Conversational AI & Chatbots Market: 10-Day AI Voice Agent Stops Scam Calls
A developer built 'Suraksha Saathi', an AI voice agent prototype to help families detect and respond to scam calls in 10 days. The agent uses Deepgram for speech recognition, a Google Gemini model for reasoning, Murf AI's Falcon TTS for fast speech output, and LiveKit for real-time connectivity. Features include Hindi support via Devanagari-only output, a consent-based memory to remember callers, a panic button that alerts a human fraud team via Discord, real-time scam tracking dashboard, and mid-call voice-engine handoffs to escalate to an investigator persona. The author published the post on DEV and shared source code on GitHub.
Hands-on technical walkthrough of a rapid conversational-voice agent prototype using speech, LLM, and real-time audio stack; relevant to teams building voice/agent experiences but not industry-shifting.
