Here are some example of Sound prolongation, the 3rd type of stuttering.
Let's listen as Christy prolongs the vowel in the word "sometime"
Child: Then "so-o-o-o-metimes" I stumble over words.
Finally, let's see Justin prolong the "e" in the word "we"
Child: It was like "we-e-e-e-e" were driving to farm fields.
