AI Voice Isolator: Extract Clean Speech from a Video
Drop in a video or a recording and the AI pulls out the speech as its own clean track. Music, room tone, traffic and crowd noise all stay behind, and you get the video back with the picture untouched. On a computer it runs free in your browser, on this device: nothing is uploaded and no account is needed. For longer files, or a browser that cannot run the model, switch to Cloud: your first 10 credits are free, which is 10 minutes here.
Drop a video or audio file or browse your device
MP4, MOV, MKV, WebM, AVI, MP3, WAV, M4A and more
Up to 20 files at once
This browser cannot run the AI model on its own: it needs WebGPU and at least 8 GB of memory. Switch to Cloud to run this file.
Free on this device where the model can run. In the Cloud, you pick how long the result is kept.
Bigger files? Run it in the Cloud
This tool runs on this device for free. For a file over the device limit or a long recording, the same tool runs on our servers, with up to 5 GB per file and 6 hours of audio, faster, and with your files kept for up to 7 days, or as long as you choose with any pack or plan. From 1 credit a minute, with 10 credits free when you create an account.
How to extract the voice from a video
Drop in the file and the AI separates speech from everything else in the mix. On this device that runs free in your browser with no upload. You get back only the spoken voice, clean enough to transcribe, dub or drop into a new edit.
- Drop in an MP4, MOV, MKV or WebM, or an MP3 or WAV.
- The AI lifts the speech out as its own stem.
- Preview it, then download the isolated voice.
Why this instead of the background music remover
It keeps the speech and nothing else: music, ambience and effects all come out. The Background Music Remover runs the same model; this page is for when the voice is the only thing you plan to use.
Speech only, nothing else
Music, effects, ambience and room tone all come out, so you get the speech on its own: inside the video you dropped, or as an audio file when you dropped audio.
Built for transcription
Automatic transcription and captioning fall apart on a noisy mix. Feeding a clean speech stem in first is the single biggest accuracy win you can get.
Video in, video out
Drop a video and you get a video back with the picture untouched. Most voice extractors hand you a bare audio file and leave you to rebuild the clip.
Ready for dubbing and voice work
A clean dialogue stem is the starting point for translating, re-timing or replacing a voice track without the original mix fighting you.
Rescues bad location audio
A talk filmed in a busy hall or an interview beside a road becomes usable when the speech is separated out rather than filtered.
Free in your browser
This device runs the AI model on your own computer, so it costs nothing: no account, no upload, no credits, as many files as you like. The Cloud, for long files, starts every new account with 10 credits for free, which is 10 minutes of this tool. No card needed.
How it works, step by step
Four steps from a noisy mix to a clean spoken track.
Add your file
Drag a video or audio file onto the box above, or click to browse. MP4, MOV, MKV and WebM all work, as do MP3, WAV and M4A.
Pick This device or Cloud
This device runs the AI in your browser: free, no account, nothing uploaded, on a browser with WebGPU and at least 8 GB of memory, up to 15 minutes of audio per file. The Cloud runs it on our servers for longer files: sign in, and your first 10 credits are free.
Let the model isolate the speech
It listens to the whole track and separates the spoken voice from the music, the effects and everything else sharing the mix.
Preview, then download
Check the result before you commit. If the voice is clean, download it and use it wherever you need it. On this device your file has not left it; in the Cloud the files are deleted on the schedule you picked.
What people use it for
Any job where the words matter and nothing else in the recording does.
Prepare audio for transcription
Captioning tools guess wrong when music and chatter sit under the dialogue. Isolate the speech first and the transcript comes back close to accurate the first time.
Pull a quote from a clip
You want one spoken line from a video that has a soundtrack over it. Extract the voice and you can use the quote without dragging the music along with it.
Dub or translate a video
Re-voicing a video is far easier with a clean dialogue stem to time against, instead of a finished mix where the words are buried.
Rescue an interview
You recorded beside a road or in a busy room. Separating the speech gives you something usable where a noise filter would only smear it.
Build a podcast from video
Turn a filmed conversation into an audio episode by taking just the voices, without the location sound coming with them.
Isolate a voice for analysis
For research, accessibility or review work, a clean speech track is easier to study than a full mix with everything competing.
What it handles well, and what it does not
| Works well on | Struggles with |
|---|---|
| One clear speaker over music or room noise | Several people talking over each other throughout |
| Interviews, lectures and pieces to camera | Whispered speech buried under a loud mix |
| Filmed conversations you want as audio | Audio already clipped or heavily distorted |
| Clips where you only need the words | Recordings where you wanted the effects kept as well |
Which of our three AI audio tools you want
| If you want | Use this |
|---|---|
| The music, without the voice | AI Vocal Remover. Returns the soundtrack with the vocals removed. |
| Your talking on the video, minus everything else | Background Music Remover. The same model and the same clean voice, on the page written for taking the music off a video. |
| Only the spoken words, nothing else at all | This tool. The same clean voice, on the page written for pulling the speech out of anything. |
| Every sound gone | Mute Video, on the homepage. Runs on this device, no upload, no account. |
| A steady hum or hiss reduced | A plain noise filter is enough. You do not need AI separation for that. |
The two voice tools and the vocal remover share one engine pointed two ways: at the voice, or at everything but the voice. Pick by what you want to keep, not by what you want gone, and the choice is usually obvious.
Came here to take the music off a video? The background music remover is the same model, written for that job. Is it noise rather than music? The background noise remover cleans hiss, hum and wind off the speech.

Frequently asked questions
Yes, in your browser. Pick This device and the AI model runs on your own computer: no account, no upload, no credits, and it stays free however many files you run. It needs a browser with WebGPU and at least 8 GB of memory, handles up to 15 minutes of audio per file, and downloads the model once, on the first run. The Cloud is for longer files and for devices that cannot run the model: every new account starts with 10 credits for free, which is 10 minutes of this tool, no card needed. The Cloud costs 1 credit per minute, and every started minute counts, so a 2:30 clip is billed as 3 minutes.
