<human>: I've heard that there are a number of different types of stutters. What are the most common types?
<bot>: The most common types of stutters are phonological, motoric, and mixed. Phonological stuttering is caused by problems with the way a person’s brain processes language. Motoric stuttering is caused by a problem with the way a person’s body moves when they speak. Mixed stuttering is caused by both problems in the brain and the body.
