ABSTRACT:
A probability indication signal V.sub.P indicates the probability that the audio signal received via the input is a speech signal. An analyzing circuit derives (NA) which is indicative of the ratio between a signal power in a first portion of a frequency spectrum of the received signal and a signal power in a second portion of the frequency spectrum. A signal pattern detector detects signal patterns in the analysis signal (NA) in another signal, for example, a music signal. An estimator derives the probability indication signal V.sub.P in dependence on the detected signal patterns.
