There are several different types of stuttering, and the type a person experiences can vary depending on their individual circumstances and the severity of their condition. Some common types of stuttering include:

Repetitions: This type of stuttering involves repeating a sound, syllable, or word, either voluntarily or involuntarily. For example, a person may repeat the first sound of a word, such as "c-c-c-cat," or repeat a whole word, such as "I-I-I want to go."

Prolongations: This type of stuttering involves prolonging a sound, syllable, or word, either voluntarily or involuntarily. For example, a person may prolong the first sound of a word, such as "sssssssugar," or prolong a whole word, such as "Iiiiiiii want to go."

Blocks: This type of stuttering involves an involuntary pause or stoppage in speech. The person may be unable to produce any sound at all, or may struggle to get the word out. This can cause them to repeat or prolong sounds in an effort to continue speaking.

Interjections: This type of stuttering involves inserting a sound, syllable, or word into the middle of a word or sentence. For example, a person may say "I-I want to go to the-the store."

Secondary behaviors: This type of stuttering involves physical or verbal behaviors that a person may use to try to speak more fluently. These behaviors may include facial grimacing, eye blinking, or using fillers such as "um" or "ah."

It is important to note that not all people who stutter experience all of these types of stuttering, and the specific types a person experiences can vary over time. A speech-language therapist can help identify the specific types of stuttering a person is experiencing and develop a treatment plan to address them.
