- Abstract:
- Abstract: To improve the speech recognition in noisy environment, the microphone array-based speech enhancement methods are applied in the front-end signal acquisition for cochlear implant. As size restriction in cochlear implant, dual-microphone signal acquisition is the most common mode, and the system beamforming can be used in ambient signal suppression. Parameters of delay, weight, frequency and distance can influence the beam patterns of dual-microphone system. Herein we research the dual-microphone based signal acquisition in cochlear implant and the beamforming feature for different parameters, which provides supports for the research of speech enhancement based on dual-microphone mode.
