A well-built speech can still fail in the delivery, and a modest one can succeed because of it. Delivery is not decoration. It is how the words reach people: through a voice they can hear, a face they can read, and a manner that makes them want to keep listening.

Four methods of delivery

Speech teachers name four methods. In manuscript delivery you read a full text word for word. Manuscript delivery suits occasions where exact wording matters, such as an official statement or a legal announcement, but it tempts the speaker to stare at the page. Memorized delivery is risky: one lost word can derail the whole speech, and recited speech tends to sound recited. Impromptu speaking happens with little or no preparation, as when someone is asked to say a few words. Extemporaneous delivery is carefully prepared and rehearsed but given from brief notes, with the exact wording chosen in the moment. It is the method most teachers recommend for most speeches, because it combines preparation with the natural sound of conversation and lets the speaker adapt to the room.

Voice

Volume should reach the back row without shouting. Rate matters: conversational speech in English often runs somewhere around 120 to 160 words per minute, and nervous speakers tend to speed up. Pitch should vary; a flat, unchanging pitch, called a monotone, signals boredom even when the speaker cares deeply. A well-placed pause gives listeners time to absorb a point, and silence before a key line draws attention to it.

Vocalized pauses are fillers such as "um," "uh" and "you know." Everyone uses some, and a few do no harm. Many in a row suggest uncertainty. The fix is usually to get comfortable with brief silence. Two related terms are often confused. Articulation is the physical crispness with which sounds are formed; mumbling is poor articulation. Pronunciation is whether a word is said in the accepted way.

Body

Eye contact tells listeners you are speaking to them. In a larger room, look at individuals in different parts of the audience for a few seconds each rather than sweeping across heads. Norms differ across cultures, so watch how your audience responds. Gestures should grow out of what you are saying, not be planned move by move. Stand balanced, and move only with purpose.

The 93 percent myth

Many speaking guides claim that only 7 percent of communication comes from words, with the rest from tone and body. The figure comes from experiments by the psychologist Albert Mehrabian in the late 1960s, in which listeners judged feelings conveyed by single words spoken in different tones, sometimes alongside photographs of faces. Mehrabian himself has said the results do not apply to communication in general. The claim that 93 percent of communication is nonverbal misreads narrow experiments about expressing feelings. Delivery matters a great deal, but no speech succeeds on tone alone.

Nerves

Fear of public speaking is among the most commonly reported fears in surveys. It is a stress response: adrenaline brings a racing heart, shaky hands and a dry mouth. Cicero, the greatest orator of Rome, wrote in his dialogue On the Orator of a speaker who turned pale and trembled at the start of every speech, and admitted elsewhere to the same.

Several strategies help. Thorough preparation removes a large share of the fear. Focusing on the message and the listeners, rather than on how you look, turns attention outward. Slow breathing before you begin calms the body. Some research suggests that reframing the arousal as excitement, telling yourself that you feel excited instead of trying to calm down, can improve performance, since the two states feel similar in the body. And speakers usually overestimate how visible their nerves are; the audience sees far less than you feel.

Rehearsal

Reading your notes silently is not rehearsal. Rehearse aloud, on your feet, and timed, ideally in front of a friend or a recording device. Practice the opening and closing most.

Worked example: a cross of gold

In July 1896 the Democratic National Convention met in Chicago, divided over whether the United States should back its currency with gold alone or with silver too. William Jennings Bryan, a thirty-six-year-old former congressman from Nebraska, was not a leading candidate for the nomination.

Bryan was well prepared. He had tested and polished some of his best lines in earlier speeches around the country, so he knew how they would land, and he delivered the speech without reading from a manuscript. Speaking in a vast hall long before microphones, he relied on a famously strong and clear voice. He closed with an image: "You shall not press down upon the brow of labor this crown of thorns, you shall not crucify mankind upon a cross of gold." By several accounts he stretched out his arms as he finished, and the hall erupted. The next day the convention nominated him for president.

The speech shows rehearsal and extemporaneous-style delivery at work, along with a limit worth noting. Delivery won the room, but Bryan lost the general election that November. Delivery carries an argument to listeners; it cannot replace the argument.
