On-line simulation modules for teaching speech and audio compression techniques
V. Attl, Andreas Spanias · 2004
In this paper, we present a collection of software educational tools for introducing speech and audio compression (or coding) techniques to undergraduate and graduate students. These speech processing tools enable online simulations of speech compression algorithms that are being used in digital cellular phones, Internet streaming applications, teleconferencing, and voice over Internet protocol (VoIP) applications. This simulation software is accompanied by a series of computer experiments and exercises that can be used to provide hands-on training to class participants. With this on-line simulation tool and a set of well-complemented laboratory exercises, students can easily comprehend the basic techniques involved in speech and audio coding algorithms. Specific functions t hat have been developed include the typical modules that are usually embedded in CD-players, MP3-players, and mobile phones. Details on the software, exercises, and assessment data will be provided at the conference.
