Switchboard-2 Phase II

<h3>Introduction</h3><br>
<p>SWB-2 Phase II consists of 4,472 five-minute telephone conversations involving 679 participants. This corpus was collected by the Linguistic Data Consortium (LDC) in support of a project on Speaker Recognition sponsored by the U.S. Department of Defense.</p><br>
<h3>Data</h3><br>
<p>Participants in SWB-2 Phase II were recruited from the following midwestern college campuses: Iowa State University, Michigan State University, University of Michigan, University of Minnesota, University of Wisconsin at Madison, Northwestern University, and Ohio State University. Solicitation methods included the Internet, newspaper advertisements and personal contacts. The majority of the participants resided in Minnesota, Wisconsin, Ohio, Iowa, Michigan and Illinois as follows:</p><br>
<p>Minnesota - 156 speakers</p><br>
<p>Wisconsin -- 105 speakers</p><br>
<p>Ohio -- 70 speakers</p><br>
<p>Iowa 64 speakers</p><br>
<p>Michigan -- 41 speakers</p><br>
<p>Illinois - 37 speakers</p><br>
<p>Each recruit was asked to participate in at least ten five-minute phone calls. Ideally each participant would receive five calls at a designated number and make five calls from phones with different (ANI) codes. Participants were asked to discuss a specific topic (read by the automated operator) and not to provide personal information during their call.</p><br>
<p>Each of the 679 participants placed their calls via a toll-free robot operator maintained by LDC. Access to the robot operator was possible via a unique Personal Identification Number (PIN) issued by the recruiting staff at LDC when the caller enrolled in the project.</p><br>
<p>Upon conclusion of the study all calls were audited by LDC staff members. Particular attention was paid to PIN verification (matching speaker with PIN), checking call duration, and call quality. Upon completion of this process, checks were issued and mailed to participants. The conversations have not been transcribed.</p><br>
