You can always paste the text into chatgpt and ask it to repost the taxt as a child, or as a student, or as a physicist. It does very well at that sort of answer.

How about scanning the original colour, find out what the actual pantone colour is, then ask to put say PANTONE 15-6437 TCX Grass Green, into the ai program, box and nothing comes out for cladding, but general wood colour is Pantone P 31-16 C Color | #A2542C. Maybe this helps?

You will find it extremely difficult to replace the text only in a song. First of all, you can only replace the text in a song, period, you will not be able to reinstate the music or background ambiences that surround the words....do you understand what i mean, Pavel? The only way you will be able to replace the words in a song is to separate the music from the words, to create an acapella version of the song. Adobe Audition does this very well. Therefore, you will have the original music track and a separate voice track. I don't know what ai version that will change a voice track only, otherwise, you're trying to run before you can walk and I think you are asking too much of ai at the present time. If this project is for gain, or commercial use, then you will definitely be infringing a copyright issue here, Pavel, so be careful.
