There are 27.8 million hearing impaired people in China, of which 5.5 million are suitable for cochlear implant surgery, and less than 5% of them have cochlear implants. On September 27, Tencent announced the launch of “Operation of Nature”. In the future, Tencent will open Tencent’s Teana AI audio technology for free, so that more public welfare developers, equipment manufacturers, NGOs and industries can share this technology, and help the hearing impaired solve the “inaudible” problem.

A cochlear implant is an electronic device that converts sound into electronic signals and stimulates the auditory nerve to restore or reconstruct the hearing function of the deaf. But being audible does not mean that you can hear clearly. In the ears of hearing-impaired people, only the male voice is thick and the female voice is thin—the others seem to be no different.

In the industry, it is often used “like walking into a misty bathhouse”-such a terrible visual effect, to compare the hearing experience of the hearing impaired.

Hearing impaired people not only have difficulty distinguishing various sounds, but they also cannot block noise. For example, in the vegetable market, various sounds come and go one after another. When a person with normal hearing goes to a vegetable stall to buy food, he can automatically block the noisy background sound and hear the vegetable stall owner’s words clearly. Butthe hearing impaired people cannot.

According to the test data of Nuoerkang, the combination of Teana technology and cochlear implant greatly improves the performance of speech recognition, which has a positive effect on improving the hearing experience of the hearing impaired.

The average recognition rate reached 96.28%, of which the noisy speech recognition rate was 93.38%, and the voice recognition rate in ambient noise reached 94.24%; the mobile phone App was implanted with Teana technology, and the mobile phone dual-microphone array noise reduction signal-to-noise ratio increased by 20dB, MOS The score increased by 0.3-0.5.
