Overview
A demo reel is your primary marketing tool as a voice over artist — the first thing a client, agent, or casting director hears when considering hiring you. It's a short audio montage that showcases your range, technique, and the kinds of work you're right for. A great demo gets you work. A poor one — wrong structure, bad audio quality, wrong scripts — actively damages your chances. This guide covers what makes a demo work, how to produce one, and where to put it once it's done.
What You Need
- A quality home recording setup (see How to Record Voice Over at Home)
- 3–6 short scripts in your target style (see Step 3 for what to write)
- A DAW for editing (Reaper, Audacity, Logic, or Audition)
- Optional: royalty-free music beds for the commercial demo
Steps
What a demo reel is and who it's for
A demo reel is not a performance showcase — it's a marketing tool designed to answer one question from a client: "Can this person do what I need?" It should sound like real work. Not "here is a person showing off their voice," but "here is a real ad, a real narration, a real character." Clients and agents listen to demos while doing other things. They make a decision in the first 10 seconds. If the first excerpt doesn't sound like professional, broadcast-ready work, they're gone. The demo needs to match the production quality — and the performance quality — of what the client is paying for.
Types of demo reels
You need a separate demo for each major VO category you work in. Commercial demo: 60–90 seconds, 4–6 excerpts showing range across tone and energy. The most important demo for most new VO artists. Corporate/narration demo: 60–90 seconds, 3–4 excerpts of e-learning, documentary, and corporate training reads — conversational, authoritative, educational. Audiobook demo: 2–3 minutes, showing your character differentiation and ability to sustain tone — longer because clients need to hear you hold a consistent voice. Character/animation demo: 60–90 seconds, multiple distinct voices — requires strong character work, most specialised. Start with one demo in the category where your voice is most naturally competitive. Adding more demos later is easier than producing a weak demo in a category you're not ready for.
What goes on a commercial demo
A commercial demo should contain 4–6 excerpts of approximately 10–15 seconds each, covering different tones: warm and conversational (insurance, banking, healthcare), upbeat and energetic (consumer goods, tech, youth-facing brands), authoritative (automotive, finance, corporate), gentle and reassuring (pharmaceutical, charity, children's products), and optionally a quirky or comedic read. Write or adapt scripts that sound like real ads — not made-up brand names, but convincing, plausible scripts. Study current broadcast commercials. Your best excerpt goes first. Put the second-best last. The middle can vary. The goal: each excerpt should sound like it came from a different brand's real campaign, not like one person doing different voices.
Recording and production quality
The audio quality of your demo is a direct signal of the quality of your home studio. If the demo sounds like a bedroom — room reverb, mic noise, thin frequency response — clients assume your delivered work will too. Record in your treated space with your best microphone and interface. Use the same settings as your professional work. Process each excerpt with EQ, compression, and limiting to match broadcast levels (−16 LUFS for streaming, −9 LUFS to −12 LUFS for broadcast delivery). Add royalty-free music beds at a level that supports rather than competes with your voice — typically −18dB to −15dB under the voice. Fade music in before your voice, under your delivery, and out naturally. The voice should always be the dominant element. The overall demo file should be a single MP3 at 320kbps.
Length and structure
Total demo length: 60–90 seconds for commercial, 60–90 seconds for narration, up to 2–3 minutes for audiobook. The most common mistake is making demos too long. Clients do not listen for 3 minutes to a commercial demo. They listen for 15–20 seconds, form a judgment, and move on. Your demo should be shorter than you think. Structure: open with your single best, most representative excerpt — no intro music, no "Hi, I'm [name]." Straight into the read. Transition between excerpts with a brief natural fade (0.5–1 second) rather than hard cuts. End cleanly. A brief end slate — "[Name] — [website/contact]" — is acceptable, but keep it under 3 seconds.
Where to host and submit
Host your demo on your own website — a dedicated page with an embedded player, a download link, and your contact information. Use SoundCloud or Soundsnap for embeddable players if you don't have a website yet. Submit your demo when creating profiles on P2P platforms (Voice123, Voices.com). Include the link in every client email and agent submission. Name the file professionally: "[YourName]-Commercial-Demo.mp3" — not "demo_final_v3_FIXED.mp3." Update your demo as your skills and credits improve — typically every 1–2 years for an active talent. An outdated demo that no longer represents your current quality is worse than no demo, so refresh it when you can clearly hear the gap between the demo and your current work.
Pro Tips
- A professionally produced demo (recorded and edited by an experienced VO coach or producer) is worth the investment, especially for your first commercial demo. The difference in how it's received by agents and casting directors is measurable. Expect to pay £300–£800 for a professional production.
- Don't put real brand names in a self-produced demo unless you have actual bookings from those brands — a false impression of credits is dishonest and gets discovered quickly.
- Have 3–5 people in your target market (VO coaches, working talent, agents — not friends and family) listen to the demo and give honest feedback before you release it.
- Your demo is never finished — it's a living document. As you book real commercial work, replace self-produced excerpts with actual aired spots. Real credits are always more persuasive than produced demos.
