Abstract : The purpose of the program was threefold: First, develop a Speech Enhancement Unit (SEU) workstation that would run ANSI Standard C versions of the SEU algorithms on a UNIX platform using a user-friendly Graphical User Interface. Second, test the algorithms and quantify their performance, finding, wherever possible, unpredicted aspects of performance. Compare the latest versions of the algorithms with earlier versions. Third, develop, in Matlab, Automatic Gain Control (AGC) algorithms to ensure dynamic range preservation and prevent clipping, at the back end to improve listening levels for the user, and as a spectral tilt compensation mechanism.
