TL;DR: The results revealed that the opposition of the voicing sources used in esophageal speech production to airflow through them is substantial and larger than that established for the normal, laryngeal source.

TL;DR: The specific goal of the present project was to determine whether speech, i.e., words spoken by female esophageal and tracheoesophageaal talkers, could be enhanced by means of LP-based analysis and synthesis methods, and it was demonstrated that alaryngeal speech enhancement was accomplished.

TL;DR: An initial description of voicing source signals produced by alaryngeal speakers is generally supportive of the hypothesis of differences in source properties among normal, esophageal, and tracheoesphageal voices.

TL;DR: The mechanism esophageal speakers employ to regulate fundamental frequency is substantially different from that employed by normal speakers and that the identity of physical variables underlying the perception of roughness severity in naturally produced human speech is not well understood.
