How to Create a Product Video Voiceover on Your Phone
With Narrator's Voice, you can make a voiceover for a product ad or video on your phone. Write a short script, choose a fitting voice, generate the audio, and bring the MP3 into your video editor. Before publishing, check that the narration explains the main benefit and fits the footage.
This workflow works for product demos, presentations, and social media videos. Narration helps organize the message, while product claims still need to be accurate and match what the business provides.
Choose one main message
Pick one point the video needs to make clear. It might explain who the product is for, what problem it solves, or what viewers should do next. Trying to fit every detail into a short video can make the narration feel rushed.
A simple starting structure is to introduce the situation, explain a benefit with a verified detail, and end with a clear action. Keep any important conditions, limits, or requirements in the script.
Write to the length of the footage
Watch the footage and note how long each shot stays on screen. Write a sentence for each important moment, then read the script aloud. If the narration does not fit, shorten the text before trying to speed up the voice.
Check numbers, product names, and technical terms. An abbreviation may be clear on screen but confusing when spoken. Generate a sample with those passages to check how they sound.
Choose a voice and generate the audio
Match the tone to the message and audience. A demonstration that explains steps calls for clear delivery. A more relaxed ad can use a lighter pace, as long as the words remain easy to follow. Try a few voices with the same passage before generating the full narration.
In Narrator's Voice, type or paste your script, choose a voice, and generate the narration. You can adjust the wording, add pauses, and include sound effects or background music. Save the audio as an MP3 for editing.
Edit, review, and publish
Import the MP3 into your video editor and sync the narration with the scenes. Leave room for the footage to show the product. If you add music, keep its volume low enough for the voice to remain clear.
Watch the full video, preferably on your phone. Check that each claim can be verified, prices and terms are current, and you have permission to use any images, music, or third-party brands. Commercial use of audio made with Narrator's Voice is allowed, including in ads and client projects. You still need the necessary rights for the other material in the video.
