Intelligibility enhancement of audio signals containing speech

摘要

#CMT# #/CMT# 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. #CMT# : #/CMT# 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. #CMT#USE : #/CMT# Used for an audio processing system (claimed). #CMT#ADVANTAGE : #/CMT# The speech processing device processes the audio signal to determine whether the audio signal includes the components which indicates the speech, thus preventing non speech components from entering into the speech processing device, and hence improving the speech components in the audio signal. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit arrangement. 200 : Speech detector 206, 208 : Band pass filters 214 : Correlation device 218 : Low pass filter 226 : Control signal.
