A curated, developer friendly learning path for building real-time voice AI agents from your first STT call to scaling production telephony.

Voice AI has moved from research demos into shipping product in under three years. The modern stack is converging around a clear pattern: a real-time transport layer (WebRTC or telephony), a streaming pipeline of speech-to-text → LLM → text-to-speech, and a turn-taking model that decides when the agent should speak. This list is structured to mirror that learning order start with the foundations, pick a framework, then drill into individual components and production concerns.

Resources are tagged 🟢 Beginner, 🟡 Intermediate, or 🔴 Advanced. Prefer free official docs and vendor-neutral guides; flag where authors have commercial interests.

Read top-to-bottom if you're brand new. The recommended path:

1. Foundations → understand the pipeline and latency budget
2. Frameworks → pick one (LiveKit Agents or Pipecat are the safest open-source bets) and ship a hello-world
3. Components (STT, TTS, LLM, VAD, turn detection) → swap pieces to learn what each layer does
4. Transport & telephony → connect to a real phone number
5. Evaluation, production, ethics → make it safe enough to ship

1. Foundational concepts and learning paths
2. Frameworks and orchestration platforms
3. Speech-to-text (STT / ASR)
4. Text-to-speech (TTS)
5. LLMs for voice and real-time AI
6. Voice activity detection and turn-taking
7. WebRTC fundamentals
8. Telephony and SIP
9. Tutorials and hands-on projects
10. GitHub starter repos and awesome lists
11. Datasets and benchmarks
12. Beginner-accessible research papers
13. Evaluation and testing
14. Production, deployment, and scaling
15. Ethics, safety, and regulation
16. Blogs and newsletters
17. Podcasts
18. Communities
19. Conferences and events
20. Hackathons and competitions

Start here. These resources establish the mental model of the voice agent pipeline and the latency budget you'll fight for the rest of your career.
