your fake world sucks. 

I only extracted the singer's voice from the song and I want to translate his voice into another language with his voice
 The original What software or website do you recommend?

AI hasnt quite got this capability yet, so you will have to translate it and get a singer. Software cannot do everything. Even with software, you have to lots of work. So if i isolate paul mccartney’s voice i cannot make that voice sing it in German. Not possible …….. yet. Its even worse because when you record the foreign language version there are often more syllables, so it doesn't sound right. Listen to Abba singing in other languages. The song is very different.

Is that not for speech? I cant find any similar version yet, for singing? Its also not cheap.
