The purpose of the Chapel Hill Multilingual Intelligibility Test is to measure overall speech production in adults with speech difficulties. It was developed for individuals with left hemisphere injury with the intention that it be employed in a word identification test paradigm. The test includes 600 different words. One word from each of 50 phonetically similar, yet varied, word sets is selected at random and speakers say these words by repeating a spoken or recorded model. The words are recorded and later presented to listeners for identification. To determine the percentage of words that is understood, either a write-down (orthographic transcription) response procedure or a multiple-choice response procedure may be used. For multiple-choice testing, words from each set may be used as response alternatives. In our research, we have used custom software to elicit and record speech samples and to collect listener responses, but other applications are also possible. Tests have been developed in several languages, using similar procedures. These tests may be downloaded for educational, clinical, and research use. We hope you will find them useful. Please note that commercial use is prohibited (see copyright statement). Additional tests will be posted in the future, as they become available.

The development of the English monosyllabic word test was made possible by a grant from the National Institute on Deafness and Other Communication Disorders (NIDCD, R03DC006163). First authors of tests in languages other than English were students in the UNC Chapel Hill Department of Allied Health Sciences, Division of Speech and Hearing Sciences. The contents of the tests are solely the responsibility of the authors and do not necessarily represent the official views of the NIH or the UNC-CH Department of Allied Health Sciences.
