The conference kicked off Friday evening with six workshops held in two computer labs in the very modern Building 8. For the first one, I choose Brian Teaman’s machine-aided spoken language evaluation (MASLE) presentation. The system is designed so that students can record their voices on their computers according to some predefined texts. Then the results can be evaluated in one or two ways: by hand by the teacher or other evaluator, or by machine. Brian has added a speech recognition engine to check student recordings. Evaluating with the group at the presentation, the sample of ten recordings took us just under 5 minutes to do ‘by hand.’ The machine evaluation took about 2 seconds! The output still needs to be massaged into a readable form, and the machine’s results should use more of the available range (most of these results came out either .01 or .97, with nothing in between). However, once these are taken care of, the time factor of evaluating hundreds of your students’ speaking tests could be reduced greatly.
We were then given a chance to try the system ourselves. There were some technical difficulties because of the university’s network/firewall/gremlins. We were able to record our voices using the system, but we were not able to upload the files for a machine evaluation.
Interesting work, Brian! Keep us posted.
