Sorry about the wall of text. Do you mean tips on how to alleviate stuttering? I'd say pre-voice exhalation, easy onset, light touches, linking, and cancellation. Pre-voice exhalation: before you begin to speak, let some air out for one second. Do not pause between the exhale and speaking, or the exhale was useless. The idea behind this, is that the exhale gets your vocal chords moving before you begin to speak. Your vocal cords are not tensed up, so it decreases the likelihood of stuttering. This also does away with the problem many stutterers have of holding their breath before they start speaking. Easy onset: going along with pre-voice exhalation, many stutterers begin speaking too harshly. Easy onset is particularly helpful with vowel sounds. Basically what you need to do, is pronounce the vowel sounds very softly. Using a lot of emphasis causes tension, which can cause you to block. Instead, don't pronounce the sound harshly. Say the word softly. Take, for instance, the word "Apple." Pay attention to the way your speech-related muscle groups feel when you say the word. If you're really emphasizing the A sound, you should feel it. I feel it in my diaphragm and throat. If you say it softer, you will not feel as much tension. Light touches: The same concept as with easy onset, but for consonant sounds. The problem here is tension in the lips, tongue, and jaw instead of vocal chords and diaphragm. When the articulators come together too hard, airflow stops and your voice isn't able to start effectively. To get the sounds out, you need to make the sounds gently. The lips, tongue, jaw, and teeth should barely touch each other when beginning the word. Again, do not emphasize the pronunciation, do not pronounce the sound harshly. Linking: a lot of people who stutter have very choppy speech patterns, which results in mid-sentence stutters. Keep your voice "on" throughout each sentence. The way I think of it is, instead if considering your sentence a sentence, think of your sentence as a really long word. Blend the end of each word into the start of the next. Do not take pauses, and if you do, use pre-voice exhalation again. This ensures the vocal chords continue to vibrate, preventing them from tensing, and you from stuttering. Cancellation: instead of continuing to block until you finally get the sound out, stop. When you find yourself blocking, just stop. Let your air out, breathe in, and use pre-voice exhalation. I know its really hard to catch yourself in the moment, but it's good practice to stop yourself and try again. In any case, if you want to appear confident despite the stutter, you should own the stutter when it happens. Do not let it appear to be something that bothers you. Sometimes the speech techniques won't work. It also does you no good to hide the fact that you stutter. That only creates anxiety and shame. Disclose your stutter to people, either upon introducing yourself (ex. "I have a speech disorder, just so you know. How's your day been?") or when you block (I have a speech disorder, this sound gives me trouble sometimes- and continue with your sentence.) A lot of people are not aware enough of stutters to recognize them, even when they hear them. It can come off as strange to them. Disclosing it and addressing it before it becomes the elephant in the room can do wonders for you. Not being too hard on yourself and having a sense of humor about it can be great, too. Like if you have a particularly bad block, you can chuckle and say a lighthearted, "Damn it!" or "Sorry, I'm buffering." or any kind of off-comment that makes light of it. It gives off the impression that you are comfortable enough about it to address it and make fun of yourself a little. I know not everyone gets to the point of being comfortable joking about such problems, as they are sensitive topics. If you're not comfortable with it, that's totally fine. Joking about it from time to time is just one way of owning it. The point is that the best way to appear confident, despite the stutter, is to own it. Disclose it, joke about it, continue making eye contact, whatever else.
