Great voiceovers start long before generation—they start on the page. When your script is structured for synthetic voices, you get clearer diction, smoother pacing, and far fewer retakes. This guide shares practical, field‑tested techniques used by teams producing product demos, courses, explainers, and multilingual marketing at scale.
1) One Idea per Sentence
Short sentences improve rhythm and intelligibility. Aim for 12–20 words. Split compound thoughts with a period or em dash. If the voice sounds rushed, reduce clauses rather than only slowing speed.
2) Punctuation Controls Pauses
Commas create micro‑pauses; periods create full stops. Use colons before explanations, and dashes to signal emphasis or asides. Avoid ellipses for long pauses—prefer a sentence break.
3) Explicit Emphasis
Write emphasis into the sentence structure. Move key words near the end. Prefer active voice. Replace filler with concrete verbs. If a word must “pop,” consider a brief sentence of its own.
4) Numbers and Units
Spell out round numbers and use consistent unit spacing. Example: “ten thousand users,” “44.1 kHz,” “−16 LUFS.” For currencies, write the symbol once per value and keep locale formatting consistent.
5) Acronyms and Brands
Disambiguate acronyms you want spelled out: write “U.S.” or “U‑S,” not “us.” For brand names with unusual pronunciation, add a hint during drafts, then remove once stable.
6) Natural Connectors
Prefer conversational connectors—“so,” “now,” “next,” “here’s why.” They help the model choose natural intonation and reduce monotony across sections.
7) Structure for Previews
Break long scripts into blocks of 2–5 sentences. Generate and review one block at a time. Use headings to signal topic changes for consistent energy across sections.
8) Multilingual Considerations
Translate natively, not literally. Reorder sentences to match target language rhythm. Replace culture‑specific references with local equivalents. Choose voices that fit market expectations.
9) CTA That Converts
Keep calls‑to‑action short and directive. One verb, one benefit, one next step. Add a localized CTA per language for higher conversion.
10) Timing and Breath
If lines feel breathless, add commas after introductory phrases, split coordination, or insert a short sentence. Avoid chaining three clauses without punctuation.
11) Read Aloud Test
Read your script out loud. Awkward phrasing becomes obvious. If you stumble, the model likely will too. Rewrite until you can read it smoothly at your target pace.
12) Style Consistency
Decide on tense, person, and tone—then stick to it. Maintain consistent terminology across sections and languages. Keep brand terms identical; translate descriptive words.
