A screen recording can show every click and still leave the viewer unsure what changed. Narration has a different job from the cursor: it explains the decision, the result, and the next step. LOVO AI offers a browser voice studio for turning that script into MP3 audio, with a separate local video editor for pairing the track with a recording.
This walkthrough is based on the live interface and public product notes checked on September 28, 2026. The controls were inspected without running a credit-consuming generation, creating a voice clone, or exporting a video. The examples below are suggested scripts, not reported generation results.
Write around a visible result
Start with one small user task. For a dashboard demo, that might be finding an overdue item and changing its status. List the visible checkpoints before writing the narration: the initial list, the selected item, the changed field, and the confirmation.
Then give each checkpoint a short line. An illustrative opening could be: “Open the task list. Choose the overdue item, then mark it complete. The list now shows the updated status.” The wording identifies an action and its consequence without reading every button aloud.
Keep UI labels exact when the viewer needs to find them. Use ordinary spoken wording for everything else. A sentence copied from a specification often contains qualifications that are useful on paper but hard to follow while watching a moving screen. Move those details into accompanying text if they are not needed at that moment.
The studio accepts up to 2,000 characters per request. That is a useful reason to work in short sections, although it is a character limit rather than a guarantee about audio duration. Keep a plain-text copy of each script beside the screen recording so later changes remain understandable.
Review the voice and the generation boundary
The homepage has sample preview controls. The studio provides a voice selector, a character counter, and an estimated credit cost beside the generation button. At the time of inspection, the library listed 21 choices; availability can change with the connected service.
Use the samples to narrow the choice, then assess the actual script after generation. A sample cannot establish how a particular product name, acronym, or technical term will sound. For a walkthrough, intelligibility matters more than finding the most dramatic performance.
Speech generation uses ElevenLabs, and the studio says that submitted text is sent to that service. An account is needed to use credits. The site advertises a small trial allowance for new verified accounts; that should not be read as unlimited free generation.
The intended result is an MP3 that can be played in the page and downloaded. Treat that file as a reviewable artifact. Listen through the full take, revise the source text where needed, and save the accepted version with a descriptive filename.
Put the audio back into the recording
The video editor takes a local video and a voiceover audio file. It has separate controls for the voiceover level and the original video's sound. That makes it possible to lower incidental recording noise while keeping the narration audible.
Plan the recording around the accepted narration. The editor states that voiceover playback starts at the beginning of the video and that export ends with the video. A track with an essential final sentence after that endpoint will need attention before export. Do not assume a full timeline editor, automatic cuts, or automatic captioning from these controls.
The stated output is WebM. Export plays the video from start to finish, so the page says it takes roughly the video's own duration. Browser codec support varies. Check whether the next destination accepts WebM before making it part of a delivery checklist.
Keep one acceptance checklist
Review names and technical terms, confirm that each spoken instruction matches the visible UI, and check that the final action finishes before the video ends. Listen to the mixed track, not just the isolated MP3. Also confirm that the file format works for the place where the demo will be shared.
Voice cloning is optional. The studio includes a speaker-permission confirmation; a walkthrough can use a library voice without supplying a personal recording. The practical deliverable is a reviewed script, an accepted audio take, and a video whose visible sequence matches the words.
