Speech Generating Device - Selection Set and Vocabulary

Selection Set and Vocabulary

The selection set of a SGD is the set of all messages, symbols and codes that are available to a person using that device. The content, organisation, and updating of this selection set are areas of active research and are influenced by a number of factors, including the user's ability, interests and age. The selection set for an AAC system may include words that the user does not know yet – they are included for the user to "grow into". The content installed on any given SGD may include a large number of preset pages provided by the manufacturer, with a number of additional pages produced by the user or the user's care team depending on the user's needs and the contexts that the device will be used in.

Famous quotes containing the words selection, set and/or vocabulary:

    It is the highest and most legitimate pride of an Englishman to have the letters M.P. written after his name. No selection from the alphabet, no doctorship, no fellowship, be it of ever so learned or royal a society, no knightship,—not though it be of the Garter,—confers so fair an honour.
    Anthony Trollope (1815–1882)

    It’s the set of the sails and not the gales,
    That bids them where to go.
    Ella Wheeler Wilcox (1850–1919)

    My vocabulary dwells deep in my mind and needs paper to wriggle out into the physical zone. Spontaneous eloquence seems to me a miracle. I have rewritten—often several times—every word I have ever published. My pencils outlast their erasers.
    Vladimir Nabokov (1899–1977)
