Word replacement

Hi, I have the video attached and have tried to edit one word in it and replaced with the correct word. I have tried using Premier Pro and Audition but do not have the skills/experience to do this so the word replacement is seamless. I can replace it but not match the sound quality, depth etc. TBH I am not even sure it would work with the lip sync, but maybe an expert can make it work. It is ok as it is, just annoys me!

In this link is the video https://vimeo.com/864719936?share=copy#t=0 at 29 seconds the statement 'there becomes 'less' boxes needs to be replaced with the word fewer. The new word fewer is attached.

Please quote if you think you can do this seamlessly.
