While many studies of word frequency use have been conducted with normal individuals, it is difficult to determine the extent to which this reflects the speech of a given client or situation. Even the top fifty most frequently used words may differ by more than 50% between different word frequency studies. Although some words are consistently high frequency across all settings, frequent variation in vocabulary production is reported between population samples discriminated by age, mode of output, task, setting, sampling method, and units of analysis. A wordset for an augmentative communication system is ideally tailored to a client's age and educational level but applicable across settings and communication modes; frequency information for a wordset should then be based on an appropriate sample(s) and augmented by information on vocabulary variation across relevant settings/modes. This paper outlines considerations and available resources for vocabulary selections utilizing frequency data, based on an overview of a bibliography collected at the Trace Center, Madison, WI, of over 350 studies related to vocabulary frequency in normal individuals.
