The Vak Framework, Volume I
Every voice agent fails at the seam between hearing and understanding. This book closes that seam.
Build a complete voice agent from scratch — streaming ASR, real-time TTS, and the first call that speaks back — in eight chapters. Written for developers and technical founders building voice AI for BFSI, healthcare, and BPO teams in India.
By Chapter 3, your system answers in real time. Most readers stop for a moment — not because they are stuck, but because hearing their own AI respond for the first time requires one.
