title: [Processing of a speech signal and thereby necessary attention: a contribution to dual performance].
abstract: Speech intelligibility during the performance of a second task (sorting of small plates), and the frequency of sorting in dependence of the phases of speech processing (input-processing-output) are investigated. A fixed speech level (65 dB) is combined with 5 different noise levels (55, 60, 65, 70, 75 dB). The speech material and the sorting task vary in difficulty (words, sentences, small texts; simple and complicated sorting). By rating 3 questions the subjective quality of both tasks is inquired.
  
  
  RESULTS
  speech intelligibility and frequency of sorting vary in dependence of noise level; frequency of sorting varies in dependence of the phases of speech processing and speech material; subjective ratings are corresponding with the performance of both tasks.
