Abstract: Self-estimated and measured intelligibility were compared using different instructions in speech audiometric tests. The results of 69 tested persons reveal that there exist speech levels in both test procedures where the intelligibility reaches 0% or 100%, respectively. In general, self-estimated intelligibility was significantly higher than real identification. Therefore, the self-estimation of intelligibility does not appear as an appropriate procedure to automated speech audiometry. The results are a speech audiometric equivalent of the subject's to have correctly understood speech in daily life in which in fact was misunderstood. Connections to central speech processing seem to be possible. Audiologists might be influenced by the effect of overestimation of speech intelligibility as well. However, preliminary investigations concerning pseudohypacusis show different results.
