Interesting question. Your question can be read as "Is there any programming language that is easily readable by humans?", OR ELSE as "Is there a human language that can be used for programming?". All the answers here have focused on the former, so let me try answering the latter.
Have you heard of Sanskrit? It is an ancient Indian language on which modern Indian languages like Hindi are based.
wiki/Sanskrit
I've been hearing for years that it is precise and complete enough to be used, as it is, as a high-level language on a computer. Ofcourse, you need a compiler to convert Sanskrit instructions to machine language. I know the script & yes, it is precise (entirely phonetic so you never have to ask "how do you spell that"), but I don't know the grammer well enough.
This is completeley anecdotal, so I don't vouch for the accuracy of this. Just wanted to share what I know regarding this. :-)
