Typical devices are the size of a hand-held calculator with an alphabet keyboard.
Students type the word they are trying to spell and the keyboard displays a range of possible choices. More advanced ones offer definitions of the words, and some speak the word with a voice synthesizer. These are useful when your child is away from a conventional computer spell checker. In addition, the advanced features like the definitions and voice synthesis offer more cues to help her choose the correct word from among the array of choices.
