Can tongue twisters help with stuttering?

Can tongue twisters help with stuttering? I noticed that I usually stutter with words that start with T or S. So for example, saying "statistics" while talking to my friends or in public causes me to stutter. I've been trying to practice tongue twisters recently and I've found that it helps a little. I would like to ask if practicing tounge twisters really help or is this a placebo effect?
