How to enhance the target signal in the scene where the strong ground noise and the multi-directional competitive speech noise exist at the same time? >The person in the noisy meeting. >The person in the noisy aircraft.
>The person in the noisy high-speed railway.
>The person who wear the hearing aids or the cochlear implants.
These four scenarios need the clean and clear speech signals, so as to obtain the high quality speech recognition rate.
The design of the conventional microphone array almostly just remove the strong ground noise to pick up the target signal, and little design for the removal of the competitive speech noise in the market at present. Therefore, the microphone array can not obtain the high quality speech signals when the energy of competitive speech is weak.
On the contrary, the speech recognition products have been very perfect in the function of the language recognition and the speech transcription in the market at present. If you can pick up a clean and clear target signal, you can get a good result by using the speech recognition products.
The SKC have developed an algorithm which can pich up the clean and clear speech signals by removing the strong ground noise and the competitive speech noise. You can clearly see its excellent effect in the following three images.
