Sound recognition

Sound recognition is a technology, which is based on both traditional pattern recognition theories and audio signal analysis methods. Sound recognition technologies contain preliminary data processing, feature extraction and classification algorithms. Sound recognition can classify feature vectors. Feature vectors are created as a result of preliminary data processing and linear predictive coding.

Sound recognition technologies are used for:

• Music recognition
• Speech recognition
• Automatic alarm detection and identification for surveillance, monitoring systems, based on the acoustic environment
• Assistance to disabled or elderly people affected in their hearing capabilities
• Identifying species of animals such as fish and mammals, e.g. in acoustical oceanography
