AI Analysis & Value Prop

Data collection was carried out using high-fidelity microphones recorded in various academic lectures and conference environments, complemented by professional audio equipment to reduce background noise. Multi-round annotation and consistency checks were conducted, with annotations completed by an expert team in the fields of linguistics and speech processing to ensure high accuracy and completeness. Data preprocessing includes steps such as audio slicing, noise reduction, and feature extraction, stored in WAV file format for cross-platform use.
