Embodiment Construction

[0017] A new type of super noise reduction hearing aid speech processing system of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] combined with Figure 1-2 , a new type of hearing aid speech processing system with super noise reduction, including a microphone (such as a subsequent speech recognition unit including a microphone, which can be omitted here), a digital speech recognition unit, a digital speech synthesis unit, a hearing aid dedicated DSP processing unit and a receiver;

[0019] The microphone is used to collect the sound signals emitted by the human voice around the hearing loss patient;

[0020] The digital speech recognition unit is connected with the microphone (or the unit comes with a microphone), for converting the sound signal collected by the microphone into text information;

[0021] The digital speech synthesis unit is connected with the digital speech recognition unit, and is used fo...

Abstract

The invention discloses a novel ultra-strong noise reduction hearing aid voice processing system which comprises a microphone, a digital voice recognition unit, a digital voice synthesis unit, a hearing aid special DSP processing unit and a receiver. The digital technology is utilized to decompose, remodel and reconstruct the voice signal, the accuracy and high definition of the signal transmission content are ensured, the receiving and understanding during voice communication are facilitated, especially in a noisy human voice environment, the signal-to-noise ratio of a human voice signal which is wanted to be heard by hearing-impaired people can reach or exceed the level of a current high-end digital hearing aid, and the user experience is improved. Therefore, a patient with hearing loss can easily hear and clearly hear voice information of others, and an excellent noise reduction effect is achieved in a complex environment. And meanwhile, in a voice synthesis link, the voiceprint characteristics of the original input voice main signal are grabbed, and the output voice with the same voiceprint characteristics as the original input voice main signal is generated, so that the higher voice recognition requirement of the hearing loss patient is met.

Description

technical field [0001] The invention relates to the technical field of hearing aids, in particular to a novel and super noise reduction hearing aid speech processing system. Background technique [0002] Traditional digital hearing aids are simply composed of a microphone, a dedicated DSP processor for hearing aids, and a receiver. The microphone is responsible for collecting external sound signals. If the external signals have noise signals, they are also collected together with useful voice signals. Medium and high-end hearing aids will use beams. The shaping technology filters a part of the noise, and then transmits it to the hearing aid dedicated DSP for digital processing, which includes traditional multi-channel technology, WDRC technology, noise reduction technology, etc. Finally, the signal processed by DSP filtering, noise reduction, and personalized gain amplification and compensation is output through the receiver and enters the ear of the hearing-impaired patient...
