Vapi: Revolutionizing Voice AI for Developers and Businesses
Vapi is a cutting-edge voice AI platform designed to simplify and enhance the way users interact with technology through voice. It is specifically tailored for developers and businesses looking to integrate advanced voice AI capabilities into their applications.
Core Functionality
At its core, Vapi acts as an orchestration layer over three key modules: the transcriber, the model, and the voice. These modules work together to intake raw audio, transcribe it into text, apply natural language understanding, and generate synthesized voice responses. This orchestration ensures seamless voice recognition, natural language understanding, and voice synthesis, transforming user interactions into more intuitive and engaging experiences.
