Enhancement of esophageal speech by injection noise rejection
Hector Raul Javkin, M. Galler, Nancy A. Niedzielski · 2002
Esophageal speakers, who produce a voice source by bringing about a vibration of the esophageal superior sphincter, must insufflate the esophagus with an air injection gesture before every utterance, thus creating an air reservoir to drive the vibration. The resulting noise is generally undesired by the speakers. This paper describes a method for the automatic recognition and rejection of the injection noise which occurs in esophageal speech.
