The use of speech prosthesis after total laryngectomy has become an international standard for voice restoration today. Provox II voice prosthesis is not permanently inserted, and as such, it must meet the criterion of achieving prolonged retention time within the walls of tracheo-esophageal fistula (TEF).

On the contrary pitch control did not received much attention. Pitch has an important role not only in singing but also in the prosodic characteristics of speech. To our knowledge pitch variations have been s...

OBJECTIVES To assess the merits of computer-aided voice analysis procedures for very irregular voices of patients after total and laser surgical partial laryngectomy, and to characterize qualitative differences in speech and voice function between these 2 groups of patients.

INTRODUCTION After total laryngectomy, voice rehabilitation can be achieved by use of voice prosthesis insertion (e.g., BlomSinger, InHealth Technologies, Carpinteria, CA; Provox, Atos Medical, H€orby, Sweden; Tracoe, Tracoe Medical, Frankfurt, Germany) or an esophageal voice or assistive digital speech device (e.g., Servox, Servox AG, Troisdorf, Germany). Various studies have shown that insert...
