Speech recognition enhancement using beamforming and a genetic algorithm

Speech recognition enhancement using beamforming and a genetic algorithm

This paper proposes a genetic algorithm (GA) based beamformer to optimize speech recognition accuracy for a pretrained speech recognizer. The proposed beamformer is designed to tackle the non-differentiable and non-linear natures of speech recognition by employing the GA algorithm to search for the...
