Voice Acting Techniques: Character Voices, Copy and Mic Technique

In voice work, the microphone hears everything: a smile, a frown, a moment of doubt, a lazy consonant. There is no face or body to help sell a performance, so every choice has to live in the sound. That is what makes voice acting so demanding, and so satisfying when it works.

This guide covers the core techniques voice actors use, from reading copy and creating characters to mic technique and looking after your voice. It works for commercials, animation, games, narration and audiobooks alike.

Act first, voice second

The most common mistake new voice actors make is “putting on a voice” and forgetting to act. Before you think about how something should sound, answer the same questions you would for any scene:

• Who am I? Age, background, personality, status.
• Who am I talking to? One person, a friend, a child, a customer, an enemy.
• What do I want? To reassure, persuade, warn, seduce, sell, explain.
• Where am I? A quiet room, a battlefield, a busy kitchen. Space affects volume and energy.
• What just happened? The moment before shapes the first line.

When you know the answers, the voice follows. A sound that comes from a clear intention will always be more convincing than a clever voice with nothing behind it.

Make copy sound conversational

Commercial and narration scripts are written to be read, but they need to sound spoken. Techniques that help:

• Talk to one person. Picture someone specific, a friend or the ideal listener, and speak to them. “Hey, you” energy beats “Hello, everyone.”
• Find the operative words. In each sentence, decide which one or two words carry the meaning, and let the rest support them. Don’t stress everything.
• Break up the rhythm. Real speech has small hesitations, pace changes and natural emphasis. Avoid the “announcer” sing-song.
• Smile when it fits. You can hear a smile. Equally, you can hear tension or boredom.
• Know the brand or story. Understanding who you are speaking for, whether it’s a bank, a skate brand or a fantasy world, tells you how to pitch it.

Create character voices that hold up

For animation and games, you will often need distinct character voices, sometimes several in one session. Build them with intention:

1. Start from the character, not the sound. What is their personality and attitude? A nervous character might speak fast and high; a confident one might slow down and drop lower.
2. Use placement. Moving the sound around (nasal, throat, chest, head, mask of the face) changes the colour of your voice quickly and safely.
3. Change the physicality. Posture, facial expression and gesture change your sound. Hunch, puff up, grin, scowl. Animation actors move a lot in the booth for a reason.
4. Adjust pace, pitch and rhythm. Small changes go a long way. Give each character its own rhythm of speech.
5. Add a quirk carefully. A lisp, a laugh or a catchphrase can help, but it should come from the character and be sustainable.
6. Record a reference. Keep a short clip of each character so you can match it in later sessions, sometimes months later.

Above all, the voice must be repeatable and safe. If it hurts to do for one minute, you can’t do it for four hours.

Mic technique

The microphone is your scene partner, and it is very sensitive. Basic technique:

• Find your distance. Typically around a hand’s width from the mic, but it varies with the mic and the style. Move closer for intimate reads, back off for louder moments.
• Work slightly off-axis to reduce plosives (pops on P and B sounds), and use a pop filter.
• Stay consistent. Moving around changes the tone and volume. Keep your head steady relative to the mic, even while your body is engaged.
• Manage loud sounds. For shouts and screams, turn your head or step back so you don’t distort the recording.
• Control mouth noise. Stay hydrated, avoid dairy and sugary drinks before sessions and keep apple slices or water nearby. Many voice actors swear by green apples.

Breath and stamina

Long reads, especially audiobooks and narration, need good breath support. Breathe low into the belly and ribs, plan breaths at natural pauses and avoid gasping before lines. In editing, breaths are often reduced but rarely removed completely, because silence between lines sounds unnatural.

For audiobooks, pace yourself through the day. Your voice at hour six should match hour one.

Taking direction

Voice directors and clients often give quick, short notes: “warmer,” “less salesy,” “faster,” “more of a smile,” “go again but bigger.” The skill is to make a clear change each time while keeping what was working. Good voice actors:

• Offer a few different reads without being asked
• Make clear adjustments rather than tiny ones
• Stay relaxed and open, even with vague notes
• Don’t argue, but ask a clarifying question if needed

Look after your voice

Your voice is your instrument and your income. Protect it:

• Warm up before every session. See our vocal warm-up routine.
• Drink water throughout the day.
• Avoid shouting, whispering for long periods and clearing your throat repeatedly.
• Rest your voice after heavy sessions, especially screaming or creature work.
• Get enough sleep and avoid smoking.
• See a voice specialist if you notice persistent hoarseness or pain.

Practise every day

• Read aloud daily from different sources: news, ads, novels, game scripts.
• Record and listen back critically.
• Imitate voices you hear around you, then make them your own.
• Practise cold reading to get quicker at making choices.
• Keep a file of copy you like, and reread it in different styles.
