The Test of Articulation and Phonology (iTAP) is a standardized measure for assessing the articulatory and phonological abilities of monolingual speakers of English. This evaluation is to be considered as part of a full speech evaluation to include: measures of intelligibility, considerations for second language influence, and considerations for the age of acquisition of each phoneme. The iTAP was developed by Barbara Fernandes, Ellen Kester, Mary Bauman, and Scott Prath. The iTap can be used with individuals of all age groups. The iTap is compatible with the iPad running iOS 8.1 or above.
