Abstract (en)

The arrangement has a speech detector (200) detecting speech in an audio signal and providing a control signal (226) to control a speech processing device. The device processes the audio signal to determine whether the audio signal includes components which indicate speech. The detector compares a range of detected speech components to a threshold value, and outputs the control signal based on the comparison result. Independent claims are also included for the following: (A) a method for processing audio signals containing speech (B) an audio processing system comprising a speech detector.
