File: spkrinfo.doc ------------------ The file "spkrinfo.tbl" presents all the information available regarding speaker demographics. The fields in this table are described below. (The "caller" is the person who initiated the call, and whose voice appears on channel A of the speech and transcripts.) Note that there is no information available about the callee (the speaker on channel B). Field# Content ------------------- 1 Call-ID (four digits, as they appear in data file names) 2 Gender of caller (M or F) 3 Age of caller 4 Years of education completed by caller 5 Where raised 6 Country-code or area-code plus first three digits of telephone number dialed (last four digits of number are encrypted as three letters) The telephone number that was dialed has been encrypted in such a way as to provide anonymity, while still preserving the identity of each number -- if the same phone number occurs twice in the collection, it is rendered as the same alphanumeric string. All calls in this collection are US-domestic calls. Alexandra Canavan Linguistic Data Consortium January, 1998
