Ludwig's WRAP-UP
In summary, "informal speech" is a common and acceptable phrase used to describe a relaxed, conversational style of communication. As noted by Ludwig, its grammatical status is correct, and it appears frequently in News & Media and Wiki sources.

Alternative phrases such as "casual language" or "colloquial language" may be more appropriate depending on the specific nuance you wish to convey. Ludwig's analysis indicates a generally informal register, making it suitable for everyday conversations and creative writing, but less so for academic or formal business contexts without specific analytical intent.
