The method includes the following. A synthesized sound signal is received through a network. Noise interference transferred through the network in the synthesized sound signal is determined according to a reflection-cancelling sound signal. A coding threshold is determined according to the noise interference. A sound watermark signal in the synthesized sound signal is identified according to the coding threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Identifying method of sound watermark and sound watermark identifying apparatus","description":"An identifying method of a sound watermark and a sound watermark identifying apparatus are provided.
