I've created a video , however, I said something inappropriate in the video so I decided to remove all voice from the video, making it a silent video.
I cannot retake the video again, how can I remove all the voice in a video. It's in mp4 format

I've edited hundreds of videos that contained swearing, etc. To fix these you can use a video editor (NLE) and simply mute the audio track when you want to get rid of the audio.
However, if you want to be more professional, you can replace the offending audio with audio which appears in another part of the video. If you can find some sections of the audio which are simply background noise, you can use that to replace the audio. If you feather the in/out points, the viewer won't even notice the missing audio.
Another trick is to select the offending audio and then reverse it so it plays backwards.
There are dozens of other ways to fix the audio, some of which can produce pretty amazing results. Here is an example of some of that magic. I was given all the game films from a football team's championship season and asked to produce a highlights music video. Most of the music they asked me to use contained lyrics that could not be played at the school during the year-end awards ceremony. I've queued up the following clip to begin playing when the chorus starts. During that chorus, the words which repeat are "when will you n**** learn." Note that I was able to seemingly get the music to continue, but the words are completely muddled and are no longer offensive.

There are a lot of other filthy words in this video, and I removed them as well. If you click on the following you can compare the lyrics with what you hear:

BTW, this is not my channel and I did not upload it, so I was not responsible for the lousy, fuzzy video encoding. It is, however, my editing.

ffmpeg -i "originalvideo.mp4" -c:v copy -an "videowithoutaudio.mp4"
-c:v copy = copy the video, do no re encode, etc..
-an = kill the audio, do not copy
The resulting MP4 will have only a video stream, no audio stream. However, Ive seen players have problems with videos with such formatting.
