Embodiment Construction

[0031] In the embodiment of the present invention, the characteristic that the meaning of words can be distinguished by the tones of the Chinese speech is used, and the tones in the Chinese speech are emphasized, thereby improving the recognition rate of the Chinese speech by the user.

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0033] An embodiment of the present invention provides a Chinese speech signal processing method, figure 1 It is a flow chart of the steps of the method, the method comprising:

[0034] Step 101: Perform syllable segmentation on the Chinese speech signal to be processed to obtain at least one syllable included in the Chinese speech signal to be processed.

[0035] The Chinese speech signal processing method provided by the embodiment of the present invention may be a processing method for each syllable ...

Abstract

The invention discloses a Chinese speech signal processing method, a device and a hearing aid device. According to the fact that Chinese speech tones have significant characteristics in distinguishing word meanings, a fundamental frequency curve which each syllable corresponds to is adjusted by increasing slope of the fundamental frequency curve which each syllable corresponds to in a Chinese speech signal, corresponding syllables can be composed through the adjusted fundamental frequency curves, thereby the rate of recognition for each syllable tone by sensorineural deaf patients is improved, and the distinguishing capability of the sensorineural deaf patients for the Chinese speech is improved.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a Chinese speech signal processing method, device and hearing aid equipment. Background technique [0002] According to statistics in 2006, about 27.8 million people in my country have hearing impairment. As an effective solution to hearing impairment, hearing aid technology has attracted more and more attention. With the advancement of science and technology, digital signal processing technology is gradually applied to the field of hearing aids. [0003] Deafness is divided into conductive deafness, sensorineural deafness and mixed deafness. Among them, deaf patients suffering from sensorineural deafness account for a considerable proportion. Sensorineural deafness can be divided into cochlear (also called sensory) deafness, retrocochlear deafness, and central deafness. Since an important function of the cochlea is to analyze and process auditory information...
