EysholdtAbstractIn 20 to 40 percent of all cases of laryngeal cancer, total laryngectomy has to be performed,i.e. the removal of the entire larynx. For the patient, this means the loss of the natural voiceand thus the loss of the main means of communication. A popular method of voice restorationinvolves a shunt valve (“voice prosthesis”) between trachea and pharyngoesophageal segmentwhich establishes the tracheoesophageal (TE) substitute voice. From time to time, the substitutevoice has to be evaluated by the therapist for the purpose of reporting therapy progress. This eval-uation is subjective; it is therefore dependent on the particular expert’s experience and similarfactors. In the frame of this thesis, it was examined how automatic methods can be used in orderto provide an objective means of the evaluation of substitute voices.There are some established objective measures which are, however, restricted to the evalua-tion of sustained vowels.
