People may not want to give information about who lives in their home to unknown callers for a variety of reasons. This information may be used by telemarketers who could then ask for you by name when they call again, scammers who might do the same, or people who are not interested in your welfare. Women living alone for instance may use the “we” instead of “I” to suggest more people living in a house, and can even opt for using the machine generated message or computer generated “male voice” instead of their own voice to increase their security at home. For personal security reasons, you might want to avoid indication of children in the home, too, and you certainly shouldn’t mention that you’re on vacation.

Pro Tip: Smile while you’re recording your greeting and your voice will sound pleasant.
When you’re recording an answering machine greeting for your home, or a voicemail greeting, some people like to keep it funny and light. They may record a message together, have one of their young children record, play silly music in the background or create some kind of a joke. While it’s fine to be funny, especially on a home recording, you should probably avoid being crude, particularly if you think children may be calling your home. Telemarketers may use any information given in an answering machine greeting.
