Record the line and these fill in.
Could you have delivered that line?
A voice over game hands you a scene with its original audio and asks you to take that audio's place. You hear the line, then you say it. That is the whole voice over game format, and it is older than the software: a voice over game is what a dubbing booth does, minus the booth. The scene plays one line at a time; Replay plays the original, Record counts down from three, and the picture rolls while you speak. If a line comes out wrong you take it again, and only that line changes — retakes in the voice over game are free, unlimited, and nothing is committed until you export.
The part people get wrong on first contact is assuming a voice over game works like karaoke. It does not. Karaoke scores pitch against a melody. A voice over game has no melody to score, so it measures delivery instead — the timing of your entrance, the length of your reading, and how much of the line you covered. You can be completely off-key in a voice over game and still score a hundred. Getting a laugh out of four seconds of dialogue is an acting problem, not a singing one.
One more thing separates a voice over game from a soundboard or a clip editor: it scores you, so there is something to beat — your last take, the original, or a friend. The format grew up in modding communities, where people packaged scenes by hand and traded them for The Choicer Voicer, the desktop game that popularised it; this voice over game online reads that same community format, so every pack plays here in a tab, and the finished MP4 is assembled on your device with your takes mixed over the scene.
Whether you came in with the original and moved with it. The waveform under the line shows both takes stacked — the original in grey, yours in green, any gap in amber — so you see the mistake before you read the number: the fastest way to learn what the voice over game is asking of you.
Whether your reading ran as long as theirs. This is the number that drops while a take sounded fine: a reading that is right in every way except length still loses points, because the dub has to fit the picture.
Whether you spoke across the whole line or left a hole in it. The voice over game measures when you speak and for how long, not how loud — you can shout or murmur and coverage does not care, until a whisper drops so low it stops registering as speech.
The three combine into one score per line, and those three are the entire scoring model of the voice over game — nothing else hides behind them. Beat the number, or send it to a friend and let them try.
Most of a voice over game's scoring is a black box you learn by feel. Here is ours, opened up: one real 1.75-second line from the library, run through the same engine that grades you, deliberately deformed one way at a time. Measurements, not estimates.
| The take | Score | Rhythm | Duration | Coverage |
|---|---|---|---|---|
| Spot onthe original played back | 99 | 100 | 100 | 100 |
| Started 0.3 s lateeverything else perfect | 98 | 97 | 99 | 100 |
| Rushed it by 20%same words, faster | 91 | 95 | 81 | 100 |
| Whisperedat 5% of the original level | 91 | 89 | 93 | 100 |
| Dragged it out by 25%same words, slower | 89 | 90 | 83 | 100 |
| Dropped the middlea quarter of the line missing | 87 | 78 | 100 | 100 |
| Shouted2.5× the original level | 99 | 100 | 100 | 100 |
Two things in that table are worth knowing before your next take in the voice over game. Shouting costs nothing and whispering costs eight points; a late start is almost free, because the engine trims silence before it listens. And the most expensive mistake is not rushing, it is leaving a gap in the middle, which takes rhythm down twenty-two points on its own.
The practical read for any voice over game: commit to the whole line. A confident wrong reading beats a hesitant right one every time — rushing by a fifth still scores 91, while going quiet in the middle scores 87. No other voice over game online publishes this table, which is the honest reason it is here: the numbers come out of the engine, so they cannot drift from what you experience in the stage above.
The library is a starting point, not a ceiling. Upload an MP4 and the maker splits it into timed lines and hands it back as a playable scene, so this voice over game can be pointed at anything you have the right to use: a clip you filmed, a sketch you wrote, something off your own screen. This is the one part that costs credits, because it runs real transcoding work; playing never does.
Make a scene from a video →The social form this voice over game takes is a challenge: you dub a scene, share the link, and whoever opens it attempts the same line. Both takes get the same three numbers, so the argument about who did it better has an answer. Nobody needs an account to attempt one.
Record a line to share →The voice over game builds the file in your browser rather than on a server, which has a side effect worth naming: your voice never travels. There is nothing to delete afterwards because there was never a copy anywhere but your own machine. Not every voice over game online can say that.
In person a voice over game works differently and better: one phone, one scene, and the device goes round. Four lines each is about the right length before someone wants a turn. For a group, pick a scene with two characters and split them.
There are two ways to reach this format, and they are not the same trade. A desktop voice over game gives you local files and no network at all. A voice over game online gives you a link, which is the whole difference when someone wants to hand the format to a friend. The case against a voice over game online used to be that it could not do the heavy part — mixing your takes over the video and encoding an MP4. That stopped being true.

A voice over game online that runs recording, scoring and video encoding in a browser tab is doing real work, so here is the test log instead of "works on any modern browser". Every row below has been run for real.
| Environment | Record and score | Export the video | Notes |
|---|---|---|---|
| Desktop Chrome (macOS, Chrome 151) | Measured | Measured | The voice over game exported a 39 s scene in 3.9 s; the 197 s worst case in 11.7 s, which is where the seventeen-times figure comes from. |
| Desktop Safari | Measured | Measured | The voice over game works end to end. Safari cannot decode Ogg audio, so some imported packs will refuse there by design; library scenes are encoded for it. |
| iPhone and iPad (Safari) | Measured | Measured | Record, score and export on a real device. Add it to your home screen and the voice over game opens like an app. |
| Android (Chrome) | Measured | Measured | Record, score and export on a real device. Install the voice over game as an app from the menu. On a phone, a quiet room matters more than a good microphone: the scoring cares about timing, not fidelity. |
fix 01 · the browser never asked for permission
Check the padlock in the address bar. If the microphone is blocked for the site, the prompt will not come back on its own — clear it there and reload. This is the single most common reason a voice over game appears to do nothing when you press record.
fix 02 · permission granted, nothing heard
Another application has the microphone, or the wrong one is selected. Close the other app and reload; on a laptop, a video call left running in another tab is the usual culprit. If live input works but the recording is silent, the input device chosen in the operating system is not the one you are speaking into — switch it at the system level, then reload the voice over game.
fix 03 · the stage is blank or stopped
Reload the voice over game once. If it persists, the scene's media did not finish arriving; picking a different scene and coming back usually clears it.
fix 04 · scores look lower than the take sounded
Read the three numbers separately. A voice over game score that drops while the take sounded fine is almost always duration — the section above has the measured cost of every mistake, and length is the one your ear forgives first.
