Abstract	Tracheoesophageal (TE) speakers often have difficulty producing the voiced-voiceless distinction. Phonation offset (POff) as a TE speaker transitions from a vowel to a stop consonant may be altered, possibly contributing to listener misperceptions. The purposes of this study were to: (1) compare the duration of POff in TE versus laryngeal speakers, and (2) compare POff between TE productions that were accurately versus inaccurately perceived. Phonation offset and offset duration as a proportion of the stop gap (%POff) were greater for the TE versus the laryngeal samples. There was no difference in POff or %POff when comparing accurately to inaccurately perceived TE samples. Tracheoesophageal speakers may have less ability to halt neoglottal vibration compared to laryngeal speakers' ability to stop glottal vibration. Comparable POff for accurately and inaccurately perceived TE samples suggests that POff may not be a particularly salient acoustic feature to the voicing distinction, at least for stop consonants. Learning Outcomes: (1) As a result of this activity, participants will be able to describe what phonation offset is relative to the voicing distinction. (2) As a result of this activity, participants will be able to describe phonation offset in tracheoesophageal speakers relative to laryngeal speakers. (3) As a result of this activity, participants will be able to describe whether phonation offset in tracheoesophageal speech has perceptual saliency for listeners. (Author).
