed. This release contains speech data files with documentation describing speaker information (sex, age, education, city and state where raised), call information (date, time, call duration, Personal Identification Numbers, topic), and audit information (channel quality, background noise). The documentation also contains reports on clipped files.
