How to Create a Voice Over Demo at Home (Beginner Guide)

I'm often asked what you need to get started in the VO business.

Once upon a time, in the deep dark past, I set about creating my first voice acting demo. This was 2003, 4 years before the first iphone and a year before Garageband made home audio recording accessible to everyone. Back then, I did it with a sound engineer at radio station who recorded, mixed and strung together a few short grabs (one of which featured me playing a poodle in a dog snack commercial) and I was on my way. I used that demo for the first 10 years of my career. Today, you don't need that soud engineer or that radio station, you can make a really high quiality demo to kick off your VO career at home. The moral of my story though? Start off with quality.

In this article I’m going to talk about about how to record a commercial voiceover demo from a home studio. What to buy, what to record, and what to record it on.

Disclaimer: this isn’t about cutting corners so you can avoid hiring professionals forever. A strong demo is your shop window, and there’s a reason many working voice actors eventually invest in professionally produced reels. But if you’re starting out—or updating your sound—this will get you something clean, credible, and competitive.

First: your “studio” is as important as your microphone

Before you spend a penny on shiny equipment, you need to get one thing straight: bad audio is usually a room problem, not a gear problem. Echo, reverb, outside noise—these are what make a recording sound amateur. You can have the best microphone in the world and still sound like you’re announcing from a tiled bathroom.

What you’re aiming for is a dead space. Soft furnishings are your friend. Think:

• Wardrobes full of clothes

• Thick curtains

• Rugs and carpets

• Duvets (yes, really)

Many voice actors start by recording in a closet or building a makeshift booth with blankets. It’s not glamorous, but it works. The goal is to absorb sound, not reflect it. If you take nothing else from this article: fix your space before you upgrade your kit.

What equipment you actually need (and what you don’t)

This is the point where people either overspend or underspend. You do not need a £2,000 microphone. But you also probably shouldn’t be recording your demo through a gaming headset.

A simple, reliable setup looks like this:

Microphone- A large diaphragm condenser mic is the industry standard for commercial voiceover. Models like the Audio-Technica AT2020 or Rode NT1-A are popular because they sound clean without being overly expensive.

Audio Interface- This is the box that connects your mic to your computer and handles sound conversion. Something like the Focusrite Scarlett 2i2 is a solid, widely used option.

Headphones- Closed-back headphones let you hear details without sound leaking into the mic. You don’t need anything exotic—just accurate.

Mic stand and pop filter - A stand keeps your mic stable. A pop filter stops explosive “p” and “b” sounds from ruining your take. Both are inexpensive and non-negotiable.

That’s it. Notice what’s missing: mixers, fancy racks, glowing equipment that looks like it belongs in a spaceship. You don’t need them to record a strong demo.

What software to use (without losing your mind)

Recording software—often called a DAW (Digital Audio Workstation)—can look intimidating, but for voiceover you only need a fraction of what it offers.

Three solid options:

• Audacity (free, simple, does the job)

• Garageband (as above)

• Adobe Audition (paid, industry standard, very capable)

• Reaper (affordable, powerful, slightly steeper learning curve)

At a basic level, you’re doing three things:

1. Recording clean audio

2. Cutting mistakes and tightening timing

3. Applying light processing (EQ, compression, maybe a touch of normalization)

If you find yourself adding dramatic effects, you’ve probably gone too far. Commercial demos should sound polished, not produced within an inch of their life.

What kind of material to record: Be YOU first

This is where many demos fall apart—not because of sound quality, but because of content.

A commercial demo isn’t one long read. It’s a series of short clips (usually 5–8 seconds each) that showcase range, tone, and style. Overall, when you're choosing material, think about your natural tone as a person. VO is for the most part about selling. Selling a product or an idea. Think about what kinds of situations in real life that you would be the most effective salesperson for, then lean towards this material. Trust me, your personality DOES shine through your voice. It's the reason why synthetic voices will never be a proper substitute for humans.

You want variety. Think:

• Upbeat retail (the “big sale this weekend” energy)

• Warm, conversational brand reads

• Dry, informative corporate tone

• Playful or comedic spots

• Calm, reassuring delivery (think healthcare or finance)

Avoid copying scripts directly from existing ads. Aside from legal issues, casting directors have heard those reads a thousand times. Instead, write original scripts in the style of real commercials.

A simple structure:

• 6–10 clips total

• Each clip 1–2 sentences

• Total demo length: 60–90 seconds

And most importantly: start strong. The first 10 seconds determine whether anyone listens to the rest.

How to actually record it

Once your space, gear, and scripts are sorted, the recording process is straightforward—but the details matter.

• Mic position: about 6–8 inches from your mouth, slightly off-axis to reduce plosives

• Consistent levels: aim for strong signal without clipping (peaking around -6 dB is a safe target)

• Multiple takes: don’t settle for the first decent read—give yourself options

• Stay physically engaged: standing often improves energy and delivery

  
  

Record each script separately so you can pick the best takes later. Trying to nail everything in one continuous session is a fast track to frustration.

Editing: where good becomes professional

Editing is where your demo starts to feel like a demo, rather than a collection of recordings.

You’ll want to:

• Remove breaths that are distracting (not all of them—just the heavy ones)

• Tighten pacing between lines

• Balance volume across clips

• Apply light EQ (to clean up muddiness)

• Use gentle compression (to even out dynamics)

You can also add background music—but tread carefully. Music should support your voice, not compete with it. Keep it subtle, low and appropriate to each clip. A common mistake is overproduction. If your demo sounds like a film trailer when you’re aiming for a natural commercial read, something’s gone wrong.

Putting it all together

Once your clips are edited, arrange them into a single track. Think about flow:

• Open with your strongest, most marketable read

• Alternate styles to keep it interesting

• End on something memorable

Listen through from start to finish—not as the performer, but as someone hearing you for the first time. Does it feel engaging? Does it drag? Does anything sound out of place?

If possible, get feedback. Other voice actors, coaches, or even brutally honest friends can catch things you’ve become deaf to.

Final thought: good enough is better than perfect

There’s a point in this process where improving your demo further becomes less about quality and more about avoidance. Your first home-recorded demo won’t be flawless. It doesn’t need to be. It needs to be clear, versatile, and representative of what you can actually deliver. Because ultimately, that’s what clients care about: not your microphone, not your software, but whether you can sound like the voice they’re hearing in their head.
