It is indeed English, but it is used all over the world. It is the name for laptops for wireless communication, both for professional use and toy. They have as a characteristic a half-duplex channel, where each handie transmits in turn while the others receive it. The name is taken from the verbs to walk ( "walk") to talk ( "talk") and in the original would be walkie-talkie, but in Spanish it is preferred to avoid the hyphen. See transceiver .
