Microphone array based joint optimization framework combining GSC and LDA for outdoor multi-source recognition

Key Points

• This framework aims to improve outdoor multi-source recognition notably.
• The joint optimization achieves significant recognition accuracy enhancements of up to 30% in controlled tests.
• Assessment using a microphone array and combining Geometric Beamforming and Linear Discriminant Analysis led to successful optimization results.
• The approach highlights the potential for broader outdoor applications but may require further testing across various environmental conditions.
