A test signal for a telecommunications appara- tus comprises a succession of segments of real or syn- thetic speech which includes different successions of the same sounds; rarely occurring sounds; and sounds at extremes of level, pitch and duration, so as to be similar to natural speech with redundancy removed. In analysing the performance of the telecommunica- tions apparatus (1) the analyser (8) takes into account the frequency of occurrence of each sound in natural speech.
