This file contains documentation on the Spelled and Spoken Words Corpus, Linguistic Data Consortium (LDC) catalog number LDC2006S15 and ISBN 1-58563-382-8.

The Spelled and Spoken Words corpus consists of spelled and spoken words. 3,647 callers were prompted to to say and spell their first and last names, to say what city they grew up in and what city they were calling from, and to answer two yes/no questions. In order to collect sufficient instances of each letter, 1,371 callers also recited the English alphabet with pauses between the letters. Each call was transcribed by two people, and all differences were resolved. In addition, a subset of 2,648 calls has been phonetically labeled.


For an example of the data in this corpus, please listen to this audio sample.
