Thesis (Ph.D.)--Indiana University, 2006.

Tracheoesophageal (TE) speech is generated when air is forced through a prosthesis that then vibrates the pharyngoesophageal (PE) segment. Previous research documents that TE speakers use greater airflow and pressure to vibrate the PE segment compared to typical laryngeal speakers; however, the effect of these variations on respiratory control for speech has not been investigated. The purpose of the current investigation was to determine how respiratory control for speech is maintained by TE speakers.

520 $a Tracheoesophageal (TE) speech is generated when air is forced through a prosthesis that then vibrates the pharyngoesophageal (PE) segment. Previous research documents that TE speakers use greater airflow and pressure to vibrate the PE segment compared to typical laryngeal speakers; however, the effect of these variations on respiratory control for speech has not been investigated. The purpose of the current investigation was to determine how respiratory control for speech is maintained by TE speakers.
520 $a Chest wall kinematics, lung volumes, and temporal and aerodynamic measures of speech were obtained from 20 highly intelligible male TE speakers. Chest wall kinematics and lung volumes were measured via respiratory inductance plethysmography and aerodynamic measures were acquired with a circumferentially vented facemask and intraoral pressure tube. Speaker tasks included tidal breathing, spontaneous speech and reading of the Rainbow Passage. A repeated-measures MANOVA (SPSS) was conducted on the lung volume and kinematic data.
520 $a TE speakers used greater lung volumes at initiation (VCI) and lower lung volumes at termination (VCT) than laryngeal speakers in previous studies. TE speakers' VCI and VCT were significantly different between reading and spontaneous speech. As a group, TE speakers had chest wall kinematics that were similar to what have been reported for healthy subjects, but differences in rib cage and abdomen control were noted for some subgroups of subjects. In addition to the differences in lung volumes, TE speakers produced approximately 67% of the syllables per breath group compared to laryngeal speakers. Despite the reduction in syllables per breath group, TE speakers took grammatically-appropriate inspirations during speech and reading, with greater accuracy during speech than reported for laryngeal speakers.
520 $a The similarity of chest wall movements for TE and laryngeal speakers suggest a robust neural control of the rib cage and abdomen for speech. By contrast, differences in lung volume usage for TE and laryngeal speakers are likely due to the interaction of many factors associated with a laryngectomy including the voice prosthesis, PE segment, respiratory compromise and loss of laryngeal afference.
