| Popis: | Several intelligibility tests are currently being used to evaluate speech‐communication systems. Individuals engaged in the development of such systems would often like to compare the performance of a system evaluated with one test with the performance of another system that has been evaluated with a different test. A study has been conducted to examine and quantify the relation between scores obtained with four intelligibility tests (the Harvard PB‐Word Test, the Fairbanks Rhyme Test, the Modified Rhyme Test, and the Harvard Test Sentences) for various levels of three types of speech distortion (additive speech‐shaped noise, peak clipping, and vocoderization). Recordings by two adult male speakers of the different test materials were processed by the three distortion systems, and output recordings were administered to a group of listeners. The results of the study demonstrate that the relation between the various test scores is not unique but depends considerably on the type of speech distortion employed. |
