Problems solved by technology

[0004] If the above-mentioned fixed inflection point frequency is too low, it will seriously affect Chinese tone recognition, but if the inflection point frequency is too high, this frequency compression hearing aid technology will not help the hearing-impaired people much. Therefore, the fixed inflection point frequency setting makes it impossible to use high Accurately compress the audio frequency information to the residual hearing range of the hearing-impaired patients, which hinders the improvement of the speech recognition ability of the hearing-impaired patients

Embodiment 1

[0024] figure 1 It is a flow chart of a speech signal processing method in a hearing aid device provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of processing a speech signal received by a hearing aid device. This method can be implemented by a hearing aid device The speech signal processing device in the computer is implemented, the device can be implemented by software and / hardware, the device is configured in the hearing aid device, and the method specifically includes the following steps:

[0025] Step 110, receiving a voice signal.

[0026] The voice signal is received by the voice receiving device (such as a microphone) of the hearing aid device.

[0027] Step 120, extracting the fundamental frequency of the speaker of the speech signal according to the speech signal.

[0028] When a person is pronouncing, according to whether the vocal cords vibrate, the speech signal can be divided into two types: unvoiced and voiced. Voic...

Embodiment 2

[0048] figure 2 It is a flow chart of a speech signal processing method in a hearing aid device provided in Embodiment 2 of the present invention. This embodiment is optimized on the basis of Embodiment 1. The method specifically includes the following steps:

[0049] Step 210, receiving a voice signal.

[0050] Step 220, extracting the fundamental frequency of the speaker of the speech signal according to the speech signal.

[0051] Step 230, according to the fundamental frequency, set the corner frequency of the nonlinear compression.

Abstract

The invention discloses hearing-aid equipment and a voice signal processing method and device thereof. The method comprises that a voice signal is received; the fundamental frequency of a speaker of the voice signal is extracted according to the voice signal; an inflection-point frequency of nonlinear compression is set according to the fundamental frequency; and according to the inflection-point frequency, the voice signal is compressed nonlinearly. According to the invention, the inflection-point frequency of nonlinear compression is set according the fundamental frequency of the speaker according to the received voice signal, fundamental track information without distortion can be transmitted to the largest extent, the accuracy of nonlinear compression in high-frequency voice information is improved, and the speed identification capability of a patient with hearing impairment can be improved.

Description

technical field [0001] Embodiments of the present invention relate to hearing aid equipment technology, and in particular, to a voice signal processing method and device in hearing aid equipment and hearing aid equipment. Background technique [0002] At present, there are more than 20 million hearing-impaired people in the country. Wearing hearing aids can help them improve speech intelligibility. The hearing aid device includes a voice signal processor. The working principle of the voice signal processor is to receive a voice signal, amplify the voice signal through a chip, and then output the amplified voice signal. [0003] However, for severe hearing loss, especially hearing-impaired patients with cochlear dead zones at high frequencies, traditional hearing aids cannot meet their needs. Therefore, the frequency compression hearing aid device came into being. The frequency compression hearing aid device is a new type of hearing aid equipment that makes full use of the ...
