A speech intelligibility test in realistic environments has been designed and performed deploying 51 subjects. A single set of speech samples distorted by various background noises and low bit-rate coding techniques has been used - without and with additional (parallel) psychomotor tasks. The addition of psychomotor tasks to the test simulates realistic environments. The differences in intelligibility test results between standard laboratory and parallel task test methodology were identified. Overall, the intelligibility of regular tests was mainly higher than for tests with a parallel task. Intelligibility results of certain samples have been found counterintuitive, which is possibly explained by a different mode of thinking under parallel task conditions.
