Did you know that speaking more loudly does not automatically make an explanation easier to understand? Picture two students presenting a Science experiment. One calls out every word at the same loudness and rushes through the results. The other speaks at a comfortable level, pauses before the conclusion and stresses the word because. The second explanation may be easier to follow even if it is quieter.
Vocabulary matters here because pace describes speaking speed, a pause creates a brief silence, volume describes how loud or quiet the voice sounds, and emphasis marks the words that deserve special attention. Knowing these four terms gives a learner four different ways to fix a presentation. ‘Speak better’ is vague; ‘slow down at the evidence and pause before the conclusion’ is something a student can actually practise.
A tiny class experiment: same words, two different meanings
Try this fictional Primary 5 classroom sentence: ‘We tested three pots, but only one plant grew.’ Say it first with the same speed and loudness from beginning to end. Now say, ‘We tested three pots | but only one plant grew.’ The vertical bar represents a small pause for practice. Readers of the report need to hear the contrast: three were tested, one grew. The numbers have not changed. The spoken organisation has.
Now move the stress: ‘We tested three pots.’ This highlights that the pots were investigated rather than merely observed. Or stress ‘only one‘ to highlight the result. A learner choosing an emphasis word is making a meaning decision, not performing a decorative trick. This is why oral English connects to reading comprehension and Science explanation: one well-placed contrast can reveal the relationship between two pieces of evidence.
Pace: the speed of the whole explanation
A brisk pace means relatively fast speech; a measured pace is deliberate and controlled. Neither is automatically correct. The listener’s task and the complexity of the information matter. ‘Our group investigated rainfall’ is usually easy to follow quickly. ‘We compared daily rainfall measured at different times with the number of waterlogged planters’ contains multiple relationships and benefits from a slower pace around the comparison.
A learner might wrongly think that a higher word count per minute always signals confidence. It may instead hide the units, the comparison or the answer. When practising, choose one difficult sentence, record it and ask an unfamiliar listener to repeat its central claim. If the listener remembers the topic but cannot repeat the claim, changing the pace around the important idea may help. A single rehearsal is not a universal speech-speed test; use it as feedback.
Pause: where silence gives structure
A pause is not the same as losing one’s place. An intentional pause separates ideas or gives listeners time to process a number. Compare: ‘The first mixture turned blue the second stayed colourless the third became cloudy.’ With pauses it becomes ‘The first mixture turned blue. | The second stayed colourless. | The third became cloudy.’ Listeners can now keep track of three observations.
Punctuation can suggest likely pauses, but speaking is not a mechanical reading of commas and full stops. Someone can pause after a contrast, before an important result or while showing a graph. The useful collocations are pause briefly, pause for emphasis and leave time for a response. A dramatic pause during a factual explanation may distract instead of clarify; restraint is another speaking skill.
Volume and projection: being audible is not shouting
Volume concerns loudness. Projection is speaking so the intended listeners can hear clearly without unnecessary strain; it is not simply shouting. A small discussion around a table and a noisy school hall require different choices. ‘Increase the volume slightly’ is an actionable request; ‘scream the important bit’ is not a good rehearsal instruction.
A microphone can change the situation. In a recording, a voice can be too quiet because the microphone is far away; raising voice volume is not the same action as adjusting input gain. The more specific the diagnosis, the less likely a group is to waste time repeating the wrong fix. A student can test audibility by playing the recording at a normal listening setting and asking a partner what is difficult to hear. Never judge a classmate’s ability or accent from one recording.
Emphasis: guide the listener to the idea that matters
The noun emphasis and verb emphasise form a useful word family. The adjective emphatic means strongly expressed. Common pairings include place emphasis on evidence, emphasise the difference and emphatic denial. The grammar matters: say ’emphasise the conclusion’, not ‘do an emphasis the conclusion’.
Here is a Secondary 1 Mathematics example: ‘We multiplied by three because the number of groups increased; we did not add three.’ Emphasising the operation helps listeners distinguish multiplication from addition. With English literary analysis, ‘The character pretended to agree’ highlights a distinction between speech and intention. In each case the emphasized word must reflect what the evidence justifies; vocal drama cannot rescue a false claim.
A five-minute rehearsal that checks understanding
- Minute 1 — mark the meaning: Underline the one sentence that answers the audience’s question. Circle a contrast or causal word, such as however or because.
- Minute 2 — read once: Speak normally and record a short passage. Do not change every delivery feature at once.
- Minute 3 — diagnose: Ask a listener two questions: What was the main conclusion? Which evidence supported it? Note the part that was unclear.
- Minute 4 — change one variable: Alter only pace, pause, volume or emphasis in the difficult section. Record the passage again.
- Minute 5 — transfer: Explain a different idea without reading the original script. See whether the same adjustment still helps.
This is an illustrative practice routine, not an official PSLE or Singapore-Cambridge examination scoring formula. Teachers should use the task’s actual criteria and their school’s guidance. For PSLE English oral practice, the student still needs to read and speak meaningfully, listen to the question and respond with relevant ideas. For Secondary 1 to Secondary 4 classes studying at G1, G2 or G3 subject levels, the same precise vocabulary can help students describe a rehearsal problem, regardless of the particular task.
Three diagnostic questions to ask before saying ‘Speak louder’
First, can the audience hear the words? If not, inspect volume, room conditions or equipment. Second, can listeners separate the ideas? If not, inspect pace and pauses. Third, can listeners tell which claim is central? If not, inspect emphasis and the logical organisation of the script. A fourth question is worth asking: is the content accurate? No speaking technique can substitute for checking the underlying Mathematics, Science or English claim.
Some learners are naturally quiet, some speak rapidly, and some change speaking patterns between languages. The point of the vocabulary is not to demand one supposedly perfect accent. It is to develop choices that help a real listener understand a real message. Parents can model respectful feedback: ‘I heard the procedure, but I missed the result after the chart’ is more helpful than ‘You are bad at speaking’.
Frequently asked questions
Should children memorise a target number of words per minute?
Not as a universal rule. A comfortable speaking rate changes with the listener, topic, room and complexity of the ideas. Observe whether an unfamiliar listener can follow the meaning before chasing a speed number.
Is a pause the same as hesitation?
Not always. A pause can be intentionally used to separate ideas. Hesitation is often an unplanned delay while searching for words. Both may appear in natural speech; the practice goal is clear communication, not removing every moment of silence.
Can emphasis change the meaning of a sentence?
Yes. Compare ‘I said some results were different’ with ‘I said some results were different‘. The factual words stay the same, but the listener’s focus shifts. Choose stress deliberately and avoid suggesting conclusions stronger than the evidence.

For further practice with meaning before performance, explore eduKateSG’s What Is Vocabulary? guide. Toastmasters International’s discussion of vocal volume and contrast offers useful examples of how speech loudness affects emphasis. An effective learner eventually needs fewer instructions from an adult: they can name what went wrong, select one adjustment, test it, and explain why the listener understood better.
