The purpose of the Chapel Hill Multilingual Intelligibility Test (CHMIT) is to estimate overall speech production ability in adults with speech difficulties. It was developed for people who may have difficulties reading or producing sentences (e.g. people with aphasia). Tests have been, and continue to be, developed in different languages.
It takes 5 minutes to administer the CHMIT and 5 minutes to score it. Each version of the test includes 600 unique words, but only 50 words are used each time the test is administered. The words are organized in sets that are phonetically similar but also as diverse as possible. This way we can minimize the risk that listeners learn the content of the test or use logic to predict the words they hear.
One word from each of the 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. We have found that a write-down scoring procedure is most useful. For test-retest purposes, it is sufficient to have a single listener score the test, but to ensure strong reliability, we recommend using three listeners.
The test is meant to be administered via software. Because it is administered with both audio-recorded and printed models, it is not necessary for the test administrator to know the language that is tested. Fluency is, of course, required for the listeners who score the test.
Over the years, we have used different software to run the CHMIT. In the near future, you will be able to download one version of the the software by following the instructions below. We also provide pdf files showing test content for different languages. These 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.
We are currently collecting norms for the CHMIT in Spanish and Greek. Software modifications have been made to accommodate international font. This software is not yet available for download. We are pursuing modifications to a tablet format to make it as practical as possible for speech-language pathologists.

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.
