Make your voiceover sound professional, without recording it again
Optimize voiceover rewrites your first take into clean, full sentences with no ums or false starts, then re-voices it in your own voice with studio-mic sound, still in time with every click on screen.
Where this fits
Braiv Capture
Braiv Capture is a native Mac app for tutorial videos. Talk through the task the way you normally would, and Capture rewrites the voiceover into clean sentences, re-voices it in your own voice with studio-mic sound, translates the audio and on-screen text, and lipsyncs your webcam. Then export to Braiv to package and publish.

Rewrite, not trim
Cutting the ums out leaves choppy audio. Rewriting them out does not.
Filler-word removers delete sounds from your recording and leave you with jumps and half-sentences. Optimize voiceover works from the meaning of what you said instead: it rewrites the script into clean sentences, then re-voices it.
Restarts become one sentence
"So you, um, wait, you go to, the settings" becomes "Open Settings."
Nothing important is dropped
The instruction you gave stays. Only the stumbles, repeats and detours go.
Your original is kept
Switch between Original mic and Optimized VO at any time in the editor.
What this does
What one click on Optimize voiceover changes
Voiceover optimization in Braiv Capture rewrites a rambling screen-recording voiceover into clean sentences and re-voices it with a clone of your voice and professional microphone sound, keeping time with the key moments of the video.
-
Clean, full sentences
Ums, repeats and false starts are rewritten out, so the voiceover reads like a script instead of a ramble.
-
Still your voice
Re-voiced with a clone of the person in the recording, or a voice you already saved in Braiv.
-
Studio-mic sound
Clean, even audio without the room echo and hiss of a laptop microphone.
-
In time with the screen
"Now click here" still lands on the click, so what viewers hear matches what they see.

Deep dive
Everything you need to know about Voiceover optimization
Why tutorials get re-recorded
Most tutorials are recorded three or four times. Not because the steps were wrong, but because the voiceover was: a stumble in the middle, an “um” every few seconds, a sentence that restarted twice. The usual fixes are to script and rehearse, or to cut the filler out on a timeline. One takes the spontaneity out, and the other leaves jumpy audio.
Voiceover optimization takes a third route. You record once, naturally, and Braiv Capture fixes the delivery afterwards.
How Optimize voiceover works
Click Optimize voiceover on a recording and confirm the voice. Capture then:
- Rewrites the script. What you said becomes clean, full sentences. The ums, repeats and false starts go, and the instruction stays.
- Re-voices it in your voice. By default the clone comes from the recording itself, for this video only. Or pick a voice already saved in Braiv Speech.
- Gives it a studio-mic sound. The new voiceover is clean and even, without the room and laptop-mic character of the original.
- Keeps time with the video. Key moments such as “now click Settings” stay aligned with the click on screen, so the tutorial still makes sense.
Your original is always kept. The Voiceover toggle switches between Original mic and Optimized VO, so you can compare them and export either one.
How to make a voiceover sound professional
Three things make a voiceover sound amateur: filler words, uneven sound and pacing that drifts away from the picture. People usually fix them with a script, a better microphone and a re-record. Optimize voiceover fixes all three after the fact, from the take you already have. For the sound alone, without changing any words, Enhance microphone cleans up the original recording instead.
Lipsync when you are on camera
If the recording includes your webcam, a new voiceover can make the presenter bubble look dubbed. Switch on Lipsync the speaker in the same sheet and Braiv matches your mouth to the new words. More in Braiv Lipsync for screen recordings.
The first step of every language
Translation in Capture starts from the optimized script, so your Spanish and Japanese versions inherit the clean sentences rather than the stumbles. Next step: full video translation. Voiceover optimization is part of Braiv Capture.

Frequently asked questions
How do I make my voiceover sound professional?
Record the tutorial naturally, then click Optimize voiceover in Braiv Capture. It rewrites what you said into clean, full sentences and re-voices it in your own voice with clean, even, studio-mic sound. You do not need a script, a better microphone or a second take.
How do I remove filler words from a video?
Most tools cut the um sounds out of the audio, which leaves jumps and broken sentences. Optimize voiceover removes them by rewriting the script and re-voicing it, so the result flows. Ums, repeats and false starts all go in the same pass.
Do I need to re-record my voiceover?
No. That is the point of the feature. Your first take is the input. Capture produces the clean version from it, and your original recording is always kept.
Will it still sound like me?
Yes. By default Capture clones the voice from the recording itself, for this video only, without saving it to your voices. You can also choose a voice you already saved in Braiv Speech.
How do I make my mic sound better without new equipment?
Optimize voiceover re-voices the whole script with professional microphone sound. If you want to keep your exact words, Enhance microphone cleans up the original recording instead, making it clearer and more even.
Does the new voiceover stay in sync with the video?
Yes. The optimized voiceover keeps time with the key moments in the recording, so instructions like "now click here" still land on the action they describe.
Can I keep my original voice track?
Yes. The original recording is never replaced. Switch the Voiceover toggle between Original mic and Optimized VO in the editor and export whichever you prefer.
What if I am on camera?
Turn on Lipsync the speaker in the Optimize voiceover sheet. Braiv matches your mouth movement in the webcam bubble to the new voiceover. See Braiv Lipsync in Capture.
Can I translate the optimized voiceover?
Yes, and it is the best place to start. Translation picks up the clean script, so the ums and restarts never reach the other languages. See full video translation.
How much does it cost?
Voiceover optimization uses AI Credits from your Braiv balance, based on the length of the video, and lipsync adds extra credits. Capture shows the cost before you confirm. See pricing.
