What will work also depends on what kind of stutter you have. I found out that technically I don't have a stutter in the typical way, but cluttering. My treatment is more a consciousness of what brings on the stutter (getting a bit too excited about something, talking too fast, being unprepared and trying to fumble through an idea.) If you can talk to a therapist or a specialist, I highly recommend it. I was lucky enough to see one when I was in 8th grade when a teacher spoke up for me.
