Prompts and scripts for AI avatar and talking-head video

A script written for synthetic delivery

Write a [MINUTES]-minute presenter script about [TOPIC] for [AUDIENCE], to be delivered by an AI avatar.

Constraints:
- Maximum 18 words per sentence. Vary length deliberately — a short sentence after two long ones creates rhythm.
- One idea per paragraph, each paragraph 2-4 sentences, so the avatar has natural reset points.
- No tongue-twisters, no clustered sibilance, no words with ambiguous pronunciation.
- Mark [GESTURE: ...] and [PAUSE] cues between paragraphs.
- Conversational register: contractions, direct address, no corporate abstractions.

In practice: The 18-word cap is the single biggest quality lever in avatar video.

One script, many languages, without literal translation

Localise this avatar script into [LANGUAGES]. Do not translate literally.

For each language: adapt idioms and examples to something locally familiar, adjust formality to the local business norm, keep sentences under 18 words after translation, and flag any term that should stay in English (product names, technical terms).

Note where the runtime will change significantly — some languages run 20-30% longer.

Script: [PASTE SCRIPT]

In practice: The runtime flag matters — a 3-minute English script can become a 4-minute German one.

Deciding what sits beside the avatar on screen

Break this avatar script into scenes. For each: the spoken lines, the avatar's framing (full body, waist up, close), the on-screen support (slide, screen recording, chart, b-roll, or nothing), and the 3-6 words of on-screen text.

Rule: never leave the avatar alone on screen for more than 20 seconds without a visual change.

Script: [PASTE SCRIPT]

In practice: The 20-second rule is what stops avatar video feeling like a hostage tape.

Sales and product avatar video

For a product avatar video about [PRODUCT] aimed at [AUDIENCE], write a 45-second segment that names the strongest objection a sceptical buyer has, states it plainly in their words, and answers it with one concrete proof point.

Do not soften the objection. Do not answer with a feature list. Do not claim anything I have not given you.

Proof points available: [LIST]

In practice: Naming the objection out loud outperforms avoiding it, especially in a synthetic delivery.

Final cleanup before rendering

Prepare this script for avatar rendering. Output a table of every proper noun, acronym, number, and unusual word with a phonetic spelling. Then return the full script with pauses marked, emphasis words bolded, and any sentence over 18 words split.

Do not change meaning or add claims.

Script: [PASTE SCRIPT]

In practice: Run this last, right before you paste into the avatar tool.
