This document provides an overview of Adhearsion, an open source framework for building voice applications using Ruby. It discusses why voice is an important medium, provides code samples, and summarizes key features of Adhearsion like its easy-to-use DSL and support for Asterisk. Use cases like call centers, conferencing, and polling are presented. The architecture, future plans for version 2.0, and potential far-future directions are also outlined. The presentation aims to illustrate how Adhearsion brings modern development practices to telephony.
