Embodiment Construction

[0021] exist figure 1 A block diagram of a device 5 for interference suppression in recorded audio signals is shown in .

[0022] In a shielded noise environment (for example in the passenger compartment 1 of a passenger car (Pkw)), certain instruments and vehicle components operating in the vehicle cause noises which make it possible to control the instrument 4 to be operated by means of voice It becomes difficult to recognize and translate voice commands 31 uttered by a vehicle occupant, for example the vehicle driver 3 .

[0023] The device 5 includes at least one sound recorder 51 , preferably a microphone, which is arranged in the vehicle interior and serves to record voice instructions or voice commands 31 uttered by a user 3 , for example the driver. In the preferred embodiment described here, at least two microphones 51 and 52 are provided. These microphones are arranged here in the roof of the vehicle interior in front of the head of the vehicle driver, it being ass...

Abstract

The invention relates to a noise suppression facility and method. The noise suppression facility includes a detection module (55) for detecting the operating status of at least one component (11, 12,13, 14, 21, 22, 23, 24, 25) generating noise in an operating state, a control module (54) for generating control parameters (540) according to the entered operating state, and a signal processing module (53) for processing the audio signal (510); according to a processing mode controlled by the control parameters (540), a useful audio signal (530) resulting from the processing is outputted.

Description

technical field [0001] The present invention relates to a method and a device for denoising an audio signal and voice control of an instrument having the same. Background technique [0002] Methods for voice control, ie for controlling devices by means of spoken voice commands, for example in mobile phones or so-called smartphones. In addition, for example in the field of motor vehicle electronics, for example for operating a driver information system operating in the vehicle to select a function and for carrying out further operations within the selected function, for example for the purpose of input into the car navigation system. [0003] Interpretation of voice commands recorded via the microphone on the device side becomes difficult in disturbed environments due to the noise components contained in the microphone signal. [0004] A method and a device are known from EP 0411360 A1 for de-interfering recorded voice signals in a motor vehicle, which are used to control a...
