| Status | Completely developed test. |
| Goal | Diagnostic and comparative evaluation of the intelligibility of sequences of one or more consonants in initial and final word position. |
| Languages | American English [Spiegel et al. (1990)]. |
| Items | Fixed set of 312 CVC-items, containing two tokens of nearly all onsets (N=62), nearly all plain offsets (N=63), and a subset of 31 (out of 111) offsets with phonetic affixes . Of each pair of tokens one is presented in a meaningful word, the other in a meaningless, but phonotactically legal word. Examples: meaningful versus meaningless onset swan versus swog, plain offset warmth versus dorth, offset with affix dropped versus globbed. |
| Procedure | Open response identification in normal spelling. |
| Time | With all 312 items and an interstimulus interval of 6 sec (recommended), about 40 min per synthesiser. |
| Analysis | Manually. Intelligibility is expressed as the percentage correct onsets and offsets or the percentage of cases where the phonemes occurring in the response correspond with a phoneme in the stimulus. |
