Think of the use of SE as having your students buy an "online speaking workbook." Your students and your supervisor would readily understand this. Don't mention "purchasing software" because it's not like that at all. The software is not for sale. We run the software on our server, and you and your students subscribe to a service that the software provides.


  • If an institution or an instructor/researcher wants to pay for SE usage on behalf of instructors and students, please contact us here for special pricing.


  • CD/DVD backup of your students' audio submissions: $20 + postage ($15 for download)
  • CD/DVD backup of your folders: $20 + postage
