Embodiment Construction

[0082] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0083] Nowadays, the popularity rate of portable smart terminals (such as mobile phones) is getting higher and higher, and the computing power of the general-purpose processors of the portable terminals is also getting stronger and stronger. However, most hearing aids do not currently have a corresponding voice enhancement method that can realize the hearing aid function and match the corresponding portable terminal. The built-in algorithm of the existing hearing aids is fixed in the processor and cannot be intelligently upgraded as the processor changes. Such as figure 1 As...

Abstract

The embodiment of the invention discloses a voice enhancement method and device for a hearing aid device, and relates to the fields of medical electronic technology and audio signal processing. The method in the embodiment of the present invention includes: acquiring the four-channel audio data of the hearing aid device; extracting the acoustic environment features from the acquired audio data, and obtaining the acoustic scene corresponding to the audio data; The data is sub-channel sound compensation and voice enhancement; two channels of enhanced audio data are output. The terminal performs speech enhancement processing on the acquired audio data on the portable terminal, and finally outputs two channels of real-time audio data. Intelligently improves the sound quality, greatly improves the popularity of hearing aids, and can achieve better hearing aid effects and enhancement methods. At the same time, because the audio data processing is not solidified on the hearing aid device processor, but based on the general processor of the portable terminal The chip is conducive to future system upgrades and the improvement of voice enhancement methods.

Description

technical field [0001] The invention relates to the fields of medical electronic technology and audio signal processing, in particular to a voice enhancement method and device for a hearing aid device. Background technique [0002] Today, our country has entered the era of accelerated aging society. The increase in the life expectancy of the elderly and the excessive application of electronic products lead to a decline in hearing and the number of people who are injured is on the rise. In recent years, with the improvement of medical care, the elderly wearing hearing aids The proportion of hearing-impaired patients has been increasing. Today, hearing aid technology is based on advanced digital signal processing, wireless communication and artificial intelligence. With the rapid development of technology, the size of hearing aids is getting smaller and smaller, and the functions of hearing aids are becoming more and more comprehensive, such as multi-channel wide dynamic rang...
