In this thesis two speech intelligibility testing methods are presented. The first, a subjective test, is a variation of the Diagnostic Rhyme Test (DRT) as described by William Voiers. The second, an objective test, consists of an implementation of two speech distance measures. Existing subjective and objective speech intelligibility tests are also discussed and compared. The Diagnostic Rhyme Test (DRT) is discussed in detail and its implementation and results are described. The Cepstral and Log Likelihood speech distance measures are discussed and their implementation and results are described. Finally, the results of the DRT intelligibility scores are compared and contrasted with the distance measure results for various signal to noise ratios.
