If you spot your child speaking into their Nintendo 3DS family system, don't worry – the handhelds feature a built-in microphone. Some games call for players to speak or blow into the microphone to affect game events.
The microphone can also be used to communicate via Game Chat with others while playing certain Nintendo 3DS games online. A person can only speak to another player on their friend list, so your child will not be able to use Game Chat with anybody that they don't know.
