The Switchboard Telephone Speech Corpus is a corpus of spoken English language consisted of almost 260 hours of speech. It was created in 1990 by Texas Instruments via a DARPA grant, and released in 1992 by NIST. The corpus contains 2,400 telephone conversations among 543 US speakers (302 male, 241 female).[1][2][3] Participants did not know each other, and conversations were held on topics from a predetermined list.[4]
Switchboard-2 Phase II was collected in 1999 and includes "4,472 five-minute telephone conversations involving 679 participants".[5]
The corpus was used for development of speech recognition algorithms.[6]
