Abstract

This paper deals with perceptive test methodologies to assess speech
quality of telecommunication systems. Faced with drawbacks of
typical methodologies recommended by ITU-T, a new way to assess
speech quality is investigated, by collecting reaction times and
performances when subjects are achieving tasks involving degraded
speech signals. A dual task with a digit recognition memory task and
a letter recognition task is proposed. Three different quality
levels are applied to audio signals describing digits and letters.
The results show significant differences of performances and
reaction times between the three quality levels.
