ISLE: download the ISLE Demonstrator

This demonstration package shows the basic features of the ISLE software: recognition of accented learner speech, localization of potential areas, and diagnosis of those errors at a very specific level. Although the methods used in the ISLE demonstrator are theoretically applicable to any language pairs, only German and Italian learners of English are targeted by this software.
