The Cluster-Based Rhyme Test (CBRT) is an open test for measuring speech intelligibility. Input to the test is a monosyllabic word. After generating its phonemic equivalent, the word is divided into C- and V-clusters. For each of these clusters five already defined phonetically similar alternatives as well as the correct cluster itself are activated. They are stored in a file. For the test, the activated cluster sets are arranged in a matrix: Each column consists of these alternatives, each row of the clusters in the same order as those of the input word. When the subject gets the stimulus acoustically, he/she has to identify the word and mark the respective cluster in each row.
