Make a Voiceover Video: Record Your Voice or Use AI Voices

A voiceover video maker turns a script or a spoken take into narration that sits on your video timeline, ready to sync with the picture. EchoWave lets you do this two ways: record straight from your microphone in the browser, or type a script and generate a natural voice with AI. Either way, the voice lands on its own track next to your footage, music, and captions, so you can trim it, move it, and balance the volume before you export. It is free to start, runs entirely in your browser, and needs no download or signup to try.

Two ways to add the voice

There are two ways to put a voiceover on your video in EchoWave, and you can pick whichever fits the project.

Record with your own voice. Grant microphone access once, then record narration straight in the browser while your video plays, so you can speak in time with the action. This is the same recording workflow covered in detail in our guide on how to add voiceover to video, including tips on mic setup, room choice, and balancing narration against your original audio.

Generate a voice with AI. Type or paste your script and pick from 63 AI voices spanning different genders, accents, and speaking styles. Preview a voice against your script before committing, and if none of the presets sound right, clone your own voice from a short recording and reuse it on every future project.

What you can make with a voiceover video maker

Narration turns raw footage, a screen recording, or a slideshow into something a viewer can follow without reading. Common projects include:

• Tutorials and explainers: narrate each step of a process while a screen recording or product shot plays, so viewers can follow along instead of pausing to read captions.
• Product demos: walk through a feature or product without needing an on-camera presenter, useful for marketing teams shipping a demo video on a deadline.
• Faceless YouTube and Shorts channels: pair stock or b-roll footage with a scripted AI voice, one of the most common formats for channels that never show a face on camera.
• Presentations: record a screen capture of your slides, then add narration timed to each transition, so the deck plays back like a finished video.
• Real estate walkthroughs: layer a calm, professional voiceover over a property tour to point out rooms and features without anyone standing on camera.

Timing the voiceover to your visuals

Once the voice track is on the timeline, it behaves like any other clip. Drag it left or right to line up a line with the moment it describes, split it if you need a pause, or trim the head and tail to tighten a take. Because the voice sits on its own track, it never overwrites your original footage or music.

Volume matters as much as timing. If your clip has useful ambience or music underneath, lower that track so the voice sits clearly on top instead of competing with it. If the original sound does not add anything, mute it and let the voiceover carry the video on its own.

Pair captions with your voiceover

A large share of viewers watch with the sound off, especially on social feeds, so a voiceover works best alongside captions rather than instead of them. Once your narration, recorded or AI-generated, is on the timeline, run auto captions and EchoWave transcribes the voice track into synced subtitles you can style to match your video.
