Pronunciation – If your speech isn’t clear, it could be that your jaw is too tense. Practice saying “va va va va in different pitches to open your jaw.
Power – Your vocal cords depend on the air coming up from your lungs. Keep your posture relaxed and try to breathe from the abdomen, not the chest. A jutting chin keeps the larynx high, making yur voice breathy.
Projection – To make your voice louder, practice the popular playground taunt “nyeh-nyeh nyeh nyeh-nyhe.” This raise your tongue and opens spaces in the vocal tract that carry extra sound- think how load a baby can cry.
Pace – Worrying that you’re not keeping your listeners interested can make you speak too quickly. Learn to recognize this and relax.
