在全喉切除者中，加速度计转换的吞咽声音没有显示出液体与糊状物吞咽的声学差异，如在正常人中所发现的。与正常吞咽相比，喉切除者吞咽中食团的舌头推进在时间上更接近与食团流入食管相关的独特光谱变化。解释强调缺乏机械牵引从喉抬高有助于咽食管括约肌开放，和舌头推进喉切除者吞咽的作用增加。
Accelerometer transduced sounds of swallowing in total laryngectomees did not show acoustical differences for liquid vs paste swallows, as are found in normals. Compared with normal swallows, tongue propulsion of the bolus in laryngectomee swallows occurred closer in time to a distinctive spectral change associated with bolus flow into the esophagus. Interpretation stressed the lack of mechanical traction from laryngeal elevation contributing to pharyngoesophageal sphincter opening, and the increased role of tongue propulsion in laryngectomee swallows.
