Abstract
-
In Korea, the Ministry of Justice initiated an innovative pilot project---the Automated Voiceprint Recognition Supervision (AVRS) program---as a tool of intensive supervision probation for high risk juvenile probationers in 2003. The AVRS program uses individual human speech patterns and a computerized voiceprint verification system. The logic of the program is straightforward; random phone calls to juveniles' homes make juvenile probationers stay home at night, and it reduces the opportunities for youth to be involved in criminal activities. This idea is a manifestation of the situational crime prevention approach that makes criminal pathways more challenging so that potential offenders desist from crime.;This study seeks to examine the AVRS program by using official data from the 2003 pilot project. The specific aims of the study include (1) examining the effectiveness of the AVRS program, (2) investigating essential predictors of recidivism rates, and (3) comparing the characteristics of program participants and the control group to determine the proper criteria for selection eligibility.;The data are selected from the two official databases: (1) Probation and Integrated Information System (PIIS) and (2) Crime History Data (CHD). There are a total of 508 juvenile probationers in this study. The AVRS sample group is based on universal sampling method, which uses all juveniles from two probation offices (South Seoul and Su-Won) who participated in the AVRS program from April 2003 to June 2005 (N=214). The comparison group samples are selected by a random sampling method from the total juvenile probationers (N=294). In order to account for the group differences between the AVRS group and comparison group, this study uses a logistic regression (backward condition) model to estimate the odds of being assigned to the AVRS program (propensity score). Then, this study investigates the association among program assignment, demographic variables, and recidivism rates. Multiple aspects of outcome variables are included, such as duration of desistence from crime, revocation, and number of rearrests during a one-year follow-up period. In addition, by using survival analysis, this study examines the impact of the AVRS program on recidivism, especially the length of time before recidivism occurs after the program's completion.;Results suggest that generally the AVRS program is not statistically successful in reducing recidivism rates once risk factors are controlled in a one-year follow-up period. Instead, the AVRS program increases the opportunities for the juveniles to receive warning tickets and revocation during the program or probation period.
