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.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
