Abstract
A computer-implemented method for transforming audio input data into audio output data is provided. The method comprises receiving audio input data, providing background sound data by separating speech components from the audio input data by using a speech removal module, determining acoustic scene data, linked to an acoustic scene matching the background sound data, by using an acoustic scene classifier module, selecting a specialized noise reduction module based on the acoustic scene data, and processing the audio input data by using the specialized noise reduction module such that the audio output data is generated.
Claims13
A method for transforming audio input data into audio output data, the method performed by a receiver device wherein a receiver G-NR module and a Time-Frequency (T-F) mask detector are arranged in the receiver device, the method comprising:
- receiving audio input data;
- providing background sound data by separating speech components from the audio input data by using a speech removal module;
- determining acoustic scene data, linked to an acoustic scene matching the background sound data, by using an acoustic scene classifier module;
- selecting a specialized noise reduction (S-NR) module based on the acoustic scene data;
- generating the audio output data by processing the audio input data using the specialized noise reduction module,
- wherein the speech removal module is configured to generate the background sound data by combining the audio input data with a time-frequency mask;
- determining if the T-F mask is received from a transmitter device, and either
- deactivate the receiver G-NR module when the T-F mask is received by the receiver device, or
- activate the receiver G-NR module when the T-F mask is not received by the receiver device such that the T-F mask is provided by the receiver G-NR module.
A hearing device, comprising:
- a processing device, comprising:
- a receiver device arranged to receive audio input data from a transmitter device, the receiver device comprising:
- a speech removal module configured to provide background sound data by separating speech components from the audio input data,
- an acoustic scene classifier module configured to determine acoustic scene data, linked to an acoustic scene matching the background sound data,
- a specialized noise reduction selector configured to select a specialized noise reduction module based on the acoustic scene data,
- an output data generating module configured to process the audio input data by using the specialized noise reduction module such that audio output data is generated,
- wherein the speech removal module is configured to generate the background sound data by combining the audio input data with a time-frequency (T-F) mask;
- a receiver generic noise reduction module configured to provide the T-F mask based on the audio input data, and
- a T-F mask detector configured to:
- identify whether or not the T-F mask is transmitted from the transmitter device, and either of:
- deactivate the receiver G-NR module when the T-F mask is transmitted from the transmitter device, or
- activate the RX G-NR module when the T-F mask is not transmitted by the transmitter device such that the T-F mask is provided by the RX G-NR module.
