Volume, projection and being heard

The quiet speaker who is told to be louder generally responds by straining the throat, which is unsustainable and does not carry.

Projection versus volume

The distinction that matters.

Shouting increases loudness at the source through effort at the larynx, which is tiring, damaging over time, and produces a sound that does not travel well.

Projection uses breath support and resonance to produce a sound that carries, at moderate effort.

Which is why trained speakers can fill a room without apparent strain and untrained ones cannot fill it while straining.

And it means the fix is technique rather than effort.

Breath support

The foundation.

Breathing low, with expansion at the base of the ribs and the abdomen rather than the shoulders.

A steady controlled exhale rather than a rush at the start of the phrase.

Enough breath taken before the phrase, which requires planning where the breaths go.

Which is why long unbroken sentences are the enemy of projection: the speaker runs out and the volume collapses at the end.

And why phrasing a script for breath is part of the vocal technique rather than a separate task.

Resonance

Where the carrying power comes from.

The sound is amplified in the spaces of the throat, mouth and nose, and the shape of those spaces determines how much.

Which means a dropped jaw, a released tongue and an open throat produce more sound for the same effort.

Humming exercises train the sensation of forward resonance, which is what carries.

And tension anywhere in that chain — a clenched jaw, a raised larynx, tight shoulders — reduces it directly.

Practical technique

What to actually do.

Stand with weight balanced and the spine long.

Release the jaw deliberately before speaking.

Aim the voice at the back of the room, which changes the production without conscious effort.

Open the mouth more than feels natural, which is the single most common deficiency.

Slow down, since fast speech is harder to hear at distance.

And over-articulate consonants, which is what makes speech intelligible across a room more than volume does.

The room

Which changes everything.

Hard reverberant spaces smear sound, so speak more slowly and pause more, since volume makes it worse rather than better.

Soft rooms absorb, so more energy is needed.

Outdoors, sound disappears, and the audience must be close.

Long narrow rooms are harder than square ones.

And the practical step is to arrive early, stand where you will speak, and have someone at the back tell you whether they can hear.

Microphones

Which change the task entirely.

With a microphone, projection is unnecessary and often counterproductive.

Speak at conversational volume, closer to the microphone, with the energy going into variety rather than loudness.

Keep a consistent distance.

Test it before the audience arrives.

And do not tap it, which damages equipment and tells you nothing.

The quiet speaker

Where the cause is often not vocal.

Habitual quietness is frequently about not wanting to take up space rather than about vocal capability.

Which means the technique alone will not change it, since the speaker will revert under social pressure.

What helps: practising at a volume that feels excessive, in private, until it stops feeling excessive; recording, since the perception of one's own volume is unreliable; and being given explicit permission to be loud, which sounds trivial and is frequently the actual obstacle.

The over-loud speaker

The other end.

Consistently speaking louder than the situation requires is tiring for listeners and reads as domineering.

Causes include hearing loss, which is worth checking, and habit from a loud environment.

What helps: recording, feedback from someone trusted, and deliberately matching the volume of the room.

And varying it, since constant volume at any level is the actual problem.

Sustaining it

Over a long day.

Amplification wherever it is available, which is not an admission of weakness.

Breaks, and quiet during them rather than social talk in a noisy room.

Hydration through the day.

Avoiding throat clearing, which is damaging and self-perpetuating.

And stopping if it hurts, since pain on speaking is a signal rather than an inconvenience.
