title: Speech enhancement for an artificial larynx using a low-dimensional model of the hearing process.
abstract: After total laryngectomy the normal voice can be replaced by an electronic artificial larynx (AL). However, the results of the surrogate voice are not overall satisfying due to a robotic clattered sound of that prosthesis. In this paper the results of a sound investigation for an AL are presented. This work is part of our AL research project of laryngectomee's speech enhancement. As a result an autoregressive model of the hearing process is derived that can directly be used for speech enhancement.
