Each industry has its own jargon, the way people like us say things. If you are sitting in a meeting and trying to pitch your services as a senior management consultant or lawyer, lowering your voice and using the jargon will show that you are one of them.

But being one of them is only one part of the pitch. Being understood is the other one. And for this purpose, it is probably better to keep things human. Especially if you do not have a lot of time: the cover email of a pitch deck, the description paragraph of a conference panel.

Be understood first, then worry about blending in.
