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.
Key Takeaways & Evidence Grounding
- Author built an AI voice agent named Suraksha Saathi in 10 days.
- Architecture: Deepgram (ASR) → Google Gemini (LLM) → Murf AI Falcon (TTS) → LiveKit (real-time audio).
- Agent enforces Hindi output in Devanagari, implements consent-based memory, and a panic button that notifies a human fraud team via Discord.
- A live dashboard tracks scam types in real time and the call flow supports mid-call voice-engine switching between personas.
- Source code is publicly linked from the article (GitHub repository).
