Passive voice is often used in formal writing to make statements more objective and impersonal. In formal contexts, passive voice can convey a sense of professionalism and detachment, which is appropriate when discussing complex or sensitive topics. It can also help focus the reader’s attention on the action or the result of an action rather than the doer of the action.

In comparison, passive voice is less common in casual conversations because it can make the communication less direct and more detached. Casual conversations typically emphasize personal connections and direct interactions, so using passive voice can create a barrier between speakers and listeners.

The impact of passive voice on tone and formality varies in spoken and written language. In written language, passive voice can enhance formality and neutrality, which is suitable for academic or technical writing. However, in spoken language, passive voice can make communication less engaging and less clear, potentially leading to misunderstandings.

Overall, the nuances of using passive voice in formal versus informal contexts revolve around the balance between objectivity and personal engagement, as well as the desired tone and formality of the communication.
