dc.description.abstractThe Minimum Variance Distortionless Response's performance can be increased by improving its capability of alleviating unwanted noise, third-party speaker, complex recording scenario, interference to enhance speech enhancement. With the inventions of new smart acoustic equipment, microphone array technology is often preferred used for dealing the more complex problem of speech enhancement. The signal processing methods, which steers the beampattern to the direction of sound source, are named beamformer. In this contribution, the author proposed method for enhancing the effectiveness of MVDR beamformer in presence of complex environment with the aim to achieve the target directional speaker's component while suppressing all surrounding noise. The illustrated experiment was confirmed with the improvement of the signal-to-noise ratio from 4.7 (dB) to 8.1 (db). the obtained speech quality satisfied the requirement of improving speech quality in complex recording scenario. The suggested technique can be used widely in other speech applications with multiple microphones.vi_VN
