Deepfake voice detection in telecom networks

Deepfake voice technologies are fundamentally challenging trust in telecom voice services. As synthetic speech becomes increasingly realistic, traditional reliance on human perception is no longer sufficient to verify authenticity. This shift requires telecom networks to assess voice authenticity in real time. By combining IP Multimedia Subsystem (IMS) based media analysis with Service Management and Orchestration (SMO), network-level deepfake voice detection enables scalable, low-latency trust assurance while supporting new categories of trusted voice services.
