How to Write a Debate Speech: Structure, Template and Examples
A good debate speech has an opening that frames the question, two or three developed arguments, rebuttal of the other side, and a closing that compares. This guide gives a template with timings for a five-minute speech, a worked example, and delivery tips.

A speech is not an essay
Debate speeches are heard once, at speaking pace, usually with no ability to rewind. That changes how they should be written. Sentences should be short. Key points should be signposted. Important ideas should be repeated in a different form. An essay can hold a complex clause; a speech cannot.
Write for the ear. Read each sentence aloud as you draft it. If you run out of breath or lose the subject, split it.
The five-minute template
This structure works for most constructive speeches and can be scaled to longer or shorter times.
| Part | Time | What it does |
|---|---|---|
| Opening | 30 seconds | State the motion in your own words, your position and a roadmap: “I will make two arguments.” |
| Argument one | 1 minute 15 seconds | Signpost, claim, reason, evidence, impact. |
| Argument two | 1 minute 15 seconds | Same structure. |
| Rebuttal | 1 minute | Answer the other side’s best point; say why it does not change the outcome. |
| Conclusion | 30 seconds | Compare: what decided the debate, and why your side is ahead. |
The opening: frame, position, roadmap
The first thirty seconds set the agenda. Say what the debate is about, where you stand and how many points you will make. For example: “Today’s debate is about whether schools should ban phones. We say yes, and we will show you two things: phones damage learning, and a ban is fairer than the alternatives.”
Avoid starting with a dictionary definition, a famous quotation or an apology. They use up your best seconds. Start with the question.
Building each argument
Use the same four-part structure every time so the audience learns to follow you.
- Signpost: “My first argument is about learning.”
- Claim: “Phones reduce attention in lessons.”
- Reason and evidence: explain why and give one specific example or study.
- Impact: “That matters because attention lost in class is hard to recover.”
A worked example
Here is one argument written for the ear. “My first argument is about learning. Phones reduce attention in lessons. When a phone is in a pocket, a student has to resist checking it. When it is on a desk, even a silent screen draws the eye. Research on classroom device use has found lower attention and test scores when phones are present, though the size of the effect varies. That matters because attention lost in one lesson is rarely recovered, and it falls hardest on students who already find school difficult.”
Notice the short sentences, the claim at the start, the mechanism in the middle and the stated impact at the end. It also admits that the effect varies, which makes the speaker more credible, not less.
Rebuttal inside a constructive speech
Even a first speech benefits from answering the other side’s best argument. If you are speaking second, rebuttal comes first or second in your speech. Use the pattern “They say, but, because, so.” They say a ban removes useful tools; but exemptions can cover accessibility; because the ban targets entertainment use; so the benefit is kept and the harm is not.
The conclusion: compare, do not repeat
A conclusion that lists your arguments again adds nothing. Instead, name the one or two issues that decide the debate and say why you are ahead. “The question in this debate is whether a flexible policy can protect attention. Our answer is that it cannot, because enforcement is left to teachers who already have too much to do. A clear rule can.”
Delivery tips that matter most
Delivery determines how much of your speech lands.
- Pace: speak slower than feels natural; pause after key points.
- Eye contact: look at the judges or audience for a full sentence at a time.
- Notes: headings only; do not read.
- Voice: lower your pitch on the last word of a sentence to sound sure.
- Signposting: say “first”, “second”, “finally”. Repetition helps listeners follow.

Speeches for different roles
The template shifts a little depending on where you speak. A first speaker defines the motion, presents the model and gives the first two arguments. A second speaker spends the first half rebutting the opposing first speaker and the second half presenting new arguments. A closing or summary speaker stops adding new points and instead weighs the debate: which side won on which issue, and why. If you are asked to give a reply speech, as in World Schools, write it on the spot from your notes of the round. It should be a story of the debate in three or four sentences, not a recap of your case.
Common mistakes
These errors are common in beginner speeches.
- Too many points. Two or three are enough.
- No signposts. Listeners cannot find the structure.
- Reading a script. It sounds flat and breaks eye contact.
- Overrunning. Judges stop listening when time is up.
- Dismissing the other side. Take their best point seriously and answer it.
Frequently asked questions
How do you start a debate speech?
Start by stating the motion in your own words, your position and a roadmap of your points. Avoid dictionary definitions and apologies.
How long should a debate speech be?
It depends on the format. Four minutes is common in public forum, six to eight minutes in Lincoln–Douglas, policy and World Schools, and seven in British Parliamentary. Rebuttals are usually two to five minutes.
How many arguments should be in a debate speech?
Two or three. More than three and each one tends to be too thin to persuade.
How do you end a debate speech?
End with a comparison. Name the issues that decided the debate and say why your side is ahead. Do not repeat your points or introduce a new one.
Should I write out my debate speech word for word?
It is better to write headings and a few key lines, then speak from them. A fully written speech tends to sound flat and cannot adapt to what the other side says.
