VoiceShield is an Android-based, real-time fraud-prevention solution that detects two distinct risks during live calls: DeepVoice(AI-generated or manipulated voices) and voice-phishing intent. Existing detection services typically assess voice authenticity and fraudulent intent separately; VoiceShield analyzes both the authenticity of the voice and the social-engineering intent of the conversation in real time. In the VoiceShield Android app, its dual-detection architecture runs on-device and delivers separate DeepVoice and Voice Phishing results through a compact overlay, text, sound, and vibration. Users can review the reasons for each warning and their accumulated risk history after the call. Designed especially for seniors who use mobile banking, VoiceShield can also be integrated into banking, telecom, mobile-security, and public-service applications through a partner SDK. It shifts fraud protection from post-incident reporting toward actionable warnings before users transfer funds or disclose personal information.
