US 2026/0229222 A1 · 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 which is indicative of a lung air volume of the speaker as a function of time. A segmenter (107) segments the audio signal to generate speech segments of the audio signal in response to the breathing waveform signal. A speech processing circuit (103) performs a speech processing of the audio signal by applying a segment based processing to the speech segments. In some cases, the breathing waveform signal may be generated from the audio signal, e.g. using an artificial neural network. The approach may provide improved speech processing more closely reflecting the current speech properties.
