To make an AI voiceover for a product video, write a short script from approved product facts, choose a suitable voice and generate a small sample. Listen for pronunciation, pace and meaning before producing the final recording. Then place the audio against the actual footage and review the exported video.
The hardest part is often deciding what the narration should say. A product clip can show material, shape or movement. The voiceover should explain the information the viewer needs, without describing every visible detail or adding promises the product cannot support.
This guide uses an original fictional product example. The scripts and timing plans are illustrative, not recordings or results from a completed production test.
Start with the footage and the message
Write down three things before opening a voice tool:
- What the viewer should understand by the end.
- What the footage actually shows.
- What action the viewer should take next.
For a short introduction, choose one main message. If the video shows a cup on a desk, the narration might introduce the cup and invite the viewer to inspect its details. It should not claim to demonstrate heat retention, durability or ergonomics unless the footage and approved evidence support those claims.
Use your campaign brief as the factual source. Keep the same product name, offer and destination across the video, caption and landing page.
Write a script for the available time
Read the first version aloud with a timer. Word-count estimates are useful for planning, but the selected voice, pronunciation and pauses determine the actual duration.
Here is a script for Morrow Table, a fictional homeware brand. Its example Weekday Cup is a 350 ml ceramic cup with a matte olive exterior and a rounded handle:
Meet the Weekday Cup. Matte olive ceramic, a rounded handle and room for three hundred and fifty millilitres of your usual coffee or tea. See the details at Morrow Table.
The spelling of “millilitres” follows the example's chosen language style. Your version should match the audience and the pronunciation you want to hear.
If the narration runs longer than the clip, edit the message before increasing the speaking speed:
Meet the Weekday Cup. Matte olive ceramic for your everyday coffee or tea. See the details at Morrow Table.
The shorter script removes a specification without changing it. Put that specification in the product description if it remains useful to the buyer.
Avoid trying to fit the full product page into one short video. Fast delivery can make the recording harder to understand and leave no room for the viewer to see the item.
Choose a voice for the job
Listen to a sentence that contains the actual product name and the most difficult phrase in your script. A sample saying “welcome to our company” tells you little about how the voice handles your brand, measurement or technical term.
Consider accent, clarity, pace and the level of expression appropriate to the subject. A high-energy delivery may suit one announcement and distract from another. Choose by the message rather than by whether the sample sounds impressive in isolation.
ElevenLabs' text-to-speech guide treats voice and model selection as important influences on the output. Its controls vary by model. That is a reason to learn the settings of the tool you are using, not to assume that one set of values works everywhere.
Use voices and source recordings you are authorized to use. When considering a cloned voice, establish the permission and intended use first. A generic product introduction rarely needs to imitate an identifiable person.
Prepare three delivery directions
You can compare direction without changing the script. The following are instructions to try, not claims that every voice tool supports a separate direction field:
| Direction | Instruction | Listen for |
|---|---|---|
| Calm product introduction | “Clear, relaxed and conversational. Give the product name a little space.” | Understandable name and natural pauses |
| Concise demonstration | “Direct and practical. Explain the item without promotional emphasis.” | Clear facts without a rushed finish |
| Warm invitation | “Friendly and restrained. End with an inviting, unhurried CTA.” | Appropriate warmth without exaggerated enthusiasm |
If your tool does not support natural-language direction, choose a suitable voice and use its documented controls. Do not paste stage directions into the script blindly: a system may read the words aloud.
Generate a short sample before committing to a longer recording. Keep the script version and settings with each candidate so that the approved result can be identified later.
Fix pronunciation deliberately
Write a short pronunciation list for brand names, product names, numbers and unfamiliar terms. For example:
PRONUNCIATION NOTES
Brand: Morrow Table
Product: Weekday Cup
Capacity: say "three hundred and fifty millilitres"
CTA: say the brand name, not a long URL
Avoid: reading file names or stage directions aloud
Try the tool's pronunciation controls or supported dictionary when available. Otherwise, a carefully rewritten phonetic spelling can help, but keep it in the recording copy rather than changing the customer-facing product name.
Listen to the corrected phrase inside the whole sentence. A pronunciation fix that works alone may sound awkward when it joins the surrounding words.
Numbers deserve a separate check. “One twenty” could mean an amount, a model number or a time. Spell out the intended meaning when the context is ambiguous. Confirm that any price or offer in the audio remains valid for the publication period.
Place the recording against the picture
Use the actual generated duration to build the edit. For the fictional cup introduction, a simple sequence could be:
| Beat | Picture | Narration purpose |
|---|---|---|
| Opening | Clear product view | Name the cup |
| Middle | Surface and handle detail | Explain the relevant design details |
| Closing | Stable product shot and readable CTA | Invite the next action |
These are editorial beats, not fixed timestamps. A slower voice may need more time. A shorter clip may need a shorter script or fewer shots.
Export the audio and bring it into your video editor if your creation tool does not assemble the complete video. Preserve the chosen recording instead of regenerating it during each edit. Lower or remove background music if it competes with the words.
Add captions or a transcript so that the message remains available without sound. Review captions against the approved script and actual speech; an automatic transcript can miss names, numbers or short words.
For the visual production steps, use the product-photo-to-video guide. Generating a clip, recording a voice and editing them into a finished ad are separate tasks, even when one workspace helps with more than one of them.
Review the exported video
Listen and watch the final exported file, not just the voice preview. Check it on a phone at an ordinary listening level and inspect the version with sound off.
- Meaning: Every spoken claim matches approved facts.
- Names and numbers: The brand, product, amount and destination are correct.
- Timing: Important words are not cut off, crowded or placed after the relevant shot.
- Mix: Speech remains clear over music and effects.
- Captions: Text matches the recording and stays readable in the placement.
- Ending: The CTA remains visible long enough to understand.
- Product accuracy: The picture has not changed the product while the narration describes it.
Ask a reviewer what they think the product does after one viewing. If their answer includes a promise you did not intend, inspect both the language and visual implications. Misunderstanding can come from the combination, not just the words.
Budget for revisions and the completed asset
A voice sample is not the same as a finished video. Include script revisions, regenerated lines, video editing, captions and review time when planning the work.
Record the actual charge for each attempt. Some tools price speech by characters or usage units; the details depend on the service, model and plan. Check the displayed estimate and current terms instead of assuming every revision is free.
For AI Magicx paid work, usage is priced in mana. Review the selected model, voice, funding source and estimate before generating. A provider key can change who pays for supported model usage; it does not make every other step free or unlock a tool outside your plan.
Also check the terms for the particular voice and model before using the audio in an ad. Do not infer universal commercial rights from the fact that a file can be downloaded.
Troubleshoot a recording that feels wrong
It sounds like an advertisement for any product. Replace generic praise with one approved detail and a clear action. A better script often helps more than another voice setting.
It sounds rushed. Remove a secondary point, shorten a clause or give the video more time. Avoid increasing speed until the words are technically present but difficult to understand.
A brand name is wrong. Test a small phrase using supported pronunciation controls, then regenerate only the necessary material where possible.
A sentence sounds unnatural. Split it where a person would pause. Remove stacked adjectives and clauses that only work on a page.
The audio is good but the video feels disconnected. Match the spoken detail to the shot that shows it. Keep the final instruction on screen while the CTA is spoken.
The final mix hides the narration. Reduce competing music and check the export again. More expressive speech cannot solve a mix that obscures the words.
Use the brand voice template to keep the writing consistent, then explore voice creation in Studio for the recording stage. Start with one short script and approve a sample before producing the whole asset.
