A large percentage of patients who have undergone laryngectomy to treat advanced
laryngeal cancer rely on an electrolarynx (EL) to communicate verbally. Although …

Persons who have lost their larynx and thus speech functionality need to use a substitution
voice to regain speech. The electro-larynx (EL) is a widely used device but is known for its …

Purpose Current electrolarynx (EL) devices produce a mechanical speech quality that has
been largely attributed to the lack of natural fundamental frequency (F0) variation. In order to …

Despite emergent progress in many fields of bionics, a functional Bionic Voice prosthesis for
laryngectomy patients (larynx amputees) has not yet been achieved, leading to a lifetime of …

Electrolarynx (EL) is a medical speech-recovery device designed for patients who have lost
their original voice box due to laryngeal cancer. As a substitute for human larynx, the current …

Understanding the sound transmission of the neck tissue is necessary and important in
areas such as vocal function evaluation and electrolarynx improvement. In this paper, a …

This thesis presents methods to enhance the speech of patients with voice disorders or with
substitution voices. The first method enhances speech of patients with laryngeal neoplasm …

A total laryngectomy removes the vocal folds which are fundamental in forming voiced
sounds that make speech possible. Although implanted prosthetics are commonly used in …

The electrolarynx (EL) is a widely used device for alaryngeal communication, but the low
quality seriously reduces the intelligibility of EL speech. To improve EL speech quality, a …

Purpose Effects of clicks and tonebursts on early and late auditory middle latency response
(AMLR) components were evaluated in young and older cigarette smokers and nonsmokers …
