There's 3 different core behaviours of stuttering: repetitions, blocking, and prolongation. OP exhibits prolongation. Instead of repeating sounds, or not being able to get sounds out, OP prolongs the sounds. OP, I'd suggest the Pre-voice Exhalation, Easy Onset, and Continuous Phonotation techniques. Pre-voice Exhalation: exhale for about one second before you start to speak. Exhalation opens up the vocal chords, instead of "trapping" air under them. Easy Onset: particularky helpful with vowel sounds. When you begin speaking, your vocal chords might come together too hard and lock up. Instead of speaking with a hard onset, start your voice off softly. Do not place emphasis on the word. If you're saying the word, "Eventually," if you were to stutter you may feel tense in your vocal chords. Instead of emphasizing the sound, let it just slip out. Make the sound gentle, instead of harsh. Continuous Phonotation: this operates on the same principle as Pre-voice Exhalation- keep the vocal chords open and do not allow them to close. The best way I can describe this technique is to think of sentences as one long word instead of individual words. Link your words together. Let the end of one word flow into the beginning of the next. If you need to pause to breathe or think of how your sentence will continue, use pre-voice exhalation once more. This keeps your vocal chords open, reducing opportunity for them to lock up to cause you to stutter.
