The JAM suite: a voice-enabled network-based virtual band application

ABSTRACT

The Java Audio Music-suite (J.A.M. for short) is a suite of applications that provides tools and audio processing utilities for musicians. Its core functionality includes a means whereby musicians who are geographically dispersed can play music together. An additional utility determines the actual musical notes from a piece of music using Fourier Transform techniques. All of these functions are complemented by a voice-enabled, animated help agent that takes in voice commands using speech recognition and reports errors via text-to-speech technology.
