The International Speech Screener (ISS, McLeod, 2013) is a 50-item picture-naming task that samples all English consonants and six English consonant clusters on two occasions in word-initial position. Words vary in length and stress. The ISS was designed to ensure that there were two examples of each word-initial consonant. Most pairs of words for each word-initial consonant contained a monosyllabic word and a bisyllabic or polysyllabic word (e.g., dog, dinosaur). Within these words most English vowels, within-word consonants, word-final consonants, and some word-final consonant clusters are sampled. The ISS is presented via PowerpointTM with one picture per slide. An audio-voice recording of the target word is available on each slide and played during the imitation condition.
