Week 29: Voice AI Foundation — May 10 – 16, 2025
TL;DR: Voice AI is here. A 3-tier voice agent system handles inbound calls with speech-to-text, AI processing, and text-to-speech — all in real-time.
Highlights This Week
- Designed 3-tier voice architecture (STT → AI → TTS)
- Integrated speech-to-text for real-time transcription
- Built the voice agent framework for call handling
3-Tier Voice Architecture
Traditional IVR systems are frustrating. Our voice AI is conversational. Callers speak naturally, the system transcribes in real-time (STT), processes intent with Claude (AI), and responds with natural speech (TTS). It handles appointment booking, status inquiries, and emergency routing — all without pressing buttons.
How It Works
Inbound calls connect to a WebSocket that streams audio to the STT engine. Transcribed text feeds into the appropriate AI agent (sales, scheduling, or support). The AI response is synthesized to speech and streamed back. The entire round-trip targets under 2 seconds for natural conversation flow.
What’s Next
Twilio SMS integration for text-based communication.
