Speech processing of audio signal

Abstract

An apparatus for speech processing comprises an input (101) arranged to receive an audio signal comprising a speech audio component. A determiner (105) generates a breathing waveform signal from the audio signal where the breathing waveform signal is indicative of a lung air volume of the speaker as a function of time. A speech processor (103) performs speech processing of the audio signal where the speech processing is dependent on the breathing waveform signal. The speech processor (103) may determine one or more breathing parameters, such as a breathing rate, breathing volume, timing of inspiration intervals etc., and the speech processing may be adapted in response to such breathing parameters. The speech processing may typically be a speech enhancement or a speech recognition processing.
