Call your home anonymously to check on your nanny or babysitter. She won’t recognize you if you use one of the voice changers available in the market today. Many voice changers can change and enhance voice in different ways such as switching sound from female to male.

Although the voice changing technology can be used for fun, it is very helpful when monitoring your home or even hiding you identity when someone you don’t know calls you. A lot of voice changing devices are very affordable as basic ones cost less than $100.
