Embodiment Construction
[0020] The technical solutions of the present invention will be further described in more detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] Usually, the received speech signal contains different degrees of noise, which is mixed in the original speech signal, making the original speech signal difficult to recognize. The purpose of speech enhancement is to remove noise from noisy speech and extract the original speech signal as pure as possible. If the voice signal is used to disseminate information to others, it is necessary to optimize and enhance the voice signal so that the voice signal can be received completely and clearly so that the lis...

The invention discloses a device and a method for digital hearing aiding and voice enhancing processing. The device comprises a configuration control module and a voice algorithm hardware processing module, wherein the configuration control module is used for acquiring a work mode and algorithm parameters of a chip according to a configuration mode of the chip; the voice algorithm hardware processing module is used for processing an input voice signal according to the work mode of the chip and the algorithm parameters. When the configuration mode is passive receiving, the work mode of the chip is digital hearing aiding, the algorithm parameters are algorithm parameters for digital hearing aiding, and the voice algorithm hardware processing module processes a first voice signal according to the algorithm parameters for digital hearing aiding; when the configuration mode is active reading, the work mode of the chip is voice enhancing, the algorithm parameters are algorithm parameters for voice enhancing, and the voice algorithm hardware processing module processes a second voice signal according to the algorithm parameters for voice reinforcing. Different voice signals can be processed correspondingly through the same device, the structure is simplified, the size of the device is reduced, all the modules are in a low power consumption state in idle, and accordingly, the power consumption is reduced conveniently.
Description
technical field [0001] The invention relates to the field of speech processing, in particular to a device and method for digital hearing aid and speech enhancement processing. Background technique [0002] Both digital hearing aids and speech enhancements process speech signals. Digital hearing aids process the voice signals of various frequency bands entering the ear to obtain optimized voice signals; voice enhancement processing is usually applied in the field of duplex voice communication, such as duplex intercom equipment and teleconferencing equipment. [0003] There are two ways to realize the existing speech signal processing, one is to use a digital signal processor loaded with speech processing algorithm software, and the other is to specifically design a dedicated integrated chip for speech enhancement or digital hearing aid. However, the digital signal processor has the disadvantages of large size, high power consumption, and many peripheral connection components...
