Here are some examples:
* "The company sent an ad vocem message to its disgruntled customers." (The message was specifically tailored to address the concerns of those particular customers.)
* "The politician delivered an ad vocem speech to the farmers' union." (The speech was directly addressing the issues important to the farmers' union.)
* "The ad vocem campaign targeted young adults who were interested in technology." (The campaign was specifically designed to appeal to this particular demographic.)
In these examples, "ad vocem" highlights the directness and personalization of the communication. It suggests that the message is not intended for a wider audience but rather aimed at a specific group or individual.
