This paper presents a new type of speech segregation method for mobile devices in noisy sound situation, where two or more speakers are talking simultaneously. The proposed method consists of multiple null-beamformers, their minimum power channel selection and spectral subtraction. The proposed method is performed with space-saving and coplanar microphone(More)
The adequacies of the simulation-based assessment of speech recognition systems under noisy conditions are investigated and discussed. To evaluate the speech recognition systems in various environments, it is desirable to collect the test data uttered in the corresponding environments but it is not realistic since enormous works are required. To conduct(More)
