Irregularities in microphone distribution enrich the diversity of spatial differences to decorrelate interferences from beamforming target. However, large degrees freedom irregular placements make it difficult analyse and optimize array performance. This article proposes fast feasible optimal design methods with improved performance for human speech. Important geometric features are extracted be used as input vector neural network structure determine arrangements sensors. In addition, a hyperbola method is proposed directly cluster microphones areas produce rich differential distance entropies yield significant signal-to-noise ratio improvements. These can easily applied guide non-computer-aided designs speech acoustic scenes such immersive cocktail party environments.
