Choose a voice for an AI product ad

A voice choice works when the delivery helps the approved words land. Start with the line’s purpose: a quiet observation, a clear explanation or an energetic invitation. Do not ask a voice to create credibility by impersonating a familiar creator, or let an appealing performance turn a modest product description into a testimonial.

Rehearse the line before selecting the delivery

Hypothetical example: a creator presents a photographed notebook and says, “Here is the cover, and here is the binding.” The photos support those visible features. They do not confirm paper quality, page count or durability. Read the sentence at a natural pace while opening the cover, then leave time for the final product frame.

If the line only fits when rushed, shorten it before looking for a faster voice. Breaths and pauses are part of believable delivery, particularly while someone handles an object. The dialogue timing guide uses rehearsal rather than a guaranteed words-per-second rule.

Compare voices with the same job in mind

A calm explanation may need a small pause before an identifying feature. An energetic introduction may need a bright opening followed by slower product words. Describe that delivery plainly; “viral influencer voice” is less useful than “conversational, clear, with a brief pause before binding”.

Use a voice you are allowed to use

In fairytale video, choose a library voice or record or upload a sample you have permission to use. The voice is selected in the character’s dialog. When the ad has spoken lines, the render uses the selected sample as a reference alongside the character images. That reference guides sound; the approved dialogue field determines the words.

A sample is not permission to imitate someone without consent. Keep a simple note about where a custom sample came from and who authorised it. For a fictional creator, choose a delivery that suits the scene without claiming the person has actually used the product. See casting from a brief for the visual side of this decision.

Review speech separately from appearance

Watch once with sound on and compare every spoken word with the approved line. Then check whether visible mouth movement agrees with the delivery. Listen for added slogans, misplaced emphasis, invented words and a change of voice between stages. A good face match does not make an incorrect sentence acceptable.

Request captions only when you want to transcribe the finished video. Check those words too; captions should not conceal a speech error. The talking-ad guide covers dialogue, lip sync and the final listening pass.
