Place it directly over the word you need to hide, then follow it with a Vine Boom to underline the reveal, or a dramatic dun dun dun when the hidden detail is a spoiler.

This is one flat, high electronic tone that stays level for about five seconds, with no rise, fall or break in the middle. It feels cheeky and deliberately fake, turning a hidden word into a small joke because listeners immediately know something was covered up. The tone comes from broadcast television, where it replaced words that could not be aired.
