I think it depends on what she means by eliminate. Stuttering can be eliminated bhmy managing it (if it's mild mostly) but it takes a lot of effort. You have to change the way that you speak, and it often involves slowing down your rate of speech and other aspects of how you talk. I wouldn't call it a "cure" though, since cure implies something that you take and you don't evet have to think about the problem again. Speech therapy (for some people) can eliminate stuttering in the same way that physical therapy can make some people who werr in accidents walk again (with a lot of effort over a period of time). Also, it would take some drastic changes probably.
