Abstract
An audio processing system includes a speech detector that receives and processes an audio input signal to determine if the input signal includes components indicative of speech, and provides a control signal indicative of whether or not the audio input signal includes speech. A speech processing device receives the audio input signal and processes the audio input signal to improve its quality if the control signal indicates that the audio input signal includes speech.
Claims25
Circuit arrangement for improving the intelligibility of audio signal that may contain speech (px), comprising:
- a speech detector that detects speech in the audio signal and provides a control signal to control a speech processing device that processes the audio signal.
A method for processing audio signals (I) possibly containing speech, where speech or speech components are detected in an audio signal (I) and a control signal (S) is generated and provided to control a speech processing device based upon the outcome of the detection.
An audio processing system, comprising:
- a speech detector that receives and processes an audio input signal to determine if the input signal includes components indicative of speech, and provides a control signal indicative of whether or not the audio input signal includes speech;
- and
- a speech processing device that receives the audio input signal and processes the audio input signal to improve its quality if the control signal indicates that the audio input signal includes speech.
