Audio Script Writing
Audio Script Writing
Reference for writing that will be heard, not read. The eye can re-scan a sentence; the ear gets one pass.
The one rule: writing for the ear is single-pass
Listeners process roughly 150–160 words per minute for narration, 130–145 wpm for voice-UI prompts, and 110–125 wpm for IVR. They lose comprehension on:
- Subordinate clauses stacked more than one deep
- Parentheticals (the ear has no parens)
- Lists longer than three items without explicit numbering
- Numbers and proper nouns delivered without a beat of silence after
Core concept 1 — The one-idea-per-sentence rule
Eye version (fine on the page):
The migration, which we’d been planning since February, finally launched on Tuesday after a final round of testing that revealed two minor bugs we patched overnight.
Ear version:
We’d been planning the migration since February. It finally launched on Tuesday. The last round of testing turned up two small bugs. We patched them overnight.
Core concept 2 — Signposting
Signpost vocabulary:
- First / second / third / finally — explicit numbering
- Here’s the thing — flag a key insight
- Two reasons — set up a numbered list
- Coming up — preview before an ad break
- Back to the story — return marker after a digression
Core concept 3 — No parentheticals, no em-dashed asides
- Before: “The team (which had only formed in January) shipped on time.”
- After: “The team shipped on time. They’d only formed in January.”
Core concept 4 — Pacing markers as breath beats
| Mark | Pause length | Function |
|---|---|---|
| Comma | ~100 ms | mid-sentence beat |
| Period | ~250 ms | sentence boundary |
| Em-dash or ellipsis | ~350–500 ms | dramatic pause |
| Paragraph break | ~750 ms–1.5 s | scene change |
[pause] stage direction |
author-specified | deliberate silence |
Core concept 5 — The cold open
Three patterns that work:
Pattern A — Drop into a scene:
It’s 2 a.m. The paging system goes off. Marcus rolls over, reads the alert, and the alert is wrong.
Pattern B — A question with stakes:
What would you do if your entire backup tier disappeared in the middle of a restore?
Pattern C — A single startling fact:
Last year, 47% of incident retrospectives never produced a single action item.
Anti-pattern — The throat-clear:
Hi everyone, welcome to the podcast. Today we’re going to be talking about…
Core concept 7 — Voice-UI prompts (Alexa, Google Assistant, Siri)
Three constraints beyond “writing for the ear”:
- The prompt must end with an explicit prompt-for-input.
- Confirm without echoing. “Adding milk to your list” is good; “I heard you say milk; I will now add milk to your list” is voice-UI throat-clearing.
- Three-option ceiling. Lists of more than three options exceed working memory.
Core concept 8 — IVR scripts
- Most-likely path first. Order by call-volume share, not alphabetical.
- Always offer a human escape. “Press 0 at any time to reach an agent.”
- Confirm critical inputs. Read back at the cadence a person can write down.
- Re-prompt twice, then escalate. Caller silence twice in a row = route to agent.
Core concept 10 — Podcast show notes craft
Required sections:
- Episode title — keep under 60 characters; concrete, specific
- One-paragraph summary — 50–80 words; uses the episode keyword once
- Chapter timestamps — 4–8 chapters;
[12:15] How to find your first sponsor - Guest bio — 1 paragraph, links to guest sites
- Mentioned resources — every link spoken aloud
- Transcript — full or summary
- Call to action
Anti-patterns
| Anti-pattern | Why it fails | Fix |
|---|---|---|
| Long sentences with nested clauses | Ear loses the through-line | One idea per sentence |
| Em-dashes and parens in spoken prose | No audio equivalent | Hard sentence break |
| Throat-clear intros | Loses 20–30% in 60s | Cold open first |
| Voice-UI prompt without input request | Caller doesn’t know it’s their turn | End with explicit prompt |
| IVR with no zero-out | Caller rage | Always offer human escape |
| Generic show-note chapter labels | No SEO, no scannability | Concrete labels with keywords |
